I've got knee-sized dent in the top of my fuel tank. The paint itself hasn't cracked... although it's slightly bent.

Is there a simple way to get the dent out?

I've heard of people using suction or pressurising a tank to do that, but have not actually come across it.

Good luck

PLEASE PLEASE DO NOT USE AIR PRESSURE IN A FUEL TANK!! I once saw a Driver loose a finger with less than 4 PSI . Very dangerous with compressed Air on such a large surface area.

I've used compressed air twice to trygetting rid of a large dent. The first time it worked perfectly and the second it buckled the tank.
I've heard of big dents being pulled out with a suction cup but I've never seen it done. You could always have a go with a sink plunger if you've got one. It sounds like a daft idea but you never know until you try.

That does sound like a daft idea! But I've got nothing to lose in trying! (Don't expect it'll have enough suck but worth a bash... )

A friend of mine says that you if heat the metal you can then use like a screwdriver to gently pop it out... I've got a small blowtorch... but I'm not sure how I feel about putting it on my fuel tank

Make damned sure you've flushed *all* the fuel, *and* the vapour out of the fuel tank before you consider putting a blow-torch anywhere near the thing. Unless youre planning on using a small explosion to pop the thing back out again
(If so, see Wrinkly's warning about compressed air and double it...)

I you are gonna heat the tank with a blowtorch, don't forget to set the video running first, the £250 will help once you have demolished you garage/shed.

The best solution if you are welding a tank is to either fill it with water or an inert gas (nitrogen etc), then there is no oxygen present so there is no risk of fire/explosion.


Why don't you contact the people who advertise doing dent removal on cars Dent Wizard is one near us www.dentwizard.co.uk

Yeh, don't worry, I'm not intending to do that.

The local dent guy (of which there aren't many on a small island like Guernsey) wasn't interested.

Any of these any good?

Thanks - yeh, been trying eBay for ages now... I need a yellow one... they don't turn up very often and they're usually damaged

Removing dents in tanks is tricky, i have heard all maner of stories including the compressed air method, I have also heard of tanks splitting and buckling with the pressure.

I have looked into this in the past as it is some thing i come across quite a lot in my business, the only real solution that i found for dent removal was a weld system that tack welds small rods to the tank and you then use a slide hammer to gently tap/pull the dent out.

However, it is an expensive bit of kit and decided that it was not really a viable buy as the amount of fuel gained/lost in that small dented area would be so negligible that it is quicker, easier and more cost effective to use good ole filler.

Any decent sprayer should cover this for around £90/110.

Ace... thanks. Unfortunately for me the dent itself is really noticeable. Not only do I hate the sight of it but also if I ever tried to sell etc.

Anyway, apparently there is a dent expert over here so I'll see what they think.

You know what they say about experts......
