Collapsible Fuel Tank

[Guest]

Thinking of replacing 5 gallon metal fuel tank with larger volume collapsible tank under aft berth.

Got any opinions, recommendations etc.?

Fitted on this year by hanging it alongside the hull under the cockpit locker floor. Cirtainly the job was much easier than fitting a new rigid tank. Having a wooden hull I was concerned about condensation under the tank so fitted slats to the frames for the tank to rest on - improtant to stop abraision. I used nice soft spruce. The only problem has been that the unions wept a little, so put them where you can get at to tighten. I didn't and am waiting till I have used up the fuel to tighten the bottem one! I think lack of water in fuel is a significant plus - as there is now air above the fuel there is no wet air so no condensation. Interesting to see if this is the case over the first winter.

If yours is a petrol engined boat then I know of no manufacturer that makes what you want. They are I believe all designed for diesel only, don't be tempted to use for petrol, it could prove to be extremely dangerous!

Have you considered a rigid plastic fuel tank? No personal experience, but they can be made to fit almost any available space. See adverts in mags.
I have an inflatable water tank from Plastimo. This is my second and I expect at least six years life. Abrasion seems to be a problem unless very carefully thought out.
