Hi all, I've got a drip/gravity fed diesel heater (Force 10, now called Dickinson) that I've that I've never really got going properly (as compared to YouTube videos) It doesn't get that hot and doesn't burn efficiently (red flame). Yesterday I put some diesel in directly from a road garage and it almost took off! Does anyone know if these heaters have an issue with fuel sold in marinas/fuel boats in the UK? Like everyone else, got quite a big fuel tank so difficult to fill from a roadside garage. Cheers for any help.
