Fuel tank rust repair

[Owl]

Run the exhauxt of you car into it for 30 minutes, that'll kill off any fumes.

Yep and never trust anyone's word that they've already done it! My old boss was caught this way and after he blew himself and mate across the workshop, he asked "I thought you said you'd de-fumed it", to which his mate replied "I did, I washed it out with thinners".

Oh, that's classy hahahahahah. I didn't know about it, I just filled it with water and welded the sucker up. Would've been much easier to use the exhaust trick, had I known the first time out...

I have just done my tank on a K5 GSXR. All I did was wait for the remaining fuel I couldn't get out to evaporate then with the fuel pump and the cap off put a bit of flame in the cap hole to burn out the fumes.. made a little puff but nothing spectacular

I've decided I like working on tanks now. Quite a challenge but rewarding when it goes (semi) ok

Hey man
howd u fix yours, weld ?
i just bought some JB weld of trademe to have a go at it. its a small hole i think. will pull the tank of on sat and sand it all back see what im dealing with

[prvoke]

Well JB Weld seems to have done the trick, its only been on for 3 days but no leaks since and not bad for a $16 investment and loads left.

No, it's something to do with the content of the fumes neutralising the crap in the tank.

No,it has something to do with no oxygen in exhaust fumes.

Heres some stuff called petseal that Ive used before and found it very good
Petseal Ultra Sealant.

All the below taken from this e-bay sellers page
http://cgi.ebay.co.uk/Petseal-Fuel-T...2%7C240%3A1318

The original and the best on the market!! Simply add the hardner and swill around the base of any tank to fill pin holes or stop loose rust from entering the fuel system. Comes in 260ml cans suitable for small to medium sized tanks, use two for large tanks.



This product with its advanced carbon fibre formula provides a corrosion resistant internal coating for all rusty and leaking petrol Aluminum,Plastic,Fibre tanks.


The two chemicals when mixed, can be poured into the offending fuel tank stopping small leaks and halting any corrosion already underway within the vessel. They then harden to provide a permanent seal.


The composite is designed to seep into the pitted surface and bind the rust into a smooth and corrosion-proof lining.

How to use petseal?

Remove the taps and block the holes.

Put a handful of nuts and bolts into the tank with a pint of petrol and shake it about. Drain off the petrol and repeat. Keep doing this until the petrol comes out clean. remove all the nuts and bolts and leave open to allow all of the petrol remaining to evaporate.

Mix all of the Petseal and pour into the tank. Keep moving the tank around to ensure all surfaces are covered. After a few minutes leave with any known leaky area downward. The Petseal should start to 'go Hard' after 15/20 minutes.
