INSTALLING BRAIDED STAINLESS STEEL AIR LINES

KEEP THE AIR LINE AWAY FROM THE FUEL LINE, BRAKE LINES AND ELECTRICAL 
WIRES. 

1.  Use zip ties to secure 

the air line to fixed points 
along the chassis every 
6” to 8” (150-200mm). 
Leave at least 2” (50mm) 
of slack to allow for any 
movement that might pull 
on the air line.

2.  Tighten the air line hex 

nut finger tight, then use  
2 wrenches to turn  
1 additional flat  (1/6  
of one full turn). 

Do  

not overtighten  
(Figs. E.4 or E.5). The 
easiest way to tighten the 
fitting is off the vehicle. 
Install the Schrader valve 
in the chosen location.

3.  Coil and secure any 

excess air line in an 
area where it will not be 
susceptible to damage. 
The braided stainless 
steel air line cannot be trimmed.
