Airbag fill ports?

finally got to putting the trailer on the ball after installing this kit. went from more than 3" drop rear, 2" raise front with the factory system to about 1" drop rear no raise on the front with the bags at 50 psi.

i need to find a different air gauge, all three of mine start at 20 psi, even the one for my pedal bike. Not sure how to find the low 5-15 psi recommended "unloaded" pressure for the bags.

Most digital air pressure gauges go very low. I've three different ones and they all go below 10 PSI.

Low pressure gauges are available for ATV and SxS tires.

Mine are where the top license plate holes are.

Maybe I misunderstood your earlier post

As said above ,no need to drill holes, they are already there in the license plate .Remove the license plate bolts insert the valve ,and put a nut on it, and cover with a plastic valve cap, couldn't be easier ,and acceable .

Its been awhile since I did them, if they had just the screw thru that plastic, then yes I would of drilled them out so the air valve would have went thru it, and the license plate . As said pretty sure the air line kits comes with a couple nuts for the valves to be attached. I know they are thin enough to allow a valve cap. I ran a fill line to both airbags. I did not tee them.

I did this for years before I built onboard air... I ran the bag air line into the cab, under the driver seat, through one of the plugged holes in the floor board and I used a cheapo $14 compressor that plugged into the cig lighter to air the bags while on the road. Craig

Screws not bolts in the top, no holes at all in the plastic for the bottom plate holes. The screws up top are right into the plastic, they are regular sheet metal screws. No nut or backing plate.
