Chevy gas tank...

[Doug Krebs]

Looking for a 15 gallon suburban/blazer gas tank. The one I got is nasty inside and I don't want to deal with it. I'll just reuse my 30ish gallon tank if no one has one laying around.

[JeepPhisherman]

check your pm's fool

[Doug Krebs]

check your pm's fool

so thats a yes? :flipoff2:

[JeepPhisherman]

the closest thing i've got to chevy laying around is a bow-tie

[Sharpe]

I have a 40 gallon tank out of a C/K series cab and chassis, and a burban with an unknown size tank. It might be a 33 but is more likely a 40. I also have some pickup saddle tanks, they are around 15 each.

[Doug Krebs]

The point of this is to downsize the tank in order to gain ground clearance. i wouldn't be doing this anyways unless I had to drop the tank due to rotting fuel lines. The tank I have now is dented, but I have no reason for a new one unless it's smaller.

Also, you still owe me $35 :flipoff2:

[agjohn02]

you can take a look at the camaro tank i have and see if it will work.

could you measure the length and width of it? Wonder what the sending unit on it looks like.

looks like a camaro sending unit. that'll cost ya though, its got a nice walbro aftermarket pump in it.

[CRaSHnBuRN]

anyone know anything about this one? http://www.galleria-e.com/cgi-bin/Colemans.storefront/en/Product/462301

The dimensions they give don't really match the # of gallons listed, unless thats internal dimensions

[Doug Krebs]

Ok... dropped the tank today. Would have reinstalled it but the damn baffle is broken due to the tank being crushed.

I'm looking for another tank. Hopefully something smaller and something that uses a similar sending unit. Anyone know how large of tanks came in S10's or astro/safari vans? I'm assuming they'd have similar sending units.

Anyone know any junkyards around that sell gas tanks? I'm going to call around tommorow, but just thought I'd ask.

[bburris]

Yours should be fine... With the dents it has it probably only carries about 20 gallons now. Self-clearancing, right? :flipoff2:

[Doug Krebs]

John I maybe coming over again tommorow and taking a closer look. Any idea what kinda fuel pumps they use? Are they the same shape as the TBI?

When you going to be at the shop?

[DRAGOONRANCH]

my 94 s-10 had a 22 gal tank IIRC, that thing could drive forever.

[Sharpe]

The tank I have on pigpen is out of an 85 s10 blazer and I think it hold around 15-20 gallons, its kinda narrow and deep as opposed to wide and shallow like you are looking for though. As far as I know, all GM sending units are the same. In pigpen, as I said, my tank came out of an 85 S10 blazer, but the sending unit is from an 84 carb'd gasser. I am prety sure the hole in the top of the tank is even the same size on the 90's models, but I've never measured to check.

the fuel pump on it is about 1.5" in dia and 4 inches long. it is currently worm clamped to the sender as i found it, so im betting you can put just about anything on there.

Too much money for as little as I use the blazer. Don't foget I's po!

Yeah I know but they generally dont sell gas tanks from junkyards.

Can not clean that tank you got? Karl has cleaned some crappy looking bike tanks out before. The best way it put some cleaner in it and some chain and shake the hell outta it. Easier said that done I know.

I know they don't usually sell them from the bigger yards, but some of the mexi junkyards around here probably would.

I did my motorcycle tank which was pretty easy. I put nuts and bolts in it and sloshed around but with a 25 gallon tank that would suck. It would probably cost half of what a new tank would to clean it and coat it.

I'm going to check out the camaro tank john has again. Yesterday I thought it would be too much trouble, but that was before I saw how bad my tank was.

[colman]

i have one in the parts waggy that might or might not be usable, just another option

[Doug Krebs]

So I got the tank john had laying around. I started looking at it and decided I was going to cut a wedge out of it, as it's a funny shape at the top. I've changed my mind now though. If I'm cutting up tanks, I might as well chop the top of my tank and chop the bottom off the nasty tank I have. Then clean the inside of the bottom piece and weld the two halfs together. Using my style tank, it should bolt in alot easier, than the bastard camaro tank.

Leakage could be an issue, we'll see how good my welding skillz are.

Anyone ever cut on gas tanks? I've heard to fill them with innert gas. My tank still has some residual gas in it. I plan to fill it with water all the way to the brim, the water should displace the gas in theory. I'll do this a couple times. Anyone see a problem with cutting on the tank after this?

[stx4wheeler]

we did this with coops tank of the yota back when it had frool injection. WE braised it back together. His sat outside for months, got rained and such i think, we filled it with water a couple times then, some soap and filled with water, then washed it all out and went to town on it, yet ive heard inert gas is the way to go. Coops worked great.

[eight]

I think you're making this too much work.

[agjohn02]

cut it? is it taller than the one you have?

i cut mine with a saws all. first, rinsed it with water a few times then prayed for no sparks. after i got a good sized hole cut in it, i stuck a torch in to make sure there were no fumes. then welded the flange in it with a tig. it did not weld well.

i say dont cut it, just make it work as is. its too much trouble.

Hmm... Maybe I take a test piece out of the bottom of my tank and see how it welds. If it's ok, I'll go forth with cutting two halves to make a whole. If it doesn't weld good I'll try to figure a way to make that camaro tank work.

