need a fuel pump

[rallysportchic97]

Im about to purchase a new fuel pump within the next few weeks and was doing some research on here and noticed that if I plan to put in a nitrous kit later(might start at 50 shot and go up to 100 shot),that Walbro pumps are good. Im not sure if I would need the regular 255 or the high pressure one. I dont plan to install nitrous for a while but figured since I need a pump now, I might as well already the aftermarket one. Also do I need to replace the regulator as well? If so, gm or aftermarket?

walbo is deff a great system to have. i was just going to add an in line pump but with a 100 wet shot that wasn't the way to go.

I have a walbro 255 in my camaro and it works great. Just took out the old pump, removed the bucket, and ziptied the walbro on and plugged it in. Works good NA and on the nitrous

So whats the difference between the regular pump and the high pressure one? And do I need to replace the regulator too?

[97rs4life]

nothing needed with the regulator

high pressure flows more so if you run nitrous or power adder, you have enough fuel there and won't run lean

Ok, cool. So if I decide to get a high pressure pump now even though I dont plan to add nitrous for awhile, would that hurt my gas milage?
