-8AN & -6AN in the fuel unit
Unless you are cutting out the three factory fuel fittings on the outside.

I would but there is a big difference between the factory fittings and a -8AN feed fitting. Seems like that defeats the purpose.

Either of these..
gas tank (http://www.summitracing.com/parts/rnb-576-313) and a 4 port sending unit with built in bracket for an intank fuel pump (http://www.summitracing.com/parts/rnb-692-033).
I also have Aeromotives 340 intank fuel pump (http://www.summitracing.com/parts/aei-11169). I'm hoping the pump will fit into this sending unit with no major mods. has anyone done this set up?
As mentioned in this thread people have used factory sending units to AN fittings. The sending unit I have has the flat flares with an o rings. What is the proper AN fitting for this set up?
Do the fittings hold up to the 58 PSI the EFI runs on? I know this tank and sending unit were only rated for TBI 14PSI.
The GMC was fed by a 6 AN fuel line when it was carbureted which now will be a fuel return line. Do I need to run a vent line to a canister?
Pictures and build out to come...........
