Think outside, no box required.
Ahh mine was a 1996 X305 so had no twin tanks, just one massive 20gal one that lasted around 200mi if you used the loud pedal!Hi all, I can report all is back to normal, filled the tank and taken for a drive. Three stop and start procedures later the engine light has extinguished and full revs are available once more. That said I’m still going to sit down to trawl LZ and the wider web for answers. I had the 1980 Daimler fuel transfer valve issue on a past car but that was a simple fix, changed the valve. Not sure my SC will be so simple.
