Anyone know how to remove this seat air line thingy?

Depending on where its located, yes this connector may have full psi at all times. That raise/lower button may be upstream from it so draining all the air would make it easier.

 

Hahahha 120psi seat that would be a fun ride when u pull the lever to air ur seat up lol

 

You do realize it takes a few minutes to air up a tire because the size of the hole (valve stem) the air has to travel through right. And it takes longer if the valve stem is put in first making hole even smaller. And another thing, if your tank pressure is 120 it will be hard to get 120 at the end of the delivery line with out some considerable time. If you air governor is set to 120 and you air up a trailer tire through glad hand and a 50 foot air hose your not going to get 120 in the tire.
In other words, if you hold the button on the seat long enough you will put about 110-115 in the seat but it will take a few minutes. To think that you would get instant 120 through a 1/8 or 1/4 line is ridiculous.

 

Napa truck has the pliers for these connectors. If you have a welder, you can fab up something with a paid of channel locks.

 

Exactly. I'm sure anyone who has been out here for awhile at one point has had a supply line to the seat crack or break and it just continuously blows air on the old ragged out company back up truck no one wants to drive.

 

5 dollar fitting usually start leaking after disconnected several times I carry spares js

 

This shows it and its easy as well you get the point.

 

Buy a new one and cut the old one off

 

I’m having a hard time finding a 4 way quick connect for Truck HVAC lines. Very small air lines. Dealer no help.
