I went to put a new Walbro 255 in my 91 Si hatch because the one that was in there when I bought the car crapped out on me. Well, when I went to put it in I noticed the one in there was a GSS-342 which is for a 92-2000 civic, and the GSS-314 I bought for an 88-91 does not fit properly. I'm assuming they swapped the fuel pump and housing when they did the Z6 swap but dont know why. I just want to be sure the pump housing/bracket I have is the wrong one before I go and spend money on a new one for the 91.
