Gas Tank question...
Hey guys,
I'm running an 87 G20 Van fuel tank and I've switched out the pump to a high pressure one to withstand the 5.3. There are three lines coming out of the top of the tank. I only need a return line and a main line. Which one is which? Also there are three wires coming out of the top also. One is the ground, what about the other two? Thanks

Re: Gas Tank question...
Black.....Ground.
Pink.......Fuel gauge. Grey......Fuel pump power. Remove the sender it will be obvious which line is which. But will try from memory.... Left to right.....Vent, Pressure, Return. |
