Im with the other lads..'proper' dealers are sposed to replace this and inevtiably (some) dont most of the time
The T8 is reknowned for having a struggling fuel pump due to clogged filters.
Worst case.if you do need a fuel pump then I do have a brand new one here with some special discount for a man of taste like yourself !!! The part number is 43040041A, and its marked up '996/M900'..not sure if they are generic but the offers there if it will fit ..? Nelly/Kev..any ideas
Cheers
Nat
