thanks, good tip on the soap - hadn't heard about that before

Mat,
I know your a hunter and probably get into some rough places with your vehicle.

Here's another little tip for a fix for a leaking fuel tank that's good enough I patched my 25 gallon fuel tank instead of replacing or re-lining which costs around a $1000 dollars or more IF you can find reliable people that will work on it.

Get some of those stainless steel self-tapping sheet metal screws, about 1" long, in the biggest diameter you can find. Get some fuel resistant rubber gasket material they sell in small sheets at the auto parts store.
Also pick up a tube of gas resistant sealer there too.
Buy some flat washers that fit the self tapping screws.
Cut around patch out of the rubber gasket a little bigger than the flat washer. Cut a slit in center of gasket and push one of those screw thru. I made up a few I keep in tool box with the gasket sealer and a nut driver that fits the screw.

If you have a small puncture in tank, and fuel is leaking out, you apply gasket sealer liberally to rubber patch and drive the screw into hole and tighten down until the leak stops or at least is barely dripping.
I did my fuel tank in multiple spots and it's never leaked since. Often you'll hit something on road that will cause a small puncture but the tank is still good.
This and that soap trick is a good idea for people who motor off the beaten path.
