petrol tank question
« on: November 26, 2009, 21:25:12 »
Hi,
       Please can anyone give some advice on the following, i am trying to remove one last nut from the in tank pump on my shogun, Ive tried everything its now all rounded.. Question would it be totally unsafe to  quickly grind it off with wet towels covering the tank to dampen any fumes.          The nut is  6mm. Please any advice even if its to tell me to forget it.. thanx rob

PETROL VAPOUR + GRINDER= explosion :shock:

Vapour is highly flammable.

you would need to fill the tank to the brim with water and then still leave it outside for a day or so before attempting to grind it; personally i wouldnt even then.

Do you have a death wish??

Could you not drill it out and then re-tap it?

Dont use an electric or battery drill, you would need to use a hand drill, and drill slowly keeping the bit cool.

Unless you can afford an intrinsicly safe drill, no sparks!!!

Is there enough showing of the head to cut a new slot for a screwdriver? again use a junior hacksaw and cut slow to keep the heat down.

If in doubt make sure the tank is empty then fill to the brim with water, it is the vapour which is most dangerous and highly explosive.

Personally i would go and get another tank, i dont think i would attempt it. If the tank is off you could try a local garage to remove the offending bolt, they would have the expertise to do it safely.

A half empty tank is a bomb waiting for some form of ignition to use as a detenator, a small spark is all it needs, and you wouldnt have to worry about getting the bolt out then.

If it was Diesel it would be less hazardous, I really cant emphasise enough how dangerous this could be and advise going down the professional garage route.

Hope this helps.

Don't be silly follow the first bit of advice, fill with water and allow to overflow then it is perfectly safe to grind, petrol isn't actually flammable it is only the vapour that is, we have welded tanks before with no issues!

Fill it with water and grind it. That's how you make propane bottles into wood stoves ;)
