Where are you hooking the sender or gauge ?? are you drill and taping the banjo fitting or is there a place to mount it ???

 

At the fitting on big pump that has a plastic cap on. There is a valve similar to a tire valve. You thread out the valve and install an adapter on the threads that the plastic cap threads on to. You need a JIC tapered fitting.

 

Where might one find this adapter fitting and what is a jic taperd fitting???
Thanks Bud

 

As stated already, all you need to do is get in contact with someone who bought a Campaign 504 pump, they all come with the sensor/harness. All you need to do is wire it up to a light.
Cheapest (free) way to go about it.

The SMARTEST way to go about it would be to forget the dummy light and get an analog gauge.

Good Luck.

 

I am sure some one can tell me where I can buy a fitting that goes on the fitting with the plastic cap
Thanks Bud

 

I would assume an HVAC supply house, it is a standard schrader fitting.
