Hello,
I have a 182B that is having some issues with the Javelin / O&N / Griggs 18 gallon aux tank on the floor of the baggage compartment.
The pump control switch is 3 position - off, on, and a spring loaded "start" momentary action position that is supposed to be held for 10 seconds to start the pump. When released, the switch springs back to the on position and the pump should continue to run.
Problem is, the pump only runs when held in the start position. When released, the pump on light extinguishes and the pump shuts down. It doesn't matter how long or how many times you hold it in start. I can, however, hear the pump running when the switch is held in the start position (when testing it without the engine running).
Secondly, the fuel tank drain/sump sometimes stops draining even though fuel is in the tank. It is very strange and just depends on the day...sometimes it will drain a few cups then stop, sometimes it will work normally, other days it won't drain anything.
Thirdly, the tank only seems to hold about 16 gallons maximum (maybe this is normal?).
Is there anything I can do to troubleshoot this or is time to break out another thousand for an A&P?
