G300E Fuel System Parts
I've needed to change the fuel pumps (engine spluttering after 5 mins) on my G300E and thought that I would list here the part numbers of the pumps and related parts, in case it may be of use to anyone:
I have found an online retailer, based in Germany with good prices on OEM parts. They operate several almost identical websites with different names and with individual country versions. This one is AutoDoc (i've no connection, but the service has been good so far).

Picture below shows pump and filter package that lives under the left rear wheel arch liner. The brownish coating is wax from the factory. (Fuel Accumulator on left, Filter in middle, and Fuel Pump on right). The other fuel-pump is under the tank, behind the tank guard-plate.
