I'm working on the back axle on our Pearl, so have the rear jacked up quite high. The petrol tank has about 2 gallons in iit and is above the level of the petrol pump.
I now find that the pump is leaking petrol, probably from the top/bowl gaskets. I haven't investigated further until I can drop the rear again, as I don't want more petrol leaking everywhere.
Has anyone else experienced this problem? Is it the dreaded ethanol rot to the cork/rubber gaskets? Any other thoughts?

Could be as easy as a bit of something in the non return set up
I am always interested in any information about Rosengart details or current owners.

I think it would be fair to say that no leaks should appear unless the tank is above the carb, in the case of a Pearl fitted with a 26 va Carb the tank would be almost 45 degrees . In Martins case with probably a Nippy carb fitted even more. Back to first question , why is it leaking

If you cannot readily obtain or make the proper gasket, I have used O rings in AC pumps.
A pump which leaks petrol will also leak air and may operate erratically.
Very mnay pumps on other cars operate below petrol level. When disconnecting often convenient to raise the front high.
It is annoying but the classic unions, olives etc of older cars are vastly more prone to leak than the crude clamped tubing of moderns. Still not excuse to use on a vinatge.
