Hey everyone. Hoping I can get some help. So I'll start at the beginning. 2010 renegade 800r. Has 4600km recently at about 4000km had a fuel pump issue when I was out riding. I would crack the fuel cap and pressure would escape but as I cracked the cap the quad would die everytime until it built up a pound or so I'm guessing. Replaced the fuel pump seemed fine 50 psi fuel pressure the old one when tested came in at 38PSI. Two weeks after fuel pump replacement with the airtex pump had the fuel pump fuse blow 7.5 amp replaced with a 10 amp.... Been a few months lots of riding hundreds and hundreds of kms put on no issue...until today got down to half a tank thought I would crack the gas cap little pressure escaped and quad died stumbled and lost all rpm. Put cap on let pressure build up a little due to the factory can am check valve and ran fine. Got home cracked cap quad died. Put pressure tester in and read 50psi cap on or off went for a ride with it on couldn't get it to do it again. Stayed 50 psi ish entire time...now why in the hell do the few pounds from the hot gas fuming In the tank make it run or not....I could easily bypass the check valve and put a filter on the tank instead but it appears that it may leave me stranded If it can't build some pressure......at the end hear cant figure it out. Would appreciate any response. Thanks.
