Re: Dickinson Newport diesel heater - no fuel flow
This is what I did with mine. Removing the clean-out plug was the trick. And I was surprised to find out how much carbon build up was in the bottom of the tube.
Hope this works for you.
Cleaning the Fuel Line
Any blockage in the fuel line from the oil-metering valve to the burner can
be cleaned by removing the clean-out plug situated directly under the burner.
The fuel lines themselves can be cleaned with compressed air or a pipe
cleaner or even blowing air through to remove any blockages. The plug then
must be replaced with tape sealant and checked for leaks. Tap the fuel line
once re-connected to clear any air locks.
