I am a little unfamiliar with walbro fuel pumps, are they specific for what car it is going in, or motor, or are they kind of universal. Does it plug right into the factory wire harness? I am thinking about buying a Walbro 255LPH fuel pump for my crx

 

i have one in my 95 and 97 civics (both swapped). they hooked right up no problem. i'm sure its proably the same on a 91. you might need to drop the tank.

 

Walbro FTW
