Hi bare with me my first post. I have an outdoor Grant 90 combi. Unfortunately the oil delivery was late and the tank ran out. Done all the obvious things like check valve is on at the tank but don't seem to be getting oil through. I'm assuming it's gravity fed ( only single line in) so I should get a flow of oil if I disconnect the pipe ?.
If indeed the pipe is blocked can someone give some advice.
Cheers
Steve
