how does selleys knead it react with pretrol? (gasoline for you americans)

i have a petrol tank that i need to put a fuel line in, but the hole for the fuel line is 5 times the size of the fuel line itself and for the life of me i couldn't find a rubber grommet to fit, so would selleys knead it work? the petrol wouldn't eat away at it or anything like that?

You could probably get away with the Selly's Knead/ epoxy putty. There are varieties sold that claim to be oil and solvent proof. I however have not personally used them, and the ones I have were not in your application. But I have used fuel tank patch repair kits. One place I worked used them fairly regularly as an easy method of stopping small leaks in tanks, both oil and fuel. And they make a lot of sense to me. This is one I found on Amazon:

Hope this helps. Good luck to you!

I think "Selly's Knead It" is a regional name, and also a brand name, for what other English speaking people call "epoxy putty"

I mention this since you were thoughtful enough to mention "petrol" is also called "gasoline".

It is more an australian brand but you are right.
If the right product is used it works great on tank and small engine repairs where not too much heat is involved (till about 150°C)

I used it on an old lawn mover that had a leaky tank.
Got a replacement tank later on but was too lazy to replace, so the old one is working now for 3 years with the plugged hole.
There are different varieties of the Knet it stuff, so use the one for metal repairs.
They say on the packing here to use gloves for the mixing and forming, do not do this as the stuff really sticks on the gloves better than anywhere else, use a brush and warm soapy water to clean the remaining goo off the fingers when done.
