What is the quietest electric fuel pump members have installed satisfactorily? Facet? FuelFlow? Webcon? I've tried 'search' but the posts it has thrown up are conflicting, i.e. some say Facet is quiet. Other say it is noisy. I've just had a Lucas fitted and turns out it is ridiculously noisy so I'll have to swap it over for a quieter one ... but not sure which to buy  |

Did the V8 have an option for a mechanical pump ? Cheers Colin |

Cheers Colin Yes, the P5B came with a mechanical pump but these pumps are now old and most are now clapped-out hence the switch to electrical. But some electrical pumps are obviously quieter than others plus there is the skill involved in knowing where to place, how to dampen the sound (mounting rubbers, sound proof foam) etc. |

I've also got a new spare so I will probably remain with a mechanical pump for my ownership.I certainly don't get any problems with fuel starvation etc. I kept the original AC pump as repair kits are available but sometimes the cam in the engine wears and the pump arm doesn't move enough to pump the fuel. At that stage, probably time to go electric as a rebuilt pump still wouldn't be effective. |

I have a Facet in the boot which makes a bit of noise when first switched on but I cannot hear it once the engine starts. There are many more noises to cover it up. I do like the fact that I can hear when I am running out of fuel as the pump becomes audible.

I use a Facet which is mounted on the Gearbox X member using existing mounting holes and a bespoke mounting bracket way below the petrol tank level so there is enough fuel left in the pipe to keep the pump primed, it is mounted on the Bobbins enigmas was referring to this keeps the noise to a minimum.
Mount the pump too high so it drains back and you will get the Ak Ak noise as the pump primes!

Mine same fitment as John's on x member but bigger pump and I drilled the member for bobbins.
Makes a noise under drivers seat as it primes then inaudible.
I bought mine from Wadhams as a kit but it would have been cheaper to have bought that pump on eBay where I was watching it already. Grrrr! - the days before pics but I did ring to ask what was included in kit. It is rated for front fitting so fine on the x member.
Priming takes about 1-2 secs after a lay up and has reduced the awful 20- 30 secs engine cranking on the old manual pump to about 3 or 4.
Best mod I made.

That long cranking after lay-ups did, unintentionally, have a benefit. It allowed the oil to be circulated and pressure to build before the engine fired and ran, usually at high revs as the chooke was out. When does most engine wear occur? Remind me?  |

I agree and it is an unintentional benefit of the mechanical pump. My oil warning light is usually out by the time the engine fires after a period of idleness. |

My method after a lay up is to disconnect the electric fuel pump and crank until the oil pressure is achieved |

So from what everyone's posted above ... by careful placement / tweaking it should be possible to install an electric fuel pump that does not create an almighty racket, audible over the engine noise - as mine (and a few others here) currently is. As the P5B was remarkably quiet in its time it seems a d**n shame to spoil the inner ambiance of the tickety-tock of the clock with the clakkety-clak of the pump |

I agree and it is an unintentional benefit of the mechanical pump. My oil warning light is usually out by the time the engine fires after a period of idleness. To clarify, a lay up for me might only be a couple of days to a week but starting is delayed and I usually let the engine crank for about 10/15 seconds, turn off the ignition and then turn it over again by which time it usually fires up. Gives the starter a bit of exercise as well  |

I can only hear occasionally my electric Facet installed at the front and low down on rubber mounts. No way can it be called a racket even when my hearing aid is at full gain  Its better than the tempermantal OEM mechanical pump that was a problem even when the cars were new |

My oil pressure light goes out as the engine fires so not too worried.
For me a layup will be several weeks or months anyway!

Sorry if this is mentioned elsewhere but 'Search' didn't throw up the answer for me. I'm about to replace my horrible, noisy Lucas electric fuel pump (mounted in the engine) but which Facet model do members most strongly recommend for reliability and quietness for the P5B. They obviously make quite a few models and I don't want to end up with one as noisy as the Lucas (such as the dreaded 'red-top'). Here is their Rover list but it seems to be just for the relatively modern ones ... www.fuelpumpsonline.co.uk/rover-fuel-pumps-2686-c.aspMany thanks for your guidance and a Happy New Year to forum members. |

I fitted an electronic pump from a V8 Sherpa van many years ago, unfortunately now unobtainable . Mounted under the car and very quiet.
Have a filter in front of the pump as it is usually muck that does them in and they should run at very low pressure
Strangely she still takes as long as she did with the mechanical pump to start from cold
