mossy Posted January 7, 2011 Posted January 7, 2011 Does anyone know how to get a big friggin dent out of a fuel tank? Quote
chris240 Posted January 7, 2011 Posted January 7, 2011 try borrowing a quality grade glass sucker from a glazier and try to pop it...but youll need a smooth surface for it to bite. cant you drill a small 5-6mm hole and insert a toggle-puller and then weld up the hole..whats that black washer hidding , is that the drain point ? Im sure it would be easier to just pick up a second hand one from one of the guys here edit...slide hammer, thats the word I was looking for ! Quote
Gordo Posted January 7, 2011 Posted January 7, 2011 Take it to a panel beater, he will have some good ideas. They can weld small tags onto the dent area and use a slide hammer to pull it out. Be sure the tank is full of water before you weld any thing!!!! But ask the panel beater guys they should be able to do it. Good luck. Quote
zzzzed Posted January 7, 2011 Posted January 7, 2011 us panel beater guys have tools called pin pullers that weld a stud or pin to the metal then a slide hammer is used to pull it out then the stud is snapped off after but!!! we dont like welding fuel tanks because even if it hasnt had fuel in it for years they can still go bang they can be either washed out with soapy water steam over and over again aor just filled with water to stop the bang but then the inside of the tank will need treating after to stop rusting Quote
Wayne G Posted January 7, 2011 Posted January 7, 2011 I have used air pressure before, a few psi, to pop dents in tanks out but be very careful or you will end up with long range tank. Quote
MickyG Posted January 7, 2011 Posted January 7, 2011 I have used air pressure before, a few psi, to pop dents in tanks out but be very careful or you will end up with long range tank. And no hands... This option is pretty dangerous - BUT - if you do have to try this at home, fill the tank with liquid before you put pressure on it. It can still go wrong but it'll be safer than compressed air only.

KatoKid Posted January 7, 2011 Posted January 7, 2011 Ive used carefully regulated air pressure to repair header pipes and expansion chambers on motorcycles. Generally 20 - 40 PSI will get the job, done you need to apply cherry red heat to the dent area. Same should work for tanks but you could probably only need 10 or so PSI, be sure to fill the majority with water first and also purge all fumes before heating with a rose tip. Quote
mossy Posted January 8, 2011 Author Posted January 8, 2011 Thanks for the replys but i think I might try and source another tank, I'm not keen on the air pressure trick in case I fook it up. Quote
Roes Posted February 2, 2011 Posted February 2, 2011 then the inside of the tank will need treating after to stop rusting zzzzed, what rust treatment would you use for the inside of a fuel tank. What do you think about using Rust Bullet? Quote
RLY240 Posted February 2, 2011 Posted February 2, 2011 You might find that the weight of water could be enough to push that back out with a bit of a shake (if you can lift 60kgs). Roger Quote
