White smoke from diesel heater

In any case right now I'm just blowing off white smoke and not getting ignition.

My pump is a 5 kW (17,500 btu) unit. With half of the old floor stripped down to bare metal and no new insulation added, the heate is only able to raise the temperature inside the bus about 10° when the outside temperature is around 32° I think when I get some good insulation and tighten up some of the air leakage from the windows, two of these heaters will heat the bus pretty well. My only question now is whether they're reliable enough to be depended upon.

I rented my bus to a couple that was in a house fire. He added 2" of foam every we could and then the 5KW Chinese heater. They are still learning the fan and fuel pump ratios but they love it.

2 teaspoons per night of diesel per night!

I think you aren't getting enough fuel. YOUTUBE is your friend.

You can have bubbles on the pump inlet side. We got green 3/16 as well. still running the 3/16 but a very short run. Having trouble finding 2mm hard nylon line.
These pumps only pump 0.02 millimeters per pulse= 250 pulses per teaspoon!

Pulse rate on startup should be high like 7-8. Mine only goes to 5.5 but really puts out heat and fan is a real fan.

You can use your sunroom in your house in the winter with one.
