Thanks. I was told by some friends of mine I can order one for a 98-02 Camaro/Firebird, the wiring is the same ie:power grounds etc.
You cannot run an inline fuel pump in the C5 Corvette. We have 2 tanks. The passenger tank is constantly filling the drivers side tank. It uses fuel pressure from the fuel pump to feed a ventury feed system in the passanger tank to siphon fuel into the drivers tank. An inline pump will pull all the pressure away from the intank pump and ventury system leaving you passanger tank full and the drivers side/pump empty. You can only use an external pump if its ran in paraell with the tank pump or as a completly seperate fuel system. But the factory pump has to remain in the tank running to keep the 2 fuel tanks working properly. The other option is a better intank fuel pump such as a Racetronix 255LPH Walbro or dual intank 255lph Walbro fuel pumps that keep the ventury system working correctly...Nick Yoskin is running dual walbros. PM him for more info..

Wow, thanks for the info!
The problem is I am running only 100 wet shot and my rails drain quick. My fuel pressure drops about 15 psi when nitrous kicks in, going from
60 to 45 psi. Then a split second later it goes back to 60 or so. I have a Walbro 255L in there now. I did JUST the pump and not the wiring harness...you think the wiring harness will help?
Thanks for the help!

This you 98' Vette?? If so a wiring harness will help. You can also get the Kenne bell boost a pump model thats designed to come on for nitrous. That will help a bunch. Probably more than enough for a 100 shot...
If not there's always dual walbros...
Also nitrous direct sells a stand alone fuel system for nitrous. Its a small fuel cell the sits where the battery goes. It has the pump and pressure regulator just for NOS in it. You relocate the battery to the rear of the car...
Really nice setup..

I have a 98. I tried Kenne Bell's website and found nothing. I would rather go with the boost a pump over the stand alone fuel system.

They don't have them listed anymore, but you basically will have it wired to come on at full throttle like the NOS instead of with a boost switch...

The Kenne Bell BOOST-A-PUMP™ is fully adjustable from 1% to 50% with the mere turn of a dial, so pump output can be varied to match your engine's needs. No longer are you "locked in" to a fixed pump capacity and/or pressure. It activates ONLY at full throttle (naturally aspirated) or at 3 psi (turbo or supercharged). And it acts as a voltage regulator by compensating for any and all system voltage fluctuations.
