Hello all,
I am installing a F 650 lower dash pannel right now and I am installing a water temp gauge but when I put the temp sender into the aux port on the sid of the water pump the fitting leaks no mater how hard I tighten it.
Any help is greatly appreciated,
Thanks
Nick

 

Is it leaking from around the threads or from the sending unit wire? Did you use thread sealant on the threads before installing it?

 

Yes I used thread sealant around the threads and its leaking from around the sending unit wire

 

mechanical or electric

if mechanical sounds like you didn't use the adapter

 

Its this one
AutoMeter Ultra Lite Coolant Temperature 120-240 Degrees 4333

 

that's a mechanical guage did you use the adapter

 

What adaptor are you referring to?

 

there should be an adapter fitting that the guage wire screws into and screws into water port ,that is what makes the seal


Ultra Lite Coolant Temperature 120-240 Degrees, 4333
Includes 12 ft. tubing.
Includes 1/2"" NPT adapter/fitting

 

Yes you should have a mounting nut(adapter) and a sealing nut the mounting nut goes into the port and the sealing nut screws into the mounting nut.

 

Here is what mine looks like. Am I missing somthing

 

There is an adapter that that screws into. Let me see I might have a picture of one. It is called an NPT fitting.

EDIT:



This is an Autometer 3/8" NPT fitting.

 

yes there is an adapter fitting that screws into water port and the piece you have pictured screws into,the bulb then seals in the adapter

 

But the one on that wire screws into the water pump so why do need the other one?

 

the other one is the other half of the seal

 

Because that one has a tapper to it that fits in the mounting nut and seals the connection. the mounting nut seals the port.
