Center Section Fuel Pickup Interference
The repop tank has nothing to do with it, it's cause you moved it back. Mine on my scamp was close and i dont think it has been moved back. there really is no reason to move the axle back. center of the wheel whell on the quarter panel is not center of the actual wheel whell. I put a sump in it and my own return line. I also cut off and Tig welded up the factory pick up and return on the sending unit. You can see pics of what I did in my scamp thread below.
