I'm sure this has been discussed in more than one thread over the years, but I'll be damned if I go searching for it...

'97 chevy, 5.7 vortec
fuel pump replaced and still sounds like crap. it's been in less than four months and it's had 3 new filters. the pump is a carter and I hate it.

anyone had any good experience with an aftermarket pump for this model chevy? I'm looking at a venom which is about twice the price of the parts store lieftime-warranty carter. anyone have or heard any opinions on this product for any application?

at this point I'm still worried about the damn thing because it's definitely getting louder and tends to get a little hitch in the throttle if I don't replace the fuel filter every month. so I'm convinced I'll just be putting in another pump in the next six months. if I'm gonna do that it's not gonna be this o'reilly's p.o.s. again (third time).

any thoughts?

your own damn thread:

I like my most recent Ho'Reillys Carter.
Original one lasted 124k, last one lasted 25k and sounded like crap the whole time, this one's quiet as a mouse. Must be luck of the draw. The most recent one I put in did strike me as being a more complete kit with instructions in english and a different design on the box, so maybe they've changed something recently...

do what GM did originally...put a delco in it. You ever wonder why that pile of crap you have is half the price of a delco.

I agree.

But the original pumps in my old 98 and in our 99 have always been loud. I figured it was just a Chevy thing

the chevy pump in my scout is a little bit loud, and the one in my camaro can't be heard over the exhaust, but the fuel pump on our 8100 suburban is really f'n loud. It's a chevy thing.

My dad's 97 is loud and he has 130k on his running strong still. He does how ever have powersteering pumps fag out. And he is on the 80k intake manifold gasket replacement program.

TBI dont need as much pressure as Vortec. I'm sure that has something to do with it. On both of my old suburbans you couldnt hear the pumps but on my crewcab the pump has a very distinct whine. I'm prety sure its still the factory pump at 150k miles.

Yea, thats probably right. I remember hearing TBI takes less pressure than other types of fuel injection

I don't think 50psi is enough for vortec

agjohn02

says itll do 60. surely 50 is enough. thats close to what i run on mine.

vortec requires 56-70psi at the rail
racepumps operates at a constant 4 to 50 PSI with most aftermarket pressure regulators, 60 lbs unregulated.

vortecs dont have a rail. HA!

i guess they were referring to the central dealy where all the injector plugs are that the injectors get fed from. I'm sure it won't work. That stupid motor is very sensitive to pressure. My last pump still worked but didn't put out quite enough pressure and the truck wouldn't run at all

they kind of have 8 rails on the inside, eh?

this article is about the six, but it's the same system. Read down a few paragraphs, evidently they are known to be sensitive to fuel pressure fluctuations.

if you consider a sonic straw a rail, then yes.

Fred and Dad just did the intake on my brother's truck, those lines are a "no-no" area on a 200k mile truck!

dude I don't touch that motor any more than I have to. I'm looking forward it's demise so I can put a small aircooled vegetable oil motor in it or better yet sell it grow my hair and beard and hitchhike barefoot. I'm thinking about putting a bicycle drivetrain in the ugly truck and fill the diffs with canola oil so it doesn't pollute any more.
and I luv chix with hairy legs
peace love crabs :flipoff2:

I was hoping Douggie would put 3 sm465s in a row for me. But that would probably be too long so maybe I can put one of them backwards and to the side and put a vdrive between them. Stuff with vdrives is cool
edit: since I just trashed Jason's tech thread I'll erase my posts if everyone else will
