Keith,
Which SU fuel pump are we taking about? The one way valve discs Len
mentioned can be plastic or metal; depends on the model.
The pump will run faster than normal when there's a leak in the system.
It can be on the inlet, outlet, or internal.
As Bob said, if the pump stops clicking when sucking fuel from a bucket,
then you can rule out the internal and outlet leaks.
You checked the carb throats - they're dry?
Cheers,
Bob Haskell
