Fueling issues

pooh · 02-04-2024, 11:53 PM

Has anybody had issues with fuel pressure dropping of on a M620 ie with a plastic tank? Internal tank pump and pressure regulator, I am having issues with water in the fuel, not sure how it’s getting in but on a sample of 1 litre I had 350ml of water when it settled. Apparently water don’t burn very well.

Any ideas Folks?

i’d start by checking the breather pipes are clear, if the filler neck one gets blocked water will get in round the cap. plastic thanks have a pair of screw in aluminium nipples for the breathers underneath, these are prone to getting blocked, i ran a small (1/8” ?) drill bit down the ones on the last plastic thank i had.
