131448, Obx fuel rail please help!
Posted by itsaslow95, Aug-27-10 09:04 AM
Hey guys I've been doing a lot of serching and can not find the size of the return threads on an obx fuel rail. This is basically all I need to finish my build, I'm going crazy!! I had a machine shop look at it and they said it was 3/8pt so I bought a 3/8 npt to -8am fitting and it dosent fit. Is anyone using this rail?! How are you returning it?
Thanks!

I don't run one, but 3/8NPT is the typical size...

Yeah, that's what I figured but it was too big.

If that didn't fit then take it to your local store and try them until you find one that does or go buy a thread pitch gauge.

Could be 1/4NPT, but that seems small to me.. *shrug*

Engine is in the car or I would have taken it there long ago.
I'm going to try 1/4" when I get home.
Maybe metric?
Thanks,
