Hi Dutch,
Just been out in the -1C and had a look and No 2 is leaking like a good un.
At least it aint No. 5.
You know something - I am surprised that no-one has mentioned that little sod of a non returnable valve on top of the fuel filter.
I had air in the fuel pipes and it was the valve stuck open and allowing the fuel to drain back. This, of course, made the engine turn over without starting for about 30 to 120 seconds till the LP pump sucked the juice up. I often had a battery flatter than the flattest pancake EVER.
£13 from the stealer settled THAT.
Right - thanks for that - its the Bosch chappies on Monday.
