I got a walbro 255 fuel pump...it's the standard pressure pump...should I send it back and get the high pressure gss 340? I'm running stock heads, cam and injectors...have a trick flow intake manifold, adjustable fuel pressure regulator

Nope.

Why does everyone say the gss340? I do plan on doing heads cam and injectors in the future

unless you plan to force feed it, for just an h/c/i a 255lph will be fine...heck a 190 would probably do but since you have a return style system, 255 will be fine

Thanks guys!

What they are saying is with the 340 there is no coming back to the fuel pump for lack of fuel. but yes unless you are planning on many mods in the future and an aftermarket fuel line dia then the 255 will be plenty!
