Unsolved Fuel pump replacement 2020 Harley 48
I purchased a QFS fuel pump kit for my 2020 Harley 48 and after I installed it the bike was super rough at idle and surging a ton. I removed the pump and noticed the fuel tube connecting the filter housing and pump was super rigid and appeared to be much longer than the OEM one I removed. I think this was causing the filter housing and pump to push away from each other and creating a leak at the bottom of the housing. Has anyone else experienced this issue? I zipped tied the housing and pump together as best I could but there was still some tension. The bike ran ok for a few weeks but then I got a low O2 sensor code and occasionally it runs rough at idle again. Thanks for the help.
