Re: In-tank or external fuel pump
external is fine if you follow the mounting instructions for drop and distance, and some guys do. it has to do with an external pump sucking fuel from a long straw, and an in tank pushing fuel out of the straw.
I prefer in tank like speedbump because the fuel surrounding it is a great heat sink to keep it cool. back in the day the hot ticket for a universal EFI pressure capable external pump was a bosch unit from an f150 with the efi 5.0
