Hello all, looking for a bit of advice, maybe you have done this yourself? I recently read somewhere that someone put a petrol tank under their drivers seat to replace their leaky tank, because i have the same problem i was considering this instead of welding my original tank. Is this possible? and what bits would i need to do it? Im new to landrovers still so any advice would be greatly appreciated! :confused:
 
No-one I know would risk trying to weld a fuel tank, the chance of explosion is too great. Even if you wash it, there is still enough fuel trapped in the seams to do serious harm.

Click to expand...

it depends how much repair work is needed - I've welded plates on split tanks before

empty it, let it vent for a few days and if you'r really H&S obsessed fill it with water first
 
The tank just seems a funny shape in comparison with any diagrams ive seen, and ive been unable to match it up with any of them, hence me considering welding it. My Landrover is a series 2a 109, registered in 1970. Does anyone know where i can get a new tank because believe me id rather replace it than weld it, that would be a very last resort as im fully aware of the risks.....
 
Suggest you may as well remove the tank and find the leak. If it is badly corroded get a new one.
If not fix consider fixing it.
Mine had a leak which turned out to be only a tiny pin hole. Cleaned it up well and sealed the hole with solder as too small to bother with welding. Pressure tested it and it was OK. Covered repaired area with a little plastic metal to give it more strength.
Been fine ever since.
Good luck.

I think it may well be leaking from one of the seams, i havent actually removed it as of yet because im actually being a bit cautious for once and seeking advice first! Ive got to cut the bracing bars off of the drop plate first because they go under the tank impeding any removal of the tank in a 'friendly' way! It would have been an easy job if they were bolted instead. Ive posted some pics of my landrover in the gallery under 'Nick the new bloke's Landrover if you want to see the old girl...
 
Sounds awkward!
Mine is a SWB with the tank under the drivers seat. It still has to come out below. Its held up with a retaining strap which is bolted up at rear.
Nothing to be cut(apart from ceased bolt!)
Whether you fix it or replace it, it still has to come out - just thought it made sense to acurately diagnose damage before deciding course of action.?
Cheers,
Steve
 
Thanks Steve, i agree that itll have to come out anyway, i guess i'll just have to weld the bars back in so i think keeping the welder away is near impossible....Until it comes out i havent got a scooby doo but i'll soon find out.
 
Welding seams is quite difficult, you'd have to weld right round to make sure.
If you cant afford a new tank, as a temporary measure you could have a look round some breakers for a tank off another vehicle that might fit, ford pickups have a nice square tank.
 
My tank was leaking last year... I toyed with the idea of patching up the old one... but they are quite cheap to buy new.. under 50 quid (pattern part). Saves a lot of time and hassle patching a rotted one... and before fitting, I painted it with a thick coat of Hammerite with rust inhibitor built in.
 
Leak Fixed! When i took the tank out, i noticed that along the seams was some sort of what i can only describe as silicone sealer, so with some new petrol resistant sealer applied and a quick leak test its all good! (for now anyway, til i can scrape the pennies together for a new one) Thanks everyone.
 
yeah aparently , me mate did it on his 110, just keep rubbing till it gets a good coat of "filler" over the hole then yer ok ,

i rather weld it me self, ;)
 
Well, next time i go playing in the pit or something i'll take the soap i think! Good for emergencies i reckon......easier to carry about than the welder! You right though, welding for the long term....
