I've just been through the same thing re the fuel pump. Need a spare to carry for our trip away in September as the original pump is at 180k.
I spoke with Mario on the phone (he rang me after I placed an order via AULRO PM). He's 100% confident in these Lucas pumps.
There's an extra discount over the eBay price for AULRO members AND the pump also includes a new Mahle fuel filter (Mario stipulates that you MUST fit a new fuel filter when you install the new pump ... So he's including one) ... If you take off the price of a fuel filter, that makes the price of the pump sub $300 at AULRO prices. No brainier really 
I haven't installed it, it's a spare.
Don't see how you could go wrong with one of these. Price and after sales backup from a forum member !
