Fuel Pump and Nitrous

[White94GT]

I am getting ready to install a nitrous express wet nitrous kit, and i plan on running a 100 shot. Will the stock fuel pump on our cars handle this, or should i upgrade to a better one? Right now the car only has full exhaust if that matters at all. Thanks

Since it's a wetkit you should definately upgrade to a bigger fuelpump. For safety measures. You dont wanna run lean on the juice..

i dunno i went through 4 bottles with stock heads and stock fuel pump with a 125 shot and fpr. it may be hit or miss but it is def a good thing to have

get a Walbro 255lph and b done with it... they're not that expensive and you may as well do it now, rather than later, after you run it lean and really piss urself off cuz you broke it. Cuz then you'll have to pay to fix ur car and go buy a 255 pump.... just my opinon

I figured that I would probably need a new one. What size would be best, 255 lph?

255lph High Pressure

part# GSS340-400 (should come with the installation kit)

I have heard/read that the stock lines and rail (even though our 94-95 rails flow more than the fox's) cannot flow the needed fuel to match the 255 pumps. That is the reason I run a 190.

FWIW I ran a 125 wet shot with my stock pump and never had an issue with the pump. I just got a realy good deal on my 190 and wanted to step up the shot as well. I think most people get the bigger pump at the 150 level.
