So, how important is a proportioning valve on a off road rig? I am running all new brake lines and if its not important I will leave it out...

Also, i'm using my stock tank in the back of the jeep. I cut all of the fuel lines off when I started the 4 link now i'm trying to put it all back together. The tank has 4 ports (plus the filler tube). One port is the line going to the fuel filter then onto the carb. At the fuel filter there is one input line and two outputs. One of the outputs is the one going to the carb. I believe the other is a return line to the tank. What is the point of that line returning to the tank? I dont know what the other two ports on the tank are for. I believe one is a vent that went to the evap canister but, I don't really remember. It has been over 8 months since I cut all this stuff out and now I dont really remember what went where.

I am a fan of simplifing things so, would there be adverse effects to capping off everything but the supply line and a vent line?
