Hi Justin.....I was just wondering how much you estimate it will cost to change gasoline tank. I just changed mine...the tank itself was $3,000 plus all the supplies to repair the cockpit cover. Thanks

....p.s. I cut open my old fiberglass tank and found the inside was blistering and starting to delaminate...fwiw.

Ken, What kind of tank did you get and where did you get it?

Ken, I estimated the cost of a new custom tank to be about $2500 and I would have to install it. I have not done this yet even though the gas in my area contains ethanol. I bought a $700 150gal "pillow" tank for the back of my pickup truck and drive about 10 miles to just over the boarder of north Carolina where it is ethanol free. Then proceed to fill up my boat with a rubber garden hose. It takes about 30 min to transfer the 150 gallons from my pickup truck to the boat by gravity. I figured with the higher gas prices at the docks, the amount I would save by filling it up on the street, It would pay for the tank in about 6 runs. I have used it about 10 times now and am going again tonight.

Just came across the reference to the CG requirements on gas anti-siphon & shut off valves. Note that this shows the owners tip referred to would only be good for diesel. Al "183.568 Anti-siphon protection. Each fuel line from the fuel tank to the fuel inlet connection on the carburetor must: (a) Be above the level of the tank top; or (b) Have an anti-siphon device or an electrically operated fuel stop valve: (1) At the tank withdrawal fitting; or (2) Installed so the line from the fuel tank is above the top of the tank; or (c) Provided that the fuel tank top is below the level of the carburetor inlet, be metallic fuel lines meeting the construction requirements of Sec. 183.538 or “USCG Type A1â€� hose, with one or two manual shutoff valves installed as follows: (1) Directly at the fuel tank connection arranged to be readily accessible for operation from outside the compartment, and (2) If the length of fuel line from the tank outlet to the engine inlet is greater than 12 feet, a manual shutoff valve shall be installed at the fuel inlet connection to the engine."

Very good information. I'd like to know where you find that kind of stuff.

Why did you have the tank shortened?
