I have an Autometer FP gauge on my truck and its rattling bad now. Its under warranty so I am going to replace it (for a 2nd time) this time I'd like to install a needle valve in my setup. What do I need for a needle valve install? All my lines are 1/8 npt. I'd like to install something so I don't destory another gauge again. Thanks!

just go to hardware store and buy a 1/8"npt brass nedle valve i like snubbers better but the needle valve is only about $2.50

 

Thank you!

 

I got the needle valve on and it took away my noise in the gauge. I got it and a coupling at Ace hardware. My local home depot and menards didn't have anything. Thanks again!
