fuel lines

[nthdrt]

I hear guys in the hobby class saying thier running return fuel lines on the cars. Is there a advantage or disavantage by doing this. Also how would you do this because my pump only has two fittings and the fuel cell has only two lines. I dont understand how to do this with a aftermarket fuel pump

I run a return. Is it an advantage? No, more like an insurance policy. I run a 6 valve pump up to fuel log at the carb. I run a Kinsler Bypass set to 7pri, off the back of the fuel log and a line from there back to the cell. If your cell doesnt have a return fitting, you can always drill a hole and add the fitting. Is it over kill? Some would say yes, but I have never had a fuel supply problem, ever, so.......
