Hi Chris.
See what Impex's reply is and take it from there since you've already approached them. Good luck, amigo!
I'm interested to know how you're getting on with your repairs.
Forgot to add: If you're replacing the fuel pump, do you have the part number of the fuel filter? If not, I can look it up for you.
I also replaced the fuel filter when I had the new fuel pump fitted. The old filter was clogged up as expected over time.
