Does anybody know what type of threading (flat, tapered etc.) is used on the Ultimate Racing fuel pressure adaptor? How about the what type of threading is used by Defi for their pressure sensors on the BR gauges?

I would call the vendor but do to the time/holiday weekend I do not think they would answer and its kind of pertinent this moment.

Thanks.

 

I have a SW fuel pressure gauge hooked up to the UR adaptor. I think it is 1/4 NPT.
