been trying to get a direct fit fuel pump for a while now for my 2000 3.8, ordered one from fullthrottlespeed but i haven't even gotten charged after 8 days. i need another seller that offers a direct replacement fuel pump that requires no modification. is there such a thing? i noticed racetronix is a sponsor on here and i was hoping he could chime in..

 

You could try giving him a PM, it would probably be easier for him to get in touch with you that way then by the luck of him finding this thread. Are you looking for an aftermarket pump specifically, or will another Delco pump work?

 

didn't have a PM option on his profile unfortunately. i'm gonna need an aftermarket one now that i've already written down on my mail-in order pcm tune

 

Who are you getting a tune from? The high flow pump shouldn't affect the tune, bigger injectors would though. The fuel pressure is being controlled by the fuel pressure regulator.
