Ok thanks, I found this looks like it would make a return line easy without dropping the tank. Some say you need it close to the bottom but away from the sending unit. Other say on top opposite of the sending unit or supply. My current return is in my sending unit going straight back into the tank but I cannot make it any bigger so alternate location would be needed if I need it

Thats a -6 AN. If your return line is -8, I would want that fitting to be -8 too.

There are other styles of bulkhead fittings if you dont want to weld a fitting on the tank that may work better.

The thing about bulkhead fittings is you have to be able to get to the backside of the fitting, which means you have to get your hand and a wrench in the tank. If you can do that than a bulkhead fitting is the easiest, best way to do it.

As to where it goes, there is a whole bunch of nonsense out there about that. Try and avoid blowing the fuel right on top of the pickup. That’s about it.

If you mount it say, 3-4 inches on either side of the OE pick up, you’ll be fine. It will put the fuel back in the tank far enough away from the pick up that it won’t matter.
