Yeah
My fuel tank has got pin holes on it does anyone know of someone that is brave enough to repair a fuel tank or a specialist. Unfortunatly a new fuel tank is pretty much unabtainable.

I'm welding a couple of pinholes in a fuel tank as soon as I've finished my cuppa. I think I'll be fine as I havnt had any petrol in it for 6 months.
I have used plastic padding leak fix before to do a tempory repair to a petrol tank as I couldnt be bothered changing the tank in winter, and the repair lasted for 6 months until I changed the tank. if you then had it replapared later, they'd need to cut the pin holed section out and let some new metal in

I've seen it done by filling the tank with water and then (carefully) MIG-ing. Welding anything wet isn't easy, as anyone who's tried to weld a car outside when it's been raining not too long before will know.
As you can probably imagine, I'm not suggesting that you try this at home! It's really only for someone who really does know what they're doing.
The established way of repairing a steel fuel tank though is to get it steamed out first. You'll be able to find a specialist who can do this for you.
But I'd try Chemical Metal / Petro Patch first and only resort to welding if you really can't get it to stop leaking.
But don't worry, there will be a solution!

How big are the holes? I've used this in the past with good results.

When I've been working on Quarries, the specialists come when the tank is full of fuel and weld it then.
It's not the fluid that's flammable, it's the vapour.

I'm sure you know what you are doing - but it is best to tread carefully.

Empty it out as much as possible, leave it for a few days to vent then blast a CO2 fire extinguisher down the neck before welding. Filling it with CO2 should prevent any big bangs.
I pressure washed the tank on my Pony very thougroughly before attempting the weld it and that was no problem. It was really shagged with hundreds of pin holes. I welded up about 60 of the worst ones then used an epoxy sealer to treat the rest from the inside. I used black Por15 on the outside ( 2 coats) followed by some Por15 'Tie Coat Primer' then after all that had hardened, I rubbed it down to key it and whacked a few thick coats of black 2k on. It's never leaked since.

I have a different approach I've used before, last time on a splitsrceen camper fuel tank.. I filled it full off water, used an air hacksaw and cut along the seem until it was in 2.. then I just cleaned well & treated, repaired everywhere it needed to be, then welded the 2 half's back together, whole process had taken about 4 hours, I then refilled with water to check for leaks, job done, safest way I could think of?..

couple of suggestions a way of making the tank safe would be connect to the exhaust of a running engine to fill it with non flamable fumes give the tank a good clean to make sure that there is just the one pinhole and not a piece of lace held together with muck i once heard a quick fix can be made by rubbing a bar of soap into the hole how about soldering the tank finally i have fixed a tank using araldite ttfn glenn

I have repaired loads of Porsche 356 tanks, best way is to hose it out with water, keep that thing in there for a good half hour, drain it right down, plug up any breathers and fuel take offs but leave the filler neck open!! Fill if back up with water, just below where the holes are then use normal electrical or plumbers solder and a plumbers torch to seal them up!! Oh, and make sure the filler neck is facing away from you!! Have you not tried Pete 33 Grinder on here? Him and his mate Matt have loads of new and used Daf parts, I think Matt has just broke up a 66, should have the same tank...

unfortunalty its the triumph tank not the DAFs which is an awkward shape. When the car was built it was sat on 2 felt strips to stop it rubbing holes in the tank. Which was all very well except that at some point in its 40 odd years the boot has leaked or been left open. The result they soak up and hold the water like a sponge and are in permanent contact with the tank Would it be safe to do away with them or am I going to have to put some strips of carpet or similar to replace where theyve rotted away

It's not the fluid that's flammable, it's the vapour. yes but that will be diesel not petrol, totaly differant ball game you try setting light to diesel vapours (if you can find some that is) petrol vapours at -43C wereas diesel it's about 60C, drop a match into a petrol tank it's good by drop a match into diesel it goes out ;D just get the tank steam cleaned, a valeters will do it for a drink
