Will a 97 gsr fuel pump fit into my 95 civic ex? I came across it and just bought. I plan on using it to run my 00 jdm itr. Will it pump enough fuel to the motor?

 

yes and yes.

the B series VTEC fuel pumps are different from non-vtec non B series pumps.
most likely because of redline being set higher and the effect on fuel consumption.

I dropped a '00 ITR pump into my 92 CX with zero trouble.

 

it will fit, although your stock fuel pump should be plenty...unless its not working 100%.
