Re: Gas vs Diesel Gas Tank Sending Unit
You do not want to return fuel to the bottom of the tank. It'll aerate the fuel. That'll raise hell with the injection system and wear the fuel pump and injectors out... If she'll run with that much air in the fuel.
Might I suggest that you just use the vapor line on the stock sender and build a new supply and return...
You want to factor in assembly... Those clamps don't look very accessible if you don't have the hand size of an 8 year old to reach thru the sender bung. I think I'd modify the stock sender with larger tubes or put a removable PEM-stud or PEM nut bung next to it with the supply and return lines.
