I have a 92 Civic, and there is an 85% chance my fuel pump is bad because when I drive, power cuts of for about 3 seconds every 20 seconds,(feels like I let off the gas for 3 seconds when I didn't) and I already changed fuel filter, plugs, wires, cap, and rotor. What I'm going to do is get a Walbro after I do my B20 swap. The question is which one should I get the Walbro 190lph Fuel Pump, or the Walbro 255lph Fuel Pump. I will be going NA all the way with moderate mods. Also will these pumps make me burn more gas.

 

190LHP - the 255 will be overkill. The small one will support 300hp.

 

im sure you could still have the option of the 255 but youll need a fuel pressure regulator but i would only get the 255 if your looking at higher horse power numbers then 300

 

yah 190lph is more than ehough

 

agreed...make sure you dont get the HP (high pressure) version of either of those pumps
