What I have going so far is this....
Where my Z-Bar was bolted I made a plate with two pipe unions/couplers on it. one side will have a -8 fitting (what I setup my rails to take as it was easiest) and the other will have a -6 fitting (both steel hydraulic fittings as they are cheap) I will do something similar at the rear but will most likely use a 3/8" union (the -8 fittings fit the rail best and will be as big as I ever will need on E-85 if I go that route) inbetween this hard point will be just some SS hardline (AL is cheaper though) flared with tube sleeves and nuts. the flex sections are pushlok hose. WAY easier to assemble (I will never go back unless required for tech).
I will be returning to the tank (my fairlane tank mounts from the bottom so no in trunk hoses other than the filler)
I will be using a "frame" mounted bosch pump (on a plate mounted on bushings to help keep noise down) return will be to a tube with a -6 fitting on the end (to make sure fuel is mostly deposited at the floor of the tank instead of spraying it all over inside the tank)
I had looked at this setup but my tank is barely deep enough for it

I would have also have to notch my trunk floor with a step and would have to drop the tank to access the wiring or fittings on it.
I will be working with a NEW tank and sender so no welding issues.
you might be able to just drill a hole in the tank near the sender and install a bulk head fitting like is used on a fuel cell (with a sealing o-ring) I am not a fan of returning a filler neck on a rear fill tank.....lots of extra fuel hose to run and in a unprotected area.
I am going with the AN fittings since I HATE having to cut hose off barbs that has turned hard and then you are stuck cutting a new piece of hose to length everytime you take something apart.
one option might be to get hose crimped at a napa but it might be just as cheap to use the pushlok hose. try to lay it all out to use as many straight fittings as possible since they are half the price (around $8 for -6)
