[Diy_efi] EFI lift pumps to swirl pot?

[Dan Zorde]

Not sure who started the original thread, but the Australian VL/VN
(mid-late '80s) Holden Commodore used a in-tank lift pump feeding
directly into an external high pressure pump. I'm using this set-up with
a swirl pot inbetween (low pressure tank return from pot and hig
pressure return to the pot) to feed a 400HP Chev350 and that is working
fine.
