My RR fell off the jack and an axle stand went straight through the bottom of the tank! Easy repaired with fibreglass but if you have joints or corrosion to repair that would be difficult. Fibreglass still OK after 6 years when I sold it. Draining a tank to remove all traces of petrol is a bit risky as petrol/air mix is extremely explosive, better to leave a bit in.

I've had a petrol tank out of a Cherokee via a syphon pump because it was full of crud. Left it a few days to air out before sealing and refitting. Should be ok once all vapour is gone and it's completely dried out.

Well its cracked the tank!! Front towards the prop. Has a formed shape and has a little crack!!! Will siphon it later so safe to drive home.
May as well sorn it as few other jobs to do like diff pinion seal and make exhaust more socially acceptable

I gas welded a petrol tank years ago. I drained it, rinsed it with paraffin then blew a hair dryer through it for a couple of hours before welding it.

No issues.

As for draining it, it reminds me of when I brimmed my diesel tank with petrol by mistake in the early days of ownership. Of course I only realised when the truck spluttered to a standstill miles from anywhere in the dark and pouring rain.

Had to let the lot go into the sub-base on the roadside, still grieves me to this day

 

[Gary820]

Found a uk supplier that does longranger products, waiting for a price on a bigger tank and if they can get one.

Turns out the filler has an anti siphon as can't get all the way into the tank so sender out to get some fuel out.

Bit of search on mud and seems to be a known issue with the tank cracking where it's formed!

If you decide to repair using heat, then an old trick to clear out petrol fumes is to drain in the normal way, then lay the tank opening against the exhaust of a running diesel engine, the diesel gases blowing into the tank not only dry it out but the mix makes the fuel vapour inert in about 20 minutes, it is safe to weld after that.

Thinking about repairs, there used to be a product that was a two part kit. A brown paste was painted over the crack or hole, then a white cloth was laid on top and then recoated with the brown 'stuff' which came in a glass jar. Worked great on a friend P100 after he drilled through the flat bed straight down into the top of the tank, can't remember the name, but petrol tank repairs are not that difficult and can be cheap compared to a replacement tank, these days all the tanks are plastic so repairs to metal tanks are rare.

My diesel breathes fresh air Haha, spotless tailpipe!!

It's a good tip.

I'm going to try and source a larger tank if I can, if not I'll have the tank out to fully assess if worth a repair or just get another standard tank. Could see the crack with the endoscope and it stopped leaking after dripping enough out! Workshop was a little smelly.

It was called Petro patch Dave, used it a few times in the past with great success, very easy and effective, moulding to any shape. When I looked some while ago to repair a Jerry can, it was no longer available.

 

[Michael Montgomery]

There plenty of products around Gary and first thoughts are a epoxy mix glue for cracks etc. Wielding is risky and a lot more involved to be concerned with.
Would be the first choice I would consider tbh.

THATS THE ONE!

Well remembered!

@Gary820 Something I would check while your in there, I had a leak from mine but only when brimmed, I know you have found the leak but check the filler and vent tubes where they are welded together, mine had rusted there, being diesel it was easy for me to Dremel cut the two pipes and put rubber fuel pipe connectors in, but it would not have been so easy had it been petrol.

I may have a picture somewhere but it was about 9 - 10 years ago?

Dervish, does that actually cope with fuel, it says from what I can see, 'tanks', that may be water.
Epoxy putty is good though for loads of things

Good stuff indeed, I've got two in the garage of a different make

 

[Gary820]

Well that was fun Haha.

Will run it to work for a couple of days as well below the crack now, when fuel light comes on will get the tank dropped for a decent look. Seems to be an issue on petrols on mud and few things I've found suggest its metal fatigue where it's formed!!

Hopefully will get a price for a bigger tank as if can get one fairly easily now's the time to do it. Even if takes a few weeks through the uk company I've been in contact with.

If it gets a repair it's a temporary repair for me tbh, I use it hard at times and unless it's a welding/braising repair I wouldn't rely on it as a permanent fix. If go used part the area will get re enforced before install.

@Dave 2000 already had a good look at the filler and I think it won't like being disturbed, can see it getting a hose replacement or a new filler.
We know that jobs like these always want more bits Haha.

Gary, you been keeping all those jerries in case there's a fuel shortage ?
They come in very handy in cases like those.

I drive a petrol there's always a shortage Haha.

I've got another 20 litre one too!
I used to have a track car with a small fuel cell and I help a mate when goes drag racing.

Yep, you don't really need a reason to have them except they are there when you want them.
I thought those gassers had factory option browser to tow behind ? Haha.
