I have a 99 Jag and I am wondering if anyone had ever heard of the gas tanks getting water in them from rain or splashover from the rear? 3 weeks ago I bought 40 gals of gas at a national chain that I use all time. In fact I have not put gas from anywhere else in 2 yrs. that I have owned the boat. The day after I bought the gas I fished 6 hours in the rain not hard rain but raining the whole time. Last Thurs. the water in the fuel filter light came on on my Opti. This was the first time I had been back on the water since the rain. Cleaned the filter and tried again Friday this time the motor quit running 1/2 mile from the ramp with the water light on again. Ended up pumping all the gas out and removing the pickup plates to clean out the tanks. I ended up with 15 gals of water in 50 gals that we pumped out. Did I get water when I bought gas or did the water get in some other way. Thanks for listening. Johnny

I would bet that you bought a little bit of water with that gas!

I use to own a Total station and when it would rain very hard for a long period of time we would get a lot of water in our underground fuel tanks. You may have gotten the water from the station. You can have them check the tanks with the measuring stick and they will put some orange jelly on the stick. It will change colors if there is water in there tank. We found water about 3-4 times in 3 1/2 years that we had the station. If it is in there tanks they can get it out real easily, they know how. If you just filled your boat with 50 gallons it may be from their tanks. If your tanks are full I dont see how you could get 15 gallons of water in them. The water would have to displace the gas and you would see gas on the water in the lake around your boat and you would probably smell it too. If your boat has been sitting for a while with just a 1/4 of a tank on each side you could get condensation in them, but 15 gallons is a lot of water. I have a jaguar myself and have never had a problem with my tanks. There will be other thoughts on this. this is just mine. About $55.00 for water, thats terrible.Last edited by customcityjim on May 23rd, 2008, 1:43 am, edited 1 time in total.

We have not seen that much water intrusion from operation. It has to be the station. When we see water from a fuel station it often has trash or an off color in that water. Check it well and let the station know.

Well I bought the gas at a Super Walmart and yes the water was orange or rusty colored. The first 5 gals I pumped out I let sit while we were getting the rest out of the 2 tanks. After it settled there was 3 gals of gas and 2 gals of water. Also the tank that I put 23 gals in had the most water and it was the tank I filled first. After we cleaned out the tanks, lines, the injector distributorand replaced the fuel filter , the motor ran great. Good idle and no flat spots all the way to 5750. Fished for 2 days with no problems but also it didnt rain. Johnny

It was the station and you will not be the only one to lodge a complaint. Though you need to in order for Murphy Oil to clean the water out of those tanks. The tanks were probably low on fuel andthatiz when this is most common or right after a fuel load when they were almost dry.

Thats terrible. If that ever happened to me, I think Id be lobbying hard for legislation to make stations install moisture alarms on their pumps.

Fried a 5.0 in a 89 Bronco years ago for that same reason. They had just filled their tanks when I drove up and got 15gal of gas and 18gals of water. It didnt show up till about 20 miles down the road but when it did it acted like I lost 2 cylinders. And like a dummy I kept going and didnt have it towed and fried 2 pistons. It happens usually when they fill their tanks. At the local stations I use for my boat and other toys, I know what days they get refills and I dont fill up on those days.

If they are filling the pumps I never buy gas at that station. I worked part time at a gas station and the people who would complain about water from our station were always when the tanks were being filled and stirring up the water that would otherwise sink to the bottom of the tanks.
