Hello,

My 6th (so called reliable) 200tdi Delphi lift pump has given up today, this one being just two months old. In most cases, the plunger has sheared away from the priming arm thus rendering the lift pump useless. On two occasions, the lift pump has also ****ed diesel into block, diluting my engine oil. I am now at the end of my rag with these ****e quality Delphi pumps and would like to try a more robust alternative. Does anybody know of a good alternative mechanical / electric lift pump that is up to the job?

Thanks,
-Tom

Its worth bringing to the attention of the manafacturer.

quality control/ using inferior materials.

We have but the response has not really been great. There have been other customers at my local landy specialists who have found similar problems with their Delphi lift pumps.

do you get them from the same place each time? could be batch issue, delphi are usually good and are OME!

Yes I have, but they replenish their stock on a daily basis and they only tend to keep a few lift pumps in at a time, so it's not like they have had a faulty batch sat on their shelves for a year+ I know that Delphi are supposed to be good, but I have had nothing but trouble.

you could try a genuine one should be cheaper than delphi

According to LRSeries, a genuine LR lift pump is over £100!!! I paid £25 for my Delphi pump about a year and a half ago and the garage have just straight swapped the damaged ones for new ones at no cost. Which one is the genuine LR part?

Thanks,
-Tom

So would I be right in thinking that the £8 Britpart pump is an OEM part? The last britpart pump I used pumped diesel into the sump rather than towards the fuel filter housing! I can't be so unlucky though :confused:

I have seen various different types of pump:

Style 1 (Don't know what brand)

Style 2 (Delphi)

Style 3 (Presume Britpart but price is high)

Which would you recomend?

Style 3 could be britpart. Thelast one ah bought came with all the fittings .. still got most of them;)
 
anyone whos bought these still got the fittings and the spacers block ? id be greatful if youd sell em to me .... i have a replacement delphi lift pump but it didnt come with spacers or fittings like the britpart one does.... im fitting it to a 19j and my original has the spacer machined into the pump !
 
i got through 3 lift pumps on my 200tdi in a couple of months, some britpart some bearmach i discovered the flange was to narrow on the lift pump, causing the arm to move to much on the cam and destroying themselves, i found a old genuine lift pump and the flange was 5mm thicker than the britpart/bearmach pumps, so i made up a 5mm spacer plate and another gasket fitted it, and job done this britpart pump as been on over two years and still going strong, i thought it was strange as i had to fit washers to the lift pump bolts to pack them out as they where bottoming out before the lift pump was tight against the block, obviously theres a manufacturing problem somewhere along the line
 
Pos - I'm racking my brains to think how - but is it possible that there's something else at play here that is damaging the lift pumps? One or two failures in a short space of time would be unlucky - but six! I just can't believe they've all been faulty.

It's a total pain in the arse. Here is how they have failed:

3 X Delphi - cam lever sheared from diaphragm lever
1 x Delphi - leaking diesel into sump
2 x Britpart - Failed to pump

There isn't really anything thats wrong with the engine - the problem would have to be with the cam lobe but it looks fine. I might go for another delphi, but spot weld the joint so that the join is more robust.

I've had many good years service from a Delphi pump, identical to the one you show.

Although your local guy only gets them in as he needs them, who's to say his supplier (or even the suppliers supplier) doesn't have a box of 20 sitting on his shelf and your getting the same batch each time, even over a long period? If you reckon the pumps are fine then you need to look at the situation.

It could be the pump maybe being over actuated, why I cannot be sure, and the Delphi design is such that it cannot cope, the others may have a fractionally longer pin on the diaphragm etc.

If the engine is run at high revs the cam lever will actually continue to travel up even once the cam is starting to drop, then it will slam down on the cam, this can lead to the early failure. Do you run it at high revs a lot? Do you change gears late?

When you mount the new one, push it up as high as you can get it to sit, so that the arm is not being pushed to near the full extent of its travel.

Or, fit an electric pump!

Benefits here, including increased security as you can immobolise the engine by hiding the pump connections away and making it difficult to rearrange the wiring quickly to bypass the ignition.
