Hello,
I would like to run a return line to the stock fuel tank. Has anyone ran a return line to there stock fuel tank(i checked the FAQ section)? What would be the trouble free way of doing this? Can I change the sender to a big block? I need help

What kind of truck?

If its a 67-72 behind the seat, many had a stock return line.

My bad. Yes, this is for a 1970 swb truck.

I believe 71 and or 72 had the extra line going into the fuel sending unit, but I think it just went up into the back passenger corner of of the cab.

I think I can use a 72 sending unit. It has two tubes coming out of the top... Has anyone else tried this?

When I installed my TBI unit, it needed a return line......I used a 72 sending unit with the dual lines. I used one for feed, one for return and have had no problems.
