I bought a Sunpro electric oil pressure guage that I would like to install in my 01 2.0 4cyl Tracker. The instructions suggest leaving the oil "idiot" light hooked. And getting a "T" fitting to install the guage with the oil light still operational. It says that I should go to the auto parts store to buy the metric "T" fitting, Is the Tracker sending unit metric or not,? I would assume it is but you never know until you get it out. Just trying to get everything ready so I can be like boom, boom and bang and its done, off I go. Thanks

 

I thought it would be pipe thread...was for my 84 fiero when I hooked my gauge up. good idea keeping the factory idiot light functional...you will never notice a low oil pressure condition without it.

 

The "metric" thread on the oil pressure switch conforms to the ISO standard which turns out to be the British Standard Pipe Taper (BSPT).
This is not actually a metric measurement but rather 28 threads per inch. Sealant or Teflon tape must be used on tapered threads to prevent leakage.

 

That exactly what I was needing haha, Thanks.

 

Here's a quote from a Sunpro review on amazon:

"Also make sure you have the correct adaptor. The sending unit is 1/8" NPT, but japanese anything is pretty much all 1/8" BSPT. My honda, toyotas and yanmars are all 1/8" BSPT. The correct adaptors can be tricky to find."


BSPT is close to but not compatible with NPT (National Pipe Taper). This adapter will allow you to connect the Sunpro sending unit to the Tracker engine block.
You will need handful of extra BSPT fittings to "tee" 'in the Tracker's original pressure switch.
