    Default Z22YH High Pressure Fuel Pump

    This is probably a stupid question but is there a facility in the UK for overhauling these pumps? You would think that they should be serviceable as most pumps are. Obviously a lot more to them than diaphrams and seals, but I cannot believe these are 'throw away' items

    I am in the Glasgow area, but I want to explore every avenue before I do an annual £500 pump and seal replacement.A complete and utter farce IMO

    No you cant recon them. However you can fit one yourself without any tech 2. A visit to a scrappy for an 08 write off would come in handy.

    I PM Dabbo. Sounds like the overhaul is 'do able' but this guy has his own machine shop. Not sure if the 'average' guy could do it. If I go sown the route of a replacement, I will definitely try stripping the old unit down and if it is servicable at all, I will add pics etc. This may be a while away though

    I work on mechanical pumps in my workplace (electronics industry !!). The pumps are completely different, but in my view, anything mechanical can be serviced to some degree. Interestingly I also found a place online that mailed me this explanation (not saying they definitely have the right pump, but I mailed them my details)

    QUOTE]John

    Plase supply me the exact pump number.

    Should we be talking the same number.

    We can supply new from Siemens for about £280 plus vat.

    Or (as many of our customers do) we can rebuild yours up to a higher standard, using updated parts, for about £350-375 plus vat, this pump will never go wrong.

    maybe just maybe, when you first pump broke up, the debris is still in the system, just fitting a new filter will not remove it from the system.

    Oh beware.... The GM network has a glut of the old type pumps, and they are selling them to unsuspecting vauxhall customers.

    Please send me the exact pump number, as there are a few varients, which will affect the exact cost.

    It may seem odd, that a rebuild pump is dearer than a new one, but trust me it will last.... We only sell this type of pump to our Defence contract buyers. We supply the AA with recon pumps for there vans, they choose this type after they run our of warranty pumps from the dealer.

    But for free advice, which ever pump you buy, make sure the system is clean, or you will buying injectors next time, and you'll get a shock at the prices of them.

    Clean tank.... clean pipes.... clean return valves.... clean manifold.... clean filter housing.... clean filler tube....

    Its good advice....
