Fuel pump

[Andrew S]

I fitted one of these replacement fuel pumps which do do have the points and it used to run constantly. I have a had a couple of moments over the weekend when booting it, it missed but just returned from an 70 mile motorway run in the fast lane and all was well.
Drove into the garage, turned engine off but kept ignition on and couldn’t hear the fuel pump as normal, it was quiet and intermittent pulse.
The pump is from a reliable supplier and is one of those black plastic bodied pumps.
Has anyone else had a problem with new pumps?

Mine has been fitted for over 12 years, 43,000 miles. Runs intermittently as it is supposed to do, as required to maintain fuel pressure. Has coped with many runs of over an hour at 70+.

Ok. It’s that I was under the impression that the pump continuously ran and did not stop and start as the original version. When from cold, the orig pump ran until carbs were needing fuel and then stop, but this one didn’t stop. Hence last night I couldn’t hear it and then heard a few pulses.
Will have another look later

I have one of those Andrew and it stops if there is no demand for fuel but starts up as soon as demand is there, just like the SU pump

Thanks Mike for confirming
