Fuel tanks

[kevin powles]

Hi, Finished one of Bens made tanks today, Can't tell it from an Original .

Just a note for those finishing them, remember to blow through the vent pipes after soldering, also go easy on tapping out the pick up fitting holding screw holes, I broke a tap.

Used POR fuel tank sealer, works great, stops rust, follow the prep process before applying, be careful to blow through the vent lines, apply with drain plug and pick up line removed.

Thanks Ben,

Glad they worked out OK.

Everyone who wanted them is aware and collection/delivery is being arranged.

Brian Asbury had spare drain bungs, caps and pickups. I can get the castings made if others want to make their own.

Kev, did you just pour the solution into the tank and tip the tank to coat the surface ?

I was thinking of taking mine to a local galving firm but that would be cheating.... And expensive

Hi Rich, Etch prime and clean the internals for a few days, Put the Por 15 in, make up a blank for the take up flange, bung the ends of the vent pipes, put in the drain plug and rotate the tanks, every which way, I figured attaching to a 'childs swing' would work best, gives the kids something to do aswell!.

remove cap and blank, vent bungs, and drain plug allow excess to drain, overnight is best, keep blowing through the vent lines, avoid 'puddling' in the tank, so keep checking on it.

clean up the filler cap before the por drys.

I figured getting them galvanised, would be costly and weather you could do this due to the soldered joints, can anyone comment?.

rich, you coming to war and peace?.

Never thought about the soldered joints... Yes I should be there again this year, I need to touch base with Shaun and book my room ;-) also need to sort logistics etc etc. busy selling stuff to pay for rail tickets etc :-) just found a pair of original front fenders which will be going into the for sale section shortly.

POR has failed over time with several of my MV friends. The white teflon separates and the film gums up the tubes.

I have used a newer product called "Red Kote" -http://damonq.com/red-kote.html
RED-KOTE®
Red-Kote is an internal fuel tank liner designed to seal leaks and prevent further rusting. As a sealant, Red-Kote excels at sealing the often hundreds of pin-hole leaks that occur along seams or where straps wrap around the tank. Once in place, Red-Kote forms a very tough, flexible membrane that will never crack or flake as many competitive products do. Red-Kote will not plug lines or cause engine damage when used properly. Future rust will be prevented because condensation will not contact the metal. A partial list of additives that Red-Kote is resistant to includes ethyl alcohol, methyl alcohol, toluene, methyl tertiary butyl ether, isopropyl alcohol and tetraethyl lead. Red-Kote takes approximately eight hours to dry. Packaged nine quarts per case or single gallons.

I have used this on a Dingo and the Humber main and aux tanks and not problems yet.

Hi Jim

Failure of Gas Tank Sealants in the US often related to our E10 gasoline. Jim raises a very good point about the white gas tank sealant as sold by Por 15 and others, having been observed to fail do to the age of the tank sealant and introduction of Ethanol containing fuel sold in the US are at least anecdotally responsible for fuel tank sealant failure.

I wonder how often these failures are the result of a less than perfect treatment of the tank or a tank design that just did not let the coating cover every surface in the tank evenly?

Jim how long as the RED-KOTE® been in the tanks you mention?

Cheers Phil
