1/8 pt female port to -6an male, or how to get Defi sensor to Aeromotive fpr? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Anyone know where I can get such a rare pokemon?

I wanna thread my a Defi fuel pressure sensor into an Aeromotive fuel pressure regulator.

The Aeromotive fpr has 3x -6an ports, and a single 1/8 npt. I am currently using two of the -6an ports for my fuel setup, and the 1/8 npt has a normal gauge in it. The last remaining -6an is unused and has a plug.

I found this: Aeromotive - ORB-08 Port Plug with 1/8'' NPT Port
But it is npt, not pt.

My understanding is that although the pt will thread into the npt, it will leak because there is a 5 degree taper difference in the threads.

There exist 1/8 bsp female to 1/8 npt male adapter, and my research says that bsp and pt do work together to create a seal. But I don't really wanna use two adapters and have a messing bandaid setup.

I thought about tapping a 1/8 pt into the plug I have now, but I don't trust my fuel setup to this solution.

So Zilvia, please help me!

What is the point on having a gauge on the Fpr and one in the car? The 3 ports on the FPR won't work either. 2 are feeds and the bottom is the return to the tank. Your best bet would be buy an aftermarket rail with provisions for your send on it. Any greddy style should do it. And you get extra bling

I don't mean to call you a noob, but if you think hard enough you can find answers to all those questions.

Also, the pressure sensor will work as long as it's not the return side of the fpr.

Could this possibly work for you in line with the existing regulator feed?

hate to rain on your parade, but there's no one fitting that will get that done. Either step it to PT or BSP > NPT like the Honda kids do for their LSVTEC oil feed lines, or use a conventional -6 > .25 pipe > 8th inch npt.
