Hey guys, I haven’t had the problem yet but seen where other people have and how it could be an issue. I just bought a 20’ 700 EPS. I’ve seen where the vent for the fuel tank that runs down the rear A-Arms seems fairly low as well as hearing some guys say that they have picked up water into the tank on a hot day crossing a creek and the rapid cooling has caused a vacuum on the vent and brought water back into the tank. Has anyone come up with a way to prevent this? Heard some guys add a inline fuel line filter and cut the tube shorter and some put a ball check valve in. Opinions?? Thanks guys!
