I am patching in the floor above the gas tank. The gas tank is a sealed containor and a spark can't get in. Do I need to remove the tank? Will heat cause a problem?

It's really to the sides of the tank and not really on the tank

 

I would be SO SO careful about this. Even if the tank is closed a slip or some fumes could go boom boom, and this wouldn't be no small boom either.

 

Be safe and take the extra Tim to remove the tank to avoid possible life long injuries.

 

Always have an extra Tim, he's awesome.

But yeah, for sure.

 

Play it safe and remove the tank.
Better Off Safe Then Sorry!!!

 

Seriously, I can't believe this question was even posted.

 

I think it's a legitimate question. The fuel system is a "contained system" for specifically this reason, among others. I'm sure that others have successfully done it without removing it, and/or done other work in the vacinity of the tank without issues. I just am a novice and want to make sure I cover all my bases. It's now on the list of "to do's".

 

If you don't post back soon, should we check the obituaries in the Pequannock newspaper?

 

I've welded right next to the tank before, if I wasn't in a rush I would have removed the tank, instead I put a damp, (NOT SOAKING) wet towel around/over the tank. Didn't catch it on fire that time. Still probably not the smartest thing to do though.

 

Cruiser 54 LOL! No, won't see me there this week thanks to all the great insight on here.....

 

Had to ask.... Glad to see you posted back!! LOL.

 

Remove the tank there are other ways to create spark within a fuel tank that is totally sealed from outside exposure, if you have a loose ground or frayed wire inside tank it could and will create spark worse case scenario is no fuel but vapor and or vapor trails which will ignite even by static electricity! if welding on a tank empty the tank fill with water and detergent(laundry soap) flush ,and fill with carbondioxcide from exhaust pipe of another vehicle make sure it is totally sealed and traped then make every precaution,to proceed repairing gas tanks.

 

It's a sealed system with a lot of plastic and rubber parts, lol. Get the wrong one hot and you'll have a leak that ignites. It is a good question. I'd avoid doing it.

 

I'm sure you are right that "others have done it". They say a picture is worth a thousand words:

 

Thanks for the great input everyone )
