Fuel pumps

[chris.richard]

What models do people with AR V6s use? Am I looking at £250 worth here?
:eek:

Secondhand Vauxhall pump from the scrapyard - £20.

Get it from any of the fuel-injected Vauxhaulls, Nova, Astra, Cavalier, Carlton, Omega. Took mine off a Cavalier, and I even took the bracket and re-used that.

I paid about £100 for a genuine, new A-R Bosch pump which is big and heavy and makes a lot of noise.

Out of interest does anyone know the price of a new Vauxhall pump?

I used a Bosch pump from a BMW, easily available from any Scrappy.

I took the Alfa pump, including the swirl pot, and buried the lot in the bottom of my left hand tank. Works just great! Does need a big hole cutting in the top to let the whole assemby in though!

I used a Bosch Jetronic roller pump (cos I had one from my Mini) (Don't ask).
3-litre 12V motor.
Capable of developing about 100 psi, which is well enough, but its flow volume you need, not the pressure.
This has worked fine for 11000 + miles so far, including track days, and doesn't weaken off at the top end (rollered a couple of times, no probs). I ran it in the Mini for a while before that, as well.
So its good for 210 BHP plus some spare, but no idea how much.

This pump comes with a rubber glove to keep the noise down. I mounted mine in an aluminium cradle, with a matching top half screwed down just hard enough to hold the rubber. Otherwise located by the hoses. Works fine, pretty much noise-free.

Thanks for the info Arthur! The reason I asked was that I intended putting a VDO fuel pressure gauge in the car during it's Pirelli conversion. I have a mechanical 30psi gauge and am researching an isolator system so I don't have pressurised fuel in the cockpit (!) but wasn't sure if the range was ok. I reckon that if I run the line from the isolator with a little air in it I will get a reading. It may not be accurate but it should be constantly inaccurate so any variation would indicate a problem!

The normal pressure (2->3.5 bar) is very similar to the oil pressure, so I used another of those nasty AR oil pressure senders tapped into the fuel feed. Avoids running fuel around the place and the signal can be sniffed to set a warning light.
