yea...thats what i thought. i was really confused about why everybody always makes a big deal about upgrading the fuel pump. i didnt think there was anyway it could make a difference like that. so i was just double checking. sorry about sounding like a moron there.

It's been to not take shortcuts on your fuel setup otherwise you'll lean out your engine and mess it up indefinately... That's why people make it "such a big deal". Just so ya know...

More power?? :rotflmao depends on what Mods you have to justify the need for more fuel. You're not going to get any more power by just installing a high flow fuel pump, if i'm wrong someone please school me.
If you are leaning out in the first place its possible. I gained 10hp top end from pump replacement cos the old one was shot.

the idiot i am i juss left the fuel pump not completely bolted down. after almost a week of juss sittin there... the o ring on the that sits inbetween the top plate and tank got bigger. it doesnt fit in the groove anymore. i guess it expanded for some reason. anyone know wer i can buy another?? i tried osh but they dont have a big o ring. juss sayin this so no one else makes the same mistake. anything else i should be in caution of cuz im puttin the pump in tommaro. thx
