KP Dual Needle Gauge Question...

hey guys, sorry to waste a new post for this, but i just got 2 dual needle KP gauges on the back of each gague there are 2 treaded male posts (3/8???) with a little 1/8 female hole... i went to the store today and 1/8 air line fits in the hole perfectly... my question is... do you guys just run 1/8" line for your gagues and cram it in the female hole on those posts... or should i get a PTC fitting that fits the threaded post and my line...thanks guys...

you get a 1/8 fpt/1/8" tube fitting

or you could get the male version of this and use a coupler.

innovativeairsuspension.com or suicidedoors.com has them, i think gravity works sells them too.

thats exactly what i was gona do, however the location of the ports on the back of the gagues doest leave much room for a fitting to be screwed on...? was i right about the posts being 3/8"?

the fittings on the back of the gage are eityher 1/4in or 1/8in havent looked at the back of my gages since i installed them but yah the picture above my post is the fitting yr lookin for..

there 1/4 on the back of the guage

i have PTC fittings on my guage with 1/4 copper, but 1/8 line is just as good.

KP gauges have 1/8" Male fittings, but you can get the 1/8" female.. to 1/8" OR 1/4" line (personal preference really) I use 1/8" since its cheaper and easier to run around behind the dash and all..

Ricky is right. Its 1/8npt male on the back of gauges.
