Need help guys, changed the fuel filter, but the copper washer for the bottom line (from tank) did not line up right so it distorted the washer and leaked, took it off, went to parts store got another washer did it again, same thing. How the hell are you supposed to get that bottom washer to line up?

ok, apperantly it comes w/ a extra small copper washer for diff. applications, (CRV maybe). I took the washer out and put the original filter back on, tightened everything and no leaks. The weird thing is when I took it off there was a washer on that bottom line, it was all mashed up and blocking like 1/2 the flow through the filter, but was not leaking. Oh well, hopfully thats solves my lower then avg. MPG.

for 01-05 civic there is only one filter/strainer in the fuel tank where the pump is. its a 100k mile or more piece and only needs to be replaced if fuel pressure drops below spec. if you have a 98 civic, yours is prolly an external canister type in the engine bay towards the back.
