Were the fuel filter
or are you going dirty
Wayne G said he still has to do that so it doesn't get in his way of doing other things .
What ratio of kero to Diesel ? & and how often do you mix the two & with the fuel pump is the fuel outlet the same end as the electrical connection?
10% kero minimum, these diesel heaters were designed to run in Europe on winter fuel that contains a fairly high ratio of kero, but 10% minimum will help stop the igniter and combustion chamber coking up. Anyone remember the old oil heaters that a lot of houses were fitted with? They ran on heating oil, a much more refined diesel product, if you tried to run them on diesel the whole heater would carbon/coke up and fail to function after a few tanks full requiring a complete strip down and decoke. These diesel heaters use a similar idea so they coke up on neat diesel.
Unfortunately the govt of the day got greedy and decided to tax heating oil and that was the end of that product, so a mix of kero and diesel is the next best thing. If it wasn't so expensive, running on neat kero would be the best option, but the cost is prohibitive.
I have heard of people buying up contaminated Jet A fuel, this is really well refined kero, once the water is separated it works well as a kero substitute at a much better price. I'm not endorsing this as a solution, just passing on the information.
