Anyone know how to remove this seat air line thingy?

Now your making it even more complicated, all this when all you gotta do is pull it apart and put it back together. Simple

 

Very true well i guess i could only dream that it would be a fun ride since u just ruined all my hopes and dreams lol

 

I'm with you on the volvo ejection seat. LMAO

 

They can be a bit stubborn the first time you disconnect them.

 

I bought a 4-way 1/8" line connector from freightliner dealer It is used to power the vent selector switch.
99 fld120. It was less than $5.00

Good luck

 

Thanks I’ll try a different dealer

 

Cross Union Fitting quick Release Connector, 4 way air fitting
This will tell them what you need. And I bougth a dozen inline fittings and 2 45's along with one 4 way on ebay last year. I think shipping and all was less then $8.
Heres one off Ebay for less then $2. Tube 1/4 Pneumatic Cross Union Connector Quick Fittings Push In OD 4mm | eBay Will take 2 weeks to get here. Or theres also this link for 10 at $7+ 10x Tube OD 6mm 1/4 Pneumatic Cross Union Connector Quick Fittings Push In | eBay
That's for 1/4" if yours is the 1/8" I think there on there also.

I used a pair of T's and a short piece of pipe one time. Worked in the dash of a FLD.

 

I was gonna just use 2 Ts, but thanks I’d rather use 4 way

 

Morning drivers. I know its a year old thread. But no since in starting a new one.
How do I size the air hose that I need.
This 2016 cascadias has the air line quick connect. I wasn't to put in a sprayer gun. But don't want to go to the store twice.
Also I'm assuming it won't, but will it affect it in any way being on the driver side. The passenger side is not air ride?

 

It's pretty simple. The kit includes everything you need.
