Anyhow any idea on these bloody things? Been working fine until last night, diesel got run quite low yesterday so can only imagine the diesel has run back. In my head the night heater pickup should be shorter than the main fuel pickup so you cant burn yourself out overnight, and so shouldn’t really be able to pick any crap up.
Now all I get is about 7/8 flashes from the night heater switch and not kicking in, like it could do with bleeding if you will but I have no clue.
