Had a problem on a recent trip which came down to a fuelling issue.
It transpired my fuel pump strainer had disintegrated, and it appears to have sucked something up which fouled the fuel pressure regulator (its a manual device).
Struggled to find some parts, but came up with these.
Fuel pressure regulator. Can be found on ebay or amazon; cheapest from amazon
Fuel pump gauzes - again ebay or amazon. Cheapest on amazon (I'd ordered 6 from the states on ebay to bring the unit cost down, then found these
)
Note these only fit if the bottom of your fuel pump housing is intact, in which case you have to remove the lower plastic collar and slide these on. It's got a crimp type lug inside its collar.
If you fit a new pump from the kit below, you could fit one of their enclosed filters.
Fuel pump kit, incl pump, gauze, pressure regulator and Mahle filter. Ebay
They are actually sold for the C600/650, but the similar (but not identical) ones for the G650x series are £199 from the same supplier.
I've test fitted for size these parts, and they all fit. I've not test run them as I just swapped out my fuel system with a spare.
I'm going to carry the complete kit as a spare on long trips in future.
Some pics of what will and won't fit together are in the next post
