Fuel Pump Replacement

[TVRees]

Hi All,
The fuel pump has been playing up recently and I'm looking to replace it soon.
Does anyone have any thoughts, suggestions, experiences, etc. regarding some of the cheap aftermarket pumps which are avaialble online ?
e.g. fuel pump from eBay

Thanks. Tim
P.S. - I think this is the right replacement pump for the 2.9 S2 - if I'm wrong, please let me know

Not sure how you came up with that pump, might be right but search Capri 2.8 to be sure.

On the useful links page - alternative parts list - it says "Fuel Pump. Bosch Part No. 580254911".
The above links is for a Bosch Fuel Pump No: 0580254910 clone.

I suppose they are the same ??

What is it that suggests it is actually the pump that is faulty?

First, I did some research here, there was tons of useful stuff from lots of people.
Then, I did the following :

1. Removed the two connectors directly on the top of the fuel pump and gave them a good clean.
2. Connected a voltmeter, which showed 12V for 2 secs at the fuel pump imput connectors, after switching on ignition, but no pump movement.
3. Connected the pump directly to a spare 12V battery - still no pump movement.

Took the pump out today and tomorrow I will repeat 3. one more time. If nowt, then I think this original Bosch pump has gone to Bosch heaven after 26 years and 40 000 miles .

When I tried this earlier today, I thought I heard a quiet sort of "thunk" when I applied the 12V, but I'm not 100% sure. The pump was still fitted to the underside of the car and I was not too close to it.
Also, I only connected it for a few seconds, since I didn't want to fry anything, so there was no time for anything to get warm. More info. tomorrow, when I also plan to take off the bonnet and start some front side engine bay cleaning !

Yep, that does sound like a seized pump.
Does it make any noise when you apply 12v to it?
Does it get warm?

Checked the pump again today - really has gone to heaven !
After connecting to 12V, it made a single click and hummed quietly, but no pumping action !
Also, got a little warm after 2-3 mins @ 12V.
Next weekend, I will fit the replacement, a mid priced MEYLE aftermarket pump.

Thanks for the input and very useful ideas. One of my first thoughts was that the inside of the pump had been contaminated, possibly by rust, but everything was clean as a whistle !
Not a speck of rust anywhere to be seen and the inside of the pump (what I could see of it) was bright and shiny and looked like new.
Also, the 20L of fuel, which I emptied out of the tank, was nice and clean.

I was also thinking of an inline filter just after the tank, to avoid future problems. Do you think one of these will be OK ?



As you say, checking after a few hundred miles may point to some fuel tank rust. However, at the moment, I think this was just the "end of days" for this pump and hopefully not due to a more serious, hidden problem of a rusty tank.

Is a Bosch one that much more expensive? As above, you get what you pay for

The Bosch was approx. double the price of the Meyle. A friend of mine, who works as a mechanic, recommended the Meyle as a good quality pump.
