Default fuel pump ?

Ok here it goes.... I am getting my N2O hooked up but I was thinking about replacing my fuel pump and or adding an inline pump. But here is my question. If I put in a inline and keep the in-tank pump how does that work? Wouldn't the inline cause the in-tank to cavitate <sp?>?
Also what would you guys recommend I do and what pump or pumps to go with?
Thanks :seeya

Replace the intank pump with a Walbro 307GS pump and forget the inline. The 307 is a 255lph pump.

Is the Wlabor 307 pump a direct fit? You can buy them pretty cheap under $100 I think. If it jsut simply replaces the stock pump, I might just get one too.. :cool:

Direct replacement. (At least I know it is for '89-'96.) The one specifically for the Corvette is usually about $109.

If you want the last word IMO, on this check out Racetronix. They have a great heavy duty, TRUE plug n' play fuel pump and HD wiring setup for ~$150. They have a LOT of data, (not BS) on their website, including specific applications for C4's that are NO, supercharged, and turbo modified. Of all the stuff that I've done to my car, that was one of the very, very few painless and effective mods.
