LS1 fuel pump?
LS1 into 80 vette. Used a acdelco EP241 but only getting 35-40psi on the rail. I need more because having fuel issues.
For those who did the LS1 conversion what pump did you go with?
I used the 82'vette fuel assembly and then replaced the pump with ep241... what will replace the ep241?

glarior,
I don't know anything about the ep241, but I do know that the 1982 ( and 1984 ) Corvette had throttle body injection, TBI, and these use much less fuel pressure than EFI, even though a TBI is a form of EFI. ( It is an electrically powered fuel injector! ) I think that TBI uses around 12 psi, but modern EFI engines need 45 to 55 psi. So 35-40 is too low for what you need.
Good luck.
