A Wallas 30GB diesel heater was installed on my trawler 18 months ago. I have been more than satisfied with the unit until 3 days ago when it shut down about 10 minutes into the startup process. Inspection of the fuel line revealed just air in the line. After tightening all the fuel line fittings, the heater ran normally for 30” with the fuel line disconnected from the pickup tube in the port fuel tank and the end of the line placed into a gallon jug of diesel fuel. The metal fuel pickup tube was removed, inspected and reinstalled. The tube was not plugged and I could easily blow air through the tube. The in-line fuel filter (90 micron) had a slight amount of debris and no apparent damage. After reconnecting the pickup tube and the filter, the heater was powered up but no fuel filled the line. The fuel filter was removed and the heater again powered up with the same result; no fuel in the line.
The Wallas heater appears to be functioning properly but it is not receiving fuel to the burner. The port fuel tank is nearly full and the bottom of the pickup tube is 4” above the bottom of the 24” heigh tank. The duel Racor filter bowls have clear diesel fuel and no apparent water.
What am I missing here?
What is the next step?
Thanks
