While we are on the topic of fuel pumps ....
I recently installed a new SU electronic pump on my BJ8.
Relatively straight forward install.
However the "tick" interval was my concern.
Ticks approx. every 5 secs with the engine off.
Almost continuous when idling.
Very different to the old points style tick interval.
No delivery side fuel leaks.
Spent a lot of effort hunting for inlet side leaks - checking seals etc
Car runs fine.
Eventually gave up and called Bulen in the UK (where pump came from)
Evidently the electronic pumps have a ball bearing arrangement to simulate
the classic SU tick sound ?
They indicated all OK and just within spec.
Being cynical, still a little suspicious of potential  problems down the
line ?
So wondering what others have experienced when fitting electronic SU pumps ?
