Hi
Can anyone recommend a supplier and make of electric fuel pump for a rover p5b.
There was one fitted to the car and it has stopped working.
Thanks
Colin

A Facet id teh best option for fuel pump.
Type 'electric fuel pump' in to Search for a wealth of knowledge.

Hi, I have installed a German Hardi Pump No. 18812 in my P5B a couple of years ago. It harmonizes perfectly with fuel pressure requirements using a standard SU carburettor. The look is fairly old-fashioned too. Sometimes they are on Ebay UK too link. Most common on Ebay Germany though. Hardi is a supplier from Berlin for Volkswagen marine engines. If one needs help with translating please ask me: P5-Pump with bolt-on-fuel-lines in online-shop 9,90 EUR shipping to UK . They are on holiday until September. Mark |

That looks interesting - have you tried them. Are they noisy (the Facets are)  |

Yes it is also noisy due to it's massive casting. Compared to a small facet pump in my former MGB I would judge the noise as harder and louder. But the looks and feel rules that out for me. My Hardi pump is attached to the inner front n/s wing. I always wonder if I should try mounting it on rubber silencers as the mounting place possibly improves the exterior noise upon idle. But the noise is not quite stead, the tuc-tuc-tuc varies in frequency and loudness.
But it shows that it's alive ...
BTW the fuel deliverance is adaptive and you definitly need no fuel pressure regulator, as my MGB was in need of. Ther is no excess fuel spill from the fuel bowl chamber overflow lines, never. No smell even in prolonged ticking over before starting the engine. You just notice if the bowls are filled up and the engine is ready for start.

The last mentioned plastic pump is okay pressure wise. 5 PSI max is equivalent to 0,34 bar. Thats better (i.e. lower ) than a Facet I guess. Just in case the fuel bowl needle valves are a little worn ...

Yes it does look OK and the Facet is a piston pump - not sure about the German one though

Mine has a Repco-branded Facet under the floor near the reserve valve. It's quite noisy.
The best pump I've seen was a Japanese Mitsuba fitted to a Mazda in the mid '70s. A Mazda Capella I think it was. It was an improved copy of the old SU diaphragm pump. They solved the problem of the points by using transistors. It looks similar to the pump fitted on the chassis behind the LH rear wheel of early Range Rovers.

The Hardi pump is a diaphragm type pump and also replaces points by transistors. People using them in Diesel applications rate it more quiet and more reliable than a Facet here in Germany. Mitsuba is a pump brand many MG drivers like to use instead of the broken SU pump here in Germany. I just know the small Facet pump's noise from my old MGB. An adequate sized Facet pump for the P5(B) is possibly much louder if it works on pistons as described...

Mark,
Is that the same Hardi that makes agricultural pumps and orchard spraying equipment? That company's agricultural equipment is widely used and respected here.
The Facet is a little in-line short-stroke solenoid plunger that is pulsed back and forth rapidly by a pulsed magnetic coil. That's why it makes the constant ticking noise. The advantage of a diaphragm pump is that the diaphragm moves a larger volume per 'stroke' and the next stroke is only triggered when all of the previous 'dose' of fuel is consumed. Therefore its speed, and ticking, is proportional to the volume of fuel being consumed or returned down the bypass. If the carby isn't the bypass type, then it stops pumping when the bowl is full and only operates enough to keep it full.

I've just fitted a Webcon fuel pump, this pump is quieter than a facet pump, I have both pumps, fitted to the car, Webcon main pump, facet reserve pump, I removed the cable operated change over valve, and fitted two one way valves on the out put side of the fuel pumps, the advantage of this setup is you have a backup pump if one fails, bit over kill, but peace of mind.

This is described as being made of plastic, and for diesel engines. I wonder if it would be ethanol resistant, and suitable for current (and future) ethanol levels in petrol. |

No, it is for petrol and diesel. I have actually bought one as the pump on my car, which is working very well, has been on there for quite a few years. It looks good with 'in' one end and 'out' the other, so is easy to fit. It is also waterproof so can be fitted under the car. My view, which may be wrong, is that the lower the pump is fitted the better as it does not then have to pull the petrol up. The most important thing with any pump is to put an inline filter just before the inlet of the pump. I use the same as under the bonnet and change it at the same interval. Muck will destroy the pump.

Thanks for the confirmation. I'm thinking about fitting an electric pump to reduce/eliminate the amount of cranking necessary when the car has not been started for more than a couple of days.

True, that does happen but look on the bright side.At least a bit of oil is being circulated until the engine fires. I'd be very surprised if I ever need to fit an electric pump as I replaced the original AC mechanical one with a replacement supplied by the club and I also have a new spare.The one supplied by the club some years back is working well so must have been a decent substitute.I don't know why the supply dried up. Lack of demand I suppose. I assume that electrical pumps have to have some sort of cut out device in the event of an accident as I assume all modern cars have some sort of safety feature built in. |

Allan,
I had a similar problem with an early 1800cc Peugeot 504 many years ago. For some reason that I never worked out, the carby bowl would siphon itself empty when sitting. The petrol would siphon out the cold-start jet of the Solex carby, despite the little valve designed to prevent this. This meant more engine cranking was required before it fired when starting after sitting for more than a couple of hours.
The mechanical fuel pump was fine and didn't need to be replaced, so I fitted an old SU electric pump that I had lying around. I installed it between the tank and the original pump and wired it so that it only ran when I pressed a button under the dash. It was in effect just a priming pump. The valves of the mechanical pump would allow fuel to be pushed through it with little obstruction when not operating, and the electric pump's valves allowed fuel to be drawn through it when it wasn't running.
If your mechanical pump is OK, try fitting a Facet in this way. I'm fairly sure that it would offer minimal resistance to petrol being pulled through it when not operating. Others will know.
