[Healeys] HD6 jets

[Michael Salter]

My experience has been that it very much depends upon the manufacturer.
When ethanol fuels were introduced in Canada we had a spate of diaphragm
failures which seemed to occur after the fillup with ethanol laced fuel. I
think the ones which failed were not genuine SU parts.
I did not experience diaphragm failures once ethanol resistant diaphragms
were installed but others may have encountered problems in recent years as
it's some time since I owned a Healey with HDs.
Looks like Trail Ridge Road in the Rocky Mountain National Park to me.
🤣🤣🤣
