I bought a Spear & Jackson petrol hedgetrimmer from Argos and because I
don't have the receipt the 'help desk' won't help, even with advice. I
might be out of time anyway as they apply a 2year cut-off.

The problem is petrol leaks from the place where the petrol tube leaves
the tank to go to the engine. I tried surrounding it with bluetack but
the petrol dissolves this.

I wonder has anyone found a simple solution to this problem, or have a
sensible suggestion?

You will need an epoxy resin (such as Araldite or Isopon) to seal a hole
or crack where a solvent such as petrol can leak out. Remember that epoxy
resins will not stick to polythene or polypropylene, so if the tank if
made of one of these your seal will fail.

Make sure that all the petrol is out of the tank and tube, and allow
anything left to evaporate for 24 hours before applying the sealant. Allow
at least 48 hours for the sealant to cure properly before refilling with
petrol.

And do please remember an empty petrol tank is a lot more dangerous than a
full one, it's a bomb. Ensure there are no naked flames anywhere near and
do it all outside. Mechanics often fill empty tanks with water especially
if they have to weld anywhere near one.

Diesel tanks we do that with. With petrol tanks it's quicker and simpler to
feed the exhaust of a running engine into the tank to be welded. Dries it
out in seconds.
