Facet fuel pumps and alternatives...

I have tried to repair thses types of pumps as fitted to my Austin Cambridge and Morris Oxford i must admit to not haveing much sucess they seam not to like being overhauled.

Sorry George

A Twin SU pump unit would suffice, unless you have injection.

They've normally got SU pumps which are dead easy to fix - and all the bits are available. You need the instructions to set them up properly, though.

Was the reason to fit it to try and get round fuel evaporation with the original mechanical pump, and does it do this?

Are you sure the problem was actually that the pump wouldn't operate? If the system is single line, then it is quite possible to get an air lock, the pump then just stops, giving it a whack might through kinetic energy get some fuel through, which is why it then goes for a little bit. When you got home did you try disconnecting the pipes and seeing if the pump then worked?? Having dismantled it, it may well have now died. Probably Burton performance would sell bits for it. If this problem recurs with a working pump, then you might like to consider fitting a fuel system with a return pipe to the tank, this can be done quite easily at the engine end, but a little ingenuity will be needed at the tank end.

The parts are also nearly as expensive as a new pump - I recall nearly £40 for the repair kit for an A40 electric pump.

In news: snipped-for-privacy@argonet.co.uk, Dave Plowman decided to enlighten our sheltered souls with a rant as follows

Oh dear, summers here and all the V8 P6's will be spotted on hard shoulders again...

I think next time I get one, I'll put an EFi lump in it..

It's some time since I've had to fix one, but don't remember the parts being anything like that dear. Besides, you can usually just fix what's wrong rather than get a complete overhaul kit.

The P6 already has a return line. Doesn't stop it suffering badly from vaporisation, though. It was one of the main reasons I got rid of mine.

My SD1 EFI isn't immune from fuel evaporation either. Leave it parked for about 20 minutes or so after it's got good and hot on a hot day and it won't start either. The trick is to put it in drive and turn the starter key for a minute or so - this forces the pump to run at full speed. It will then start on a few cylinders and gradually sort itself out. One thing I haven't tried is putting the A/C fans on a manual switch so I can run them as necessary. They will cut in without the AC running, but not often, or often enough.

About all you can do on an SU pump, is adjust the flip setting, or clean the filter and valve chamber. If the points are worn or the diaphragm is leaking, all you can do is replace them. Personally all I've ever replaced is the toggle and points assy. Never needed a diaphragm, gaskets or any other parts. Mike.

I've replaced valves. But as you say, a decent clean and adjustment usually gets them going again. But I've read older ones can have their 'soft' parts rotted by unleaded.
