So if you're wiring up a Defi pressure gauge, you'll need a tee adapter.

BSPT Male = into engine
BSPT Female = oem pressure switch
BSPT Female = Defi gauge sending unit

Additionally... this part is NOT AVAILABLE in any country by any manufacturer.

However, there is a BSPT x BSPT x NPT adapter available.

THEREFORE, we must use:
  • BSPT Male = into engine
  • BSPT Female = oem pressure switch
  • NPT Female = Defi gauge sending unit with an separate adapter from the BSPT Defi sending unit to the NPT threads of the adapter.

So I am going to make a custom manifold for this as my current setup of adapters is touching the sway bar.... What I am thinking is a block of aluminum with the following for ports, in a remote spot :

1/8" BPST female port, will have a flexible braided line from manifold to engine
1/8" BPST female port, for the OEM pressure sensor
1/8" BPST female port, for the Defi racer pressure sensor

Does this sound like the correct thread sizes? Just want to be sure before I buy a tap and drill holes.

Thank you
