my 92 prelude si needs a fuel pump, civic ones are cheap, can i use one? my stock pump is larger then the one i took out of my 96 civic but i replaced that with a evo pump that was also smaller so im guessing size doesn tmean it wont work?

 

I wouldnt see why not. If the plug mates up. I wouldnt use anything with a lower pump rate than stock

I have used integra pumps on my civic before, so ....
