Autometer boost gauge fitting

[DSM4LIFE-AWD]

Hey guys, I received my used boost gauge and I want to install it. I don't have the stock nylon hose with the ferrule so I want to know what is the size of the adapter on the back. I tought it was 1/8 NPT but it only screw 1-1/2 turn so I think it could be BSPT ? I don't have any fitting 1/8 bspt at my shop to test it so can anyone confirm me this so I can order the right adaptor to hose barb ?

Thanks guys !

Nearly every aftermarket gauge I have seen is 1/8 NPT. Only place I see BSPT is on the stock oil switch and pressure sender. Threads are all clean? You did say it was used...

I bought it used on Talk to replace my glowshift. The seller didn't send the ferrule so I need to find a way to use it.

Found my answer on Auto Meter and you where right on. Maybe my threads where dirty or maybe the 1/8 npt adaptor I tryed wasn't tap big enough and that why it was so tight ...

Thanks buddy !

No problem, glad to help!

Are there AdvanceAuto's in Canada? They have a kit made with 1/8" copper tubing, a bit more durable than your standard nylon lines: Copper Tubing Kit

Thanks but I wanted to know the adapter size so I can use a simple vaccum hose that is already use by my glowshift. Easier to connect on the throttle than the 1/8" hose ...
