Resolved Evo 9 OFH fittings?

[PrimerPLus]

I have my Evo 9 OFH installed.
What fittings do I need to fit in these spots so I can run my dummy light switch and my AEM oil pressure sensor.

Believe it or not those ports will be BSPT (British Standard Pipe Taper). There are no NPT ports on a Mitsu part. The small port will be 1/8 BSPT and the bigger one will be 3/8 BSPT. However, having said all this, NPT will work because they're so close. I just thought I should point out for anyone who refers to this thread in the future, what the actual ports are.

One of them will screw right in to the evo ix no problem. The other one we just used a reducer from the larger port on the evo OFH down to the size of the sensor. I can't remember the sizes but we found a decent reducer at ace hardware in the plumbing section so it must be common. We just took a bolt that threaded in to the OFH and the sensor with us so we knew what size.

I will head to ace thanks

Did you find one that threaded in ok?

No they did not have a fitting at lowes or home depot. I will have to order online

This is what I will be ordering to run my AEM oil pressure gauge, stock oil pressure gauge, and Dummy Light.

Seems a lot more complicated than what we did but if it works for you, great! Lol

Good luck. Hope you get it up and running soon.

You might be right haha.
But I wanted to run 3 gauges and this will do the trick.
That evo fitting was impossible to find from 3/8 bsp to 1/8 npt but found that one and was relieved.