[fbronco86]

I welded on my gas tank worked just fine

[tigweld]

rushin truss's F-450 cab and chassis diesel tank has cracked like 3 or 4 times, our fleet machanic just welds it back up with fuel pourin' out crazy chit. I probably wouldn't do it but I have seen it done a couple of times on emptly gas tanks.

I would rather weld on a diesel tank than a gas tank anyday.

The gas flumes will get yeah trust me it will leave a mark. But I should of had gloves on too.


I know I prob should wear gloves when I weld. But I generally use a glove on my left hand and go commado on my right hand.

[fbronco86]

I think you should use a oil bottle like you did on your bike. That would be sweet.

:gigem:

You could pay 400 bucks for a gas tank like I did. I think I am still hurtin in the a$$ on that deal.

[Doug Krebs]

Ok, so I chopped both tanks in half. Garrett helped me with the first one and then he ran off like a little girl.

The two halves fit together pretty good, but I'll probably have to make 1 slice on 2 corners of the bottom piece to make shrink it a little, as it's a tiny bit bigger.

Anyone have a sandblaster I could borrow? I have the air compressor, just need the attatchment deal. I'd really appreciate it! :D

[JeepPhisherman]

I made it to BVWS when he was unlocking the gate to close it, so **** off :flipoff2:

Just give that fif grader some sandpaper and let him go to work.

[Shaggy]

wire wheel on a grinder works fast and has not so much mess

[KrazyKarl02]

Now that you have already cut it in half, The real "correct" way to do it is to put steam in it. The steam heats the gas and makes it evaporate quicker, without getting to hot and going boom.

not knocking your welding skillz, but this is probably going to be pretty tough. and now the part where I reference Monster Garage - on one episode they cut down a diesel tank and the guy did not weld it good enough, anywho, to fix it they ended up using some of that magnum steel tube crap, just a thought if you run into the problem.

That was aluminum if I remember correctly. Once it's welded, I'll fill it up and let it sit for a couple of hours to make sure it doesn't leak.

It's a cute little tank, we'll see if it works.

[jerryg79]

Does gas eat silicone?

If not I'd run a bead over the whole seam once its cooled, just for good measure.

I think the tank I am talking about was chromed, so probably not aluminum. Anywho aren't you worried this smaller tank will keep your highway miles? :flipoff2:

[eight]

I advise to tack about a 16 ga strip on the inside of the tank to use as a backing. Then weld that to each side of the tank, then put a larger bead that would cover both beads over it to ensure no leaks. Make sure its really clean to prevent pinhole leaks from contamination, and use a small wire.

It would be easiest to pressurize the tank with your air compressor and use soapy water to test for leaks. That way when you find a leak you just depressurize and fill it.

This one karl?

They built it out of the chromed peterbilt gas tank right?

Hmm... good idea with the strip inside, I think I'll do that.

It would be nice to pressurize the tank, but I'd have to cap all the holes. The filler neck wouldn't be too hard, but where the sending unit goes might be a pain. Come up with a good Idea for that :)

[tigweld]

put the sendin unit back in Hole filled seems easy to me :flipoff2:

Yeah I guess I'll just have to cap all those holes too.

[CRaSHnBuRN]

I thought I heard about the people who make POR 15 making something that sealed the inside of gas tanks and didn't react with gasoline

[Doug Krebs]

Well I got everything cleaned up and ground clean. Started welding on the backing piece to the bottom half. Got two sides done and ran out of wire. The spool said oct of 2002 on it! I should weld more. Anyways that happened at 9:09 right after home depot closed. I'll start early tommorow morning again.

they do...you acid etch it first and then poor in some epoxy and roll it around in there...it is suppose to work failry well...probably easier than what dougs doing. that's a lot of work for a gas tank!

[JeepPhisherman]

It's not like he has anything else to do or anything :flipoff2:

chirst you're telling me... I have the por stuff left over from the motorcycle. I just smeared it all in the bottom half, as I wire wheeled the whole thing. Waiting for it to dry before install the baffle and the weld the top half on.

Edit: Also I'm not sure how that crap would work with the baffle. I'm not sure it would get under it. The baffle is plastic and I'm not sure it would stick to it, but it would get all over it and probably wind up in clumps inside of it.

[BMFScout]

I didn't read this thread for a few days because I thought, How interesting could a thread about a gas tank be?" You showed me Doug!!

(Sorry didn't mean to be a ****in ******* ;) )

[Doug Krebs]

Got it all welded up and then pressure tested it. Not sure how much pressure I had in it, but I didn't feel like rigging up a pressure gauge. I had a total of six leaks. All of those were tiny cracks from when the weld cooled and contracted the metal around it. All of those spots where where I did a larger weld and obviously got to hot.

Also modified the sending unit to be shorter. Tank height is now 7 inches.

[agjohn02]

you cut it up?!?! i need that tank, i let you borrow it for test fitting!

[DRAGOONRANCH]

Ok, so I chopped both tanks in half.


I thought he only did the one, but guess not....
No respect I tell ya, no respect. :flipoff2:



Garrett helped me with the first one and then he ran off like a little girl.
Teeheehee, that is funnay :beer:
We had an Iraqi dumptruck driver check his tank with a lighter a while back, he lucked out and only lost some hair and eyebrows along with a few nasty burns to his hands and forehead. Put a couple good bulges in the tank too. That was the same job a dozer operator told one of the Iraqis a golf ball was "good eatin" when he asked what it was. Guess he thought it was a jawbreaker or somethin. :flipoff3:
