Well, I'm an idiot. I got my bike all back together and was so excited to fire it up I think I put bad gas in it. Bike was hard to start, sputtered, coughed and died. I didn't realize I used my old gas can until after, and realized some water had probably made it's way in there. I obviously need to drain the tank, but I'm wondering if it's necessary to remove the pump assembly all over again to replace the filter. I'm hoping not because I already had to pull the pump assembly twice.
