Gas tank sump or in tank PU

[deputydog]

Coming from a NA/NOS background we always ran sumped tanks or fuel cell and big external electric pumps.

With turbo buick any issues with sumped tank and external pump like a Weldon or is the in tank pump/pickup with AN style hat for #8/#6 fuel lines preferred???

I never had issue with sumped tank but have read Buick guys have had issues.

Real stock tank is a dog dish baffle and the aftermarket tanks aren't all the same so watch out there. Ricks Hot Rod tanks are internal baffled if you wanna go the SS route. Don't see many new moded sumped stock tanks these days because internal pumps are getting bigger and bigger with brushless designs and there's even a Duetschwerks 810L single pump that's plenty for most of us. Also IMO external pump is a PIA, I'm ditching my Magnafuel on my GTO this winter.

There's dual pump setups like this Racetronix that's way more than most will need even on E85.
