fuel lines

92ranger18 · Aug 8, 2011

Ive done a carbed v8 swap in my truck. It has the stock fuel tank and the in tank efi pump with a return line. I know im gonna need an afpr if i want to run that fuel pump, but wat do i do about the return line?

Well if the regulator doesn't require the return line...... you can always remove the line and cap off the fitting at the tank.
The first carbed ranger I built I ran a mechanical fuel pump, so I removed the pressure line all the way to the tank and capped off the line..... then I used the return line as the mechanical pump feed line.... there is a little flapper valve on the end of the return line in the tank I had to remove..... it looked like it prevented fuel from going back up the return line......so if you cap yours off at the tank it should not be a problem...My 2 cents.

With a stock pump and return line, you need to use a return style fuel pressure regulator. I went that route and found spring-lok to 3/8" NPT fittings to plug them in to the regulator.

Can use a low pressure inline elect pump using the return line as sparky2eh suggested; another way to skin the cat (cheaper).
