Thread: Fuel Tank Leak RRC 1992

Take it out and get it welded up !!!!
Are you saying that the Crack/hole is 2 inches below the main filler neck ? What happened , get a rock jammed in between the Chassis rail and the Tank ?

if its just a small hole you could screw in a stainless steel screw?

Either that or you can buy the putty stuff at supercheap

Take out the tank and weld or solder it. The main problem you'll have is finding someone that will touch it with a welder - as soon as you mention "fuel tank" it'll get treated like nitroglycerin. If you're handy with a welder, or better still an oxy torch, you can do it yourself quite easily. Drain the tank and remove it. If you want to be careful, leave it sitting overnight with detergent and water inside, flush it out next day, refill with water and weld or solder. Dry it out and reinstall it.

I know that everyone has a friend who had a friend who welded a fuel tank and it exploded and wiped out half a village, but if you're careful about it then it's quite safe. I am assuming a diesel tank of course. If it's petrol, don't touch it.

The putty stuff mentioned above works well - I've used it successfully delaying one repair by several years.

Fuel Tank and Radiator Service - Fuel*Tanks

We have had several fuel tanks repaired by this bloke, only thing is he's based at Northgate in Brisbane.

Alternatively why couldn't you fit a disco plastic tank?

Thanks guys for your various replies and usefull suggestions ..I neglected to mention that the Tank is plastic so welding is not an option......I think that I am going to have another stab at the Epoxy Putty route and see what happens.

I'll try and get some pictures up .......

Cheers

I have chucked away dozens of those plastic petrol tanks. I have never seen one fail. find a place that does gas conversions on landy's and see if they have one out the back.
Plastic welding is a recognised process too. Ask a crash repairer about plastic bumper bar welding.

You could try to plastic weld it using a zip tie as a rod with a heat gun.

I read about it and tried on the water tank of my camper which had worn through. The 1MM hole soon became a 20MM hole as the material was too thin from wear.
However if yours has cracked vs worn, then it could be successful.

If you are unsure to DIY there are plastic welders around that fix dashboards, motorcyccle fairings etc.

These tanks had a known problem subject of a recall in the USA, from cracking around the bosses of the tank vents in each corner.
Worth a try!!!
