Author Topic:   Pumping water from gas tank

Ray posted 03-20-2003 05:14 PM ET (US)
I am setting up to pump the water from the bottom of my gas tank and wondering if my tank has a baffle or two somewhere in the center or elsewhere. I have a 25" Revenge, 1985. The tank is spec'd as 140 gallons. I plan to use my electric fuel pump with soft copper tubing inserted down through a fuel pickup tube hole which I will remove to gain access to the tank. I will jack up the front of the trailer to convince to water to drain to the rear and direct the tube to the the rear bottom of the tank and pump until all the water is gone. How does this strategy sound to anybody who has tried this or something similar? Thanks for any reply.

Hi Ray, I did this same thing with my 22 Revenge. Since my tank was half full of fuel at the time, I lifted the bow and let it sit for a week in this position to allow as much water as possible to drain to the stern. Also I lifted the bow distinctively:ie I put a 4x4 under the jack stand and ran it all the way up. Rather than an electric pump I used copper tubing and a fuel priming bulb. I did have to move the pickup tube side to side to get all the water and I felt for the lowest points. I just kept pumping till I got no more water. Then I reconnected the plumbing and installed a Racor filter and Floscan. All told I would estimate that I got 2 pints of water and dirty fuel before I started pumping clean fuel... I felt better afterwards though!!! ;') Dave

Thanks Dave,
Sounds like I am on the right track. I added a racor last year and this is the reason I am now going to try and pump out the water. I have had so much collect in the racor. Please tell me more about the floscan, what is it and how does it work...
and how much $$$. Thanks,
Ray

Ray - A "Flo-scan" is the trade name of a fuel flow monitoring device. There are other brands out there but Flo-Scan was early to market and became a generic name.
The device has a transducer that is inserted in the fuel line and a electronic brain that provides various outputs such as fuel burn rate, fuel used both total and trip, fuel remaining, etc... The readout is typically a 2" round guage that you mount in your control pane.
As far as price, I just bought a Standard Horizon FF41 today for $183, with a $75 rebate. Flo-Scan brand can go upwards of $300.

I'd seperate the electric pump from the tank with a piece of synthetic hose of some type.
