How do you check if the fuel heater is operating? What temp should it heat the fuel?

 

The best way would be to find someone with a dc clampmeter to check the ampload, otherwise you can check the ohm reading by unplugging the wire connector and making sure that you get a resistance reading, then check for voltage on the wiring harness supplying power to it. I think I read somewhere that it has to below 40 deg. for the fuel heater to turn on, but someone that knows a little more about these can correct me.

 

I deleted my initial message. I was thinking grid heater.....

 

Fuel heater should operate when the fuel is between 45±8, and 75±8 (IIRC)..

Other than resistance or ammeter I am not sure. Maybe an IR gun on the inlet and outlet of the fuel canister when the fuel is known to be below 45*F

 

How do you know all this stuff??? Must have a mind like a steel trap, and a perfect memory!! Glad you're on this forum!!!! THANKS!!!
