Default 12A tank with EFI

So i need some input on how to resolve this.

Basically, I cannot use a fuel cell, swirl pot, etc. I have an external pump arrangement already and I just need to connect my fuels lines to the tank, somehow.

I have considered just running the 3/8 nipple as my feed. and just reducing down to that 5/16 looking nipple for my return and keep the vent the same.

Another alternative could be to many drill for a bulkhead fitting and then run another line down into the tank, but REALLY don't wanna do that. Seems like a pain to get the shavings out.

Why not just get a fuel tank and sending unit, etc from a GSL-SE that already was equipped with all the necessary FI components? It will likely use the same mounting points for the tank straps etc. Should be a straightforward swap, unless someone else on here knows a little more on this and wants to chime in?

What year is your car? There are three different series of fuel tank used in FBs, and they're not interchangeable.

What is your HP level? Turbo?

What type of driving do you do -- i.e. street, autocross, etc.?

ever thought about just sumping the factory tank? or is that part of the Etc? if not i would just use a bulkhead fitting in the top of the sending unit with a piece of steel tube.. could even use that method to make the return as well
