I am swapping a D15B VTEC into my CRX Si... And I noticed that the hose that plugs into the FPR is a tad bigger than the nipple on the FPR... I was just wondering, a few things... Whats the best way to correct this? Use my stock FPR? Change the hose size? Also is this just a vacuum hose, or does the fuel actually travel thru it? Just worried about possible leaking, since its right above my alternator (which will spark if fluid drips on it)...

Thanks!

 

The hose on top of the FPR is just for vacuum. Its impossible for fuel to get in there. The hose on the bottom is the fuel return line. Make sure that is tightly on the FPR to avoid leaks. I would just change the pipe if it doesnt fit it wont make a difference to the vacuum reading. Or just make an adaptor??
