air guages

ok ive been running without guages for too long....

what fitting do i need to connect a 1/8" line to the back of a viair or kp dual needle guage. or what kind of connecter is on the back as i have never seen the back of one....

thanks,

so do i need the 1/8" or 1/4" which one is on the back of the guages?

both of those are the same fitting on the gauge side, the difference is on the air line side, wether you are running 1/8 or 1/4 line. If youve never ran air line to gauges before I'd recommend 1/8 inch.

my bad thanks man....
