Fuel pump woes

[keithf]

Where's the cheapest place to get a volvo/oem fuel pump, or has anyone got a spare they don't/won't need, stashed away somewhere?
Alternatively, what experience does anyone have of pattern part pump, will I get further with a volvo part?
Stealers want £250 for said part (though wouldn't tell me the brand), i've seen bosch pumps for £150, was bosch the oem?

Are you absolutely sure it is the fuel pump itself that is at fault? I would first replace the fuel pump relay (located under the fuse box cover) and see how you go from there (the part is £35ish from a dealer - a lot cheaper & easier to fit than the pump).

Apologies if you have already replaced the relay.

I'm pretty sure it's the pump, normally when I turn the ignition on I hear a very strong (I'm sure I feel the car vibrating sometimes!!) but quiet humming (the fuel pump), but since she broke down the noise is more like an "asthmatic" buzz!?!
I'm sure that if the pump fires/actuates (not sure on terminology) and pressures the system, then the relay must be fine?
I've seen replacement pumps to replace just the "pumping" part of the "fuel pump" (sorry thats the best description I can give!?!), I'd like to know if anybody thinks thats a good idea or should I just replace the whole thing?

Personally I would replace the relay first. Mine used to be quite audible on start-up but since I replaced the relay I can barely hear it (even standing outside!). Don't forget that the relay controls the pump so if the relay has gone then the pump won't work.

I'd hate to see you spend £250+ on a new pump if a £35 relay is the problem.

Good luck with it.

Easy way to check if the relay is the problem is to open it up and operate the contacts by hand.

If you decide the pump is faulty it may pay to extract the unit from the tank and have a look at the rubber connecting pipes as these can split and cause the problems your having.

I'd think a pump only fix would save you a lot of money.

I'm positive that its not the relay as the pump is buzzing, ie- the pump is being switched on by the relay.
I will check the pipes though before I shell out for said pump, that sounds feasible, thanks for the tip!

You could take out the pump assembly and look at the pump itself , but you would need one with the same or higher flow rate , It could be off the road for a week whilst you source one that will fit also the flap valve in the bottom of the tubular housing may be leaking , its best just to replace it thats why volvo only sell the whole unit , fit and forget for another 15 - 20 years :-)

Well, i've got the pump out and the rubber pipe was fine so it looks like i'll be replacing the pump.
The cheapest bosch (i'm assuming bosch was the oem) pump i've seen is from euro car parts, £150 all in, the cheapest complete unit (new) I saw was @ £400.........GULP.
Looks like i'm going to have to bend over and get my bum smacked!!
WAHAY.

UPDATE
Part number 0585 453 037 (the fuel pump I need) does not exist any more!?!?
I got one from euro car parts, it was different where the spring goes at the top (a little shoulder where the spring locates), then I ordered from Merlin motorsport, what arrived wasn't even close (different length and diameter)!?! What am I to do????
Does anyone (in the essex area) have a secondhand/used or new fuel pump lying around? I will collect asap and pay good money, but it must be the same part number as above.
Please help!!!! I miss my car!!! :-(

Maybe if you contact them they may be able to help with an in tank unit.
