Amazing what some people will do to save time, then end up having to spend more time fixing the problem.

On a side issue with fuel, I often found slight leaks in the original sealant around the tops of Briggs fuel tanks. Over the years the seal tends to crack away and you end up with minor seepage around the joints. I use to clean the old seal as much as possible and then cover it with a neat layer of gasket paste and leave dry for a week or two to fully cure. All went well on the first two tanks I re-sealed in this way. But later on when I went to add more fuel I noticed some of the gasket paste had dissolved due to contact through tiny cracks and turned the fuel a dirty brown colour. I had wondered why the engines were getting harder to start and not running as good! So I had to flush out the tanks but even then it took ages before the gasket paste got hard enough to stop dissolving.

These days I only ever use polyweld to reseal these tanks. It cures fully in 24 hours and does not dissolve if it comes into contact with the fuel through a slight crack. It really works a treat and looks professional too. Re-seals the tops of these tanks for years to come.
