Fuel Rail Pressure Sensor on Billet Rails...... need O-ring or washer?

[Bonedizzle]

I am installing some Billet -8 rails on a 2020 GT. I purchased Radium 14-0359 M10x1.0 Female to 1/8NPT Male.

I know I need PTFE paste on the 1/8 NPT portion of the adapter, but is there supposed to be something to seal the sensor to the adapter?

There was nothing in the packaging except for the adapter. I did not see any sealing washer or O-ring when I removed the sensor from the stock rails, and there was nothing left behind in the port on the stock rails.

A picture of a replacement sensor does not show a sealing washer or O-ring.

There is a video from VMP Performance on installing aftermarket rails, and they use a sealing copper washer, but they are using a different adapter.

I know I can contact Radium, but I figured someone could chime in faster here.

I used the same rails and I was almost positivie there was an o-ring. I definitely didn't use a copper sealing washer and mine does not leak.

It does appear that there should be an O-ring to fill that void. I have a question out to Radium tech support. I have an assortment of O-rings that will hopefully work if I need to use one.

Radium informed me that the sensor is flared, and no sealing O-ring or washer is needed.
