I know this subject has been covered many times, but I'm still not sure what pump I should get.
The Facet pump seems a popular choice, but I'm worried that it may be too noisy. Is there
a quieter alternative ? If not, could the pump be mounted in the boot to dampen the noise ?

Tim you worrying needlessly!  Mount the pump lower than the tank...underneath the car if you like? They prefer to be gravity fed. Mount it on small rubber insulating blocks. You certainly won't hear it. They are extremely reliable and maintenance free. You'll wear out before it does. |

You can hear them ticking but not when driving. Even our Mk2 P5 with its boot mounted twin SU can be heard sometimes (in fact I let it prime before starting so listen to it)  and I am part deaf! |

Thanks chaps. I was worried that it would be intrusive at tick over or low speed.

Or you could use a 'transistorized' double-ended diaphragm pump from a pre-EFI Range Rover. Because they use a transistor to switch the current and the points on the diaphragm only trigger the transistor and don't carry the full current, you don't have the age-related reliability problems of the old SU pumps. Or there is the Japanese copy, by Mitsuba. Facet also make one for the Range Rover tinyurl.com/qh73ppzEdit: Can't find a Mitsuba. |

I have a Facet in the boot below the tank. I hear it when I switch on the ignition but not once the engine is running. Except, that is, when I am running out of fuel so I get a useful audio warning that the tank is empty and I only have what is left in the floats and pipes to go. This means I can find somewhere safe to pull over if I don't think I can get to a petrol station.

Thanks chaps. I was worried that it would be intrusive at tick over or low speed. I can hear my Facet priming Tim and when it's time to think of pulling the lever for reserve (this you will loose if you put the pump in the boot unless you want 2 pumps! plus it's too high!!) apart from that I don't hear it! mine is mounted on the gearbox X member on rubber bobbins after the reserve C/O. Pump plus reserve C/O  |

Yes John I will be doing the same (subject to copyright)  having brought another pump. I installed the Red facet in the engine bay. YUK. |

Thanks for all your advice. That has put my mind at rest.

The old Range Rover pumps weren't noisy and as the Facet appears to be a copy of it, I assumed it would function the same. I don't know what the original brand was. Was it an SU? |

Hi Warwick I don't believe it relates to S.U. You will find it in Rimmer Bros.
Its U.S.A made. Seemed right for me as it is O.K for engine bay fitment.

Facet pumps are totally different and even more reliable than SU's as they use a piston not a rubber diaphragm that modern fuels dissolve (still)
