Tracker 800sx water in fuel

[Mkike Des]

I have had my 800sx at the shop 3 times in one year. The first two it would not run their diagnosis was water in the fuel. The third time the unit stalled and a code of low oil pressure popped up. I checked the oil it was full. I brought it in for service again. They said there is water in the fuel again! They also said water in the fuel would cause the oil pressure sensor to malfunction. ( they must think I am a idiot! ) I have three other 4 wheelers of different years and I have never once had a issue with water in the fuel. I told them to figure out how water is getting in there. Its still under warranty. I am at a loss. Its 1 hour for me to bring the unit up there. I am regretting purchasing this unit! Has anyone else had this happen to them?

Have you personally tested for water in the fuel? to be sure the shop isn't BS'ing with you?

all you need is a clear container, siphon some fuel out of the tank into the container and let it sit about 10 minutes.... you will see a line form  (phase seperation) in the gasoline, on top will be gas and on bottom will be water (and  ethanol if you use E fuel)

Finding the entry point of the water shouldn't be too tough. Seems like a good job for a smoke test. Any qualified mechanic should have a smoke tester.

A vacuum test would be a bit harder, but you have to use what you have access to. And a smoke tester isn't something that most home mechanics  have laying around. However, with a little creativity, you can re-create the smoke tester using household items. And a cheap vacuum tester can be easily found online. 

My suspicion would lead me to the top of the fuel tank first. It would be the most likely place for water to get in. Next up, would be the return line, the cap, and the vent. A visual inspection of these likely areas might provide a quick solution, with no tools needed.

Let us know what the mechanic says. If he's unable, or unwilling to do a comprehensive test. You can do it yourself, with a little patience. It's very simple, and straightforward.

But as Travis said, first verify that there's actually water in there.
