Hi,

I just acquired a Polaris temp gauge add-on kit that I'm using on my 2002 Polaris XC 800. It came with a temp sending unit that has a 5/8" threaded fitting instead of the 3/8" fitting that came on the one I bought a few years back for another sled. I want to use the Grin-N-Rip aluminum housing like I did the last time because the damn plastic Poo one leaks, but theirs is sized for the 3/8" fitting (that size is also called "1/8 pipe thread").

Anyone know where I can find a temp sending unit that is 3/8" ?? I tried a dealer but they said they only have the 5/8" one.

Thanks,
Rob

Alternatively, if someone knows how to keep the stock Polaris add-on temp gauge kit from leaking at the plastic T fitting I'd appreciate hearing about it. I've already tried thread tape and pipe sealant goo without success.

Thanks,
Rob

Rob.. PM Sabercat700 "AKA Todd White" he has 1" T's that he supplies with a temp kit, I bought only a 1" T, that is what I am replacing my Polaris Plasitic POS with, althou the piece that Todd will send you will need to be machined/drilled and tapped for the Polaris sending unit, as the Polaris sending unit is bigger than the T hole.. mine new housing went to the machine shop for re-work today"

Hope this helps..

Thanks for the info. His fitting sounds just like the ones from Grin-N-Rip.

I just found out last night that my problem is mostly solved. The Polaris temp sending unit is actually a normal 1/8" NPT unit threaded into an adapter that turns it into a 3/8" NPT fitting. This 3/8" NPT fitting is the size of the Polaris plastic T. I was able to just unscrew the inner unit from the fitting and that works perfectly in the aluminum T from Grip-N-Rip. The only thing I have to overcome is that the sending unit is a bit too long so I need some washers or a suitable nut to space it away from the T enough.

So, if you want to use the T that you mentioned, as long as it has 1/8" NPT threads, you can just take the Polaris sending unit apart and you don't have to machine anything.

Thanks,
Rob
