Usually when using my diesel
heater the electric pump
will let off a thump every second or two to get fuel
into the carb/heater adjuster thing. The other night without warning the pump started cycling.
I figured that we must have been out of fuel
so went back and switched the tanks
and tried to bleed the fuel line. I first bled the filter, which the unit shares with the engine
, then I went right to the intake of the carb/heater adjuster thing cracked that nut and bled it until I got solid fuel...same thing, the pump was cycling. so I went and checked the tank and was 3/4 full.
So I must have an air leak somewhere that just randomly developed in my fuel line right? Strangely the heater is still getting fuel and working properly.
How do you bleed the air out of your unit? Has anyone had any similar occurrences? If so how did you fix it? On a brighter note the cycling of the pump is a lot less annoying than the thump thump of it when it is working properly, I am just trying to conserve electricity by not having the pump constantly cycling.
