whats a good aftermarket fuel pump to replace a stock one?

 

Just throw in an inline walbro and call it a day.

 

well i think the one in my denali is about to go out thats why i was wondering....and the zone a the other place doesnt sell them seperately..just as one piece

 

Is your truck an 03 or an 04+?

 

yeah i need to change out mine as well.

 

walbro 255 from what i hear, i have been told an easy way to get one but i havent done it yet

 

i have i didnt like it at all first you have to modify the canister in a shitty way second they are bad about haveing check valve problems from the get go i know first hand i would have to crank on it for several seconds for it to start i hated that !!!! get a stock replacement and put an inline pump unless your looking at a major build up and in that case put a sure enough fuel system in head to toe.

 

yeah unless you have plans for over 400HP just replace it with stock. Under 600hp put an inline on. All suggestions are for a return system.
