[Mgs] Fuel Pump?

[PaulHunt73]

AFAIK Facet click away all the time unlike the SU design which only clicks on demand.  There are Hardi types which look exactly like the SU, and plastic-bodied Moprod which do not look the same but mount and connect in the same way and operate like an SU.

Both those, and the later SUs, are 'pointless'  pumps and I've had problems with the Moprod where it started short-stroking and causing fuel starvation even though it was clicking away, and I just had to wait until it decided to start working properly again.  After two or three bouts of that I junked it and fitted a pukka SU - with points, at least with those a clout usually gets them going again.

What filters there are from the factory are internal on HS cars - tank pickup and inside the pump, HIF cars have one just before the carbs.

I don't think dropping the tank will show much, although if you drain enough out and remove the gauge sender and tip it on end you may be able to see the pickup - if there are no baffles.

  After a cursory inspection today I found a non SU type electric pump.  Looks like a large Facet type, but I can't be sure.  I also found that there are no filters anywhere between the tank to the Weber.  I removed the cylindrical mesh filter in the Weber and it was absolutely clean.  So I started it up cold and for the first time right after start it idled a little over 500 rpm.  Usually with the jets (probably wrong ones) in the Weber startups have not been under 1000 rpm at idle in the past.  The pump was clicking away as normal.  It has rubber type fuel hose on either side of the pump which should not present a problem.  Don't want to, but might have to drop the fuel tank and have a look see.
