Transfer tank leak

[Stan R]

Got a very small hole in the bottom edge of a transfer tank

What is the best way to fix.

Weld or use one of the fix it kits.

Steel, or aluminum?

I chipped the paint off. It looked like it was hit?

Is it a fuel transfer tank? Pressurized? Is the hole on the top, bottom?

[bboswell]

I would weld it but I’m sure the epoxy fuel tank repair stuff will work too

Yes fuel tank that hold diesel for my tractor

Bottom edge not pressurized

It's one of these.

I wouldn’t weld on that if it’s had diesel in it - some will tell you they’ve done it by purging the tank with CO2, dry ice, etc. but they’ve just been lucky. I’d try to line the tank or use some kind of epoxy if you want to try and save it.

...just not worth the risk in my opinion to grind/weld. For your safety I’d buy a new tank for $300 and move on.

Already bought a new tank.

They make this kit and might work? do have to sand the paint off...

I don’t know anything about that stuff but everything I’ve used from Devcon has been great stuff.

I’d wire brush the area by hand - if the hole is small and you’re confident it’s rust free it might just work.

I already got the kit and will try it once I get the tank emptied.

Your confusing diesel with gas.

Your confusing diesel with gas.

No Sir, I’m not. The auto ignition point of diesel is around 400 degrees F at atmospheric pressure. I’ve seen plenty of guys put out cigarettes and other flames in diesel but that’s no where near the auto ignition temperature.

Welding could easily heat up the fluid to 400 degrees F and ignite said fuel.

Like I said I know lots of guys have welded on diesel tanks and lived to tell the story - but it’s not worth the risk.

Edit: For those who are really interested in this - google "flash point" and read up on that. Then google "auto ignition". It's different mechanisms of combustible stuff catching on fire.

Do not weld on a tank that had diesel in it. Makes for a hell of a explosion!!!!!!

[Stan R]

The auto ignition for gas is higher than diesel.

Diesel 410 F

Gasoline 536 F

You would have thought it would be opposite.
