Water in the fuel

[Brad Henderson]

I am having a bad summer with water in my fuel, I have a 93 Pulse 185 with a 10 in JP.
I do not have a leak in my tank or I would have gas in my bilge water when I pump it.
I do not buy marina gas
I changed out the fuel gauge sensor and it does not see any water where it is
I have a full enclosed top on the boat
The cap is tight
I am wondering if the vent is somehow letting water in ?
I am getting real pi..ed off as it takes 1/2 an hour or so to pull the water out of the fuel each time it happens.
Any suggestion ?????

How much water are you seeing? How often do you run the boat?

install a water separating fuel filter kit - that'll help - where is the fuel vent located?

I had the same problem with my predictor and I actually toasted a powerhead because of it, I installed this tank vent http://www.westmarine.com/buy/products/14849-anti-siphon-tank-vent.html and no more problems. It's a great design, the only way water can get in is if you sink your boat. I tested in with a hose from all angles before i hooked the tank back up.

I premix my gas and oil and I run some stabil every tank, it will take care of any moisture that is caused by the ethanol.

As far as the water/fuel separating filter, I personally could take it or leave it. If you're getting enough water in there to cause a problem that filter isn't going to help much anyway, I know this from experience. it's good for pulling the moisture out of the fuel caused by ethanol and condensation. If you do go the water/fuel filter separator route I would rebuild your fuel pump or install an electric one. I had problems with 2 different 2.4's starving for fuel on the topend because the fuel pump couldn't pull enough fuel through that filter fast enough causing a loss of performance.
