Hi Vitesse,
I have spent days (!) searching the market for spare parts. Often, I have found nothing or no reference due to the fact that neither MG and in my case Hoborn/Eaton no longer are in business.
In the end I found that a gasket kit to a "FORD Transit (early 2000?)", that I believed would fit by the look of it. It turned out to be ok but not the oil seal that was in NBR. The original is made of flour rubber/FBR, so had to buy them separately (a separate hassle).
I ordered a "test" kit from a Italian company and paid a lot, including shipping. When I actually had the kit in my hand and could see some numbers, I started to search again and found that Meat & Doria was the producer. More searching and I found that I could buy the same kit on Autodoc.se or similar, for a third of the price I had paid. Now I know!
The parts are (to my pumps)!
Meat & Doria part # 37079 (Ford Transit)

BUT I think below would be more suitable for my pumps and cheaper!
Meat & Doria part # 37041 (Land Rover Discovery II)

If I would add a thought, it would be that may spare parts and PAS are as I cvan see exactly the same, even if given different model and part numbers. For example, the two pumps I have (QVB101411 = HE 1205095/14 and QVB000280 = HE 1205095/22) are to me exactly the same (have dismantled both into pieces). I cannot find any difference between them.
I can also add that I was surprised that so many leads ended up to be one of Victor Reinz over 400 companies dealing with auto parts. I had never heard of them before this journey.
That´s it / Nils
