my dispatch has started missing like theirs an air lock when it reaches temp.then when you get it up to about 40 mph it clears,its been into citreon for a diog and that says theres a hp fuel problem any ideas.
I take it the filter has been done,it may be worth removing the filter again and check for filings/metal particles which would indicate the pump breaking up,I think there was a problem with the fuel/hand primer on these also for drawing air but just guessing can end up costing you a lot of money
