Hi again, its been a while since I,ve posted here, but to recap I had a problem with my mk1 cab not starting after it had been off the road for a year, it turned out the fuel pump had seized, I bought another from a guy on e-bay, but when it arrived I noticed the body of the pump was a smaller diameter, the car starts and runs fine now, however the lift pump in the tank is noisey, I,m wondering if I need a lift pump to suit the replacement fuel pump, or is my original lift pump on the way out ?, I checked the rubber hose on the lift pump as I know these can rot, but it seems ok, any info appreciated, cheers.
