Only appears to leak in the car, tried all the brackets but no leaks (chummy tank) even tried a bit of pressure but no leak. Any ideas.Douglas,I would give it a dose of modern ethanol resistant slosh sealant and put the tank back. The problem then can only be the cap or tap. Over here I use Redkote with success not sure of UK varieties. I suspect that stories of sealant degradation relate to older formulas breaking down in contact with current ethanol petrols.
I have an example of a much older installation from the UK which has turned stiff and cracked and flaked off, but I have had no such problems with Redkote seals I have done in the last 5 years.
I use whatever is cheapest petrol at the pump, including ethanol mixes. regards Russell
