i heard that SI, GSR, and ITR fuel pumps are 135 LPH. And the sohc civics are all 79 LPH, but how do i tell the difference between them? are there any features which i could use to tell them apart? part number perhaps stamped on the side? if anything let me know, thanks.

 

anyone with any info out there???????????????????

 

I changed the stock one in my 92 VX with a 99 B18C1 pump when I did my swap. They looked identical once removed from the housing. I don't know how, or even if you could tell which was which after they are removed. Come to think of it, I might not even have a real GSR pump....
