ThermoPride Oil Heater. In December after moving in and purchasing diesel fuel, had to restart the furnace. Called a technician and watched him restart it. Seemed pretty simple, basically just let it run for a few minutes with the fuel running aerated through the Tiger Loop De-Aerator, occasionally wiping fuel off the top that sputtered out and then the fuel came through finally with no air. Went through 900$ of diesel in about 3 months (time to get a new heating system) and ran out of fuel, only way to check it is with a dipstick like a caveman (I'm learning I'm not a fan of oil heaters).

Anyways, purchased another $300 of fuel and tried to repeat what the technician did. Tried a few rounds of running aerated fuel for the 1 min. cycle then 40 sec wait time on igniter. Still full of air. Tried pulling the sensor out and shining a light on it to trick it to keep pulling fuel for about 3 min. Still full of air. Tried the bleeder valve. After about 1 min. or so fuel stopped coming through.

I'm thinking pump broke or clog? I checked for a clog at the intake (first 5' or so) and no clog there. I suppose it could be somewhere else. I also checked all the connections to make sure they were snug. Unlikely the connections went bad in the few days we haven't had fuel.

Anyone have experience with these? Can't justify another 150$ service fee yet.

Continuously running out of fuel sometimes draws contaminates from the tank and clogs up things.
When was the last time the nozzle and filter were changed?
Are you actually buying diesel fuel? And not home heating oil?
Is the tank above or below ground? Top draw or side?
Are you certain $300 in diesel has the fuel level high enough to reach the dip tube?

Thank you for the ideas:
Fuel filter changed about 1 month ago
Home heating oil, not diesel from the gas station
Tank above ground, top draw, and the fuel intake copper pipe is in the fuel, I pulled it out yesterday to look at it

Open the bleeder while the burner is running. Try to draw the fuel through.
