Fuel bowl heater question.

I just found the element on my fuel bowl heater has pulled loose from one of the pads. I soldered it back on. Does anyone know if this will short it out or will the resistance of the element keep it from shorting? I measured from the element to the disc it is mounted on and I get 1.7 ohms and from the connector to the element is continuity and across the disc reads continuity. Is 1.7 ohms enough resistance to prevent shorting? If anyone can help me or measure the resistance of a known good one and let me know what the resistance is from the element to the disc it is mounted on, that would be a huge help. Also, does the disc sit directly on the filter housing or is there supposed to be a gasket or o-ring under the disc to isolate it from the housing? I think it has to contact the housing to complete the circuit but I need to find out about this before I put it back in and blow a fuse or something. I'm at a stand still until I find out.

Bump... I think! Does anyone know about this? Is it fuse #22 or #30 that will blow if the heater shorts and can anything else be damaged?

12 volts divided by 1.7 ohms equals 7 amps, should be okay

Just unhook the plug going to the heater. It won't effect anything. The pads mount directly to the fuel bowl. I used 5 min. epoxy on one years ago, before I knew you could just leave 'em unplugged. You are right about fuse 22. It also supplies power to the PCM, if remember correctly.

Thank You! That was another thing I was wondering, whether it was 12 volt to the heater or not. I'm going to put it back together in the am and hope for the best. Do you know which fuse protects that circuit? Thanks again.
