76 k100 won't shut off

I have one last question in this thread I purchased the 5/32 air line upgrade kit for my 9513 and air is leaking from quick connect fitting at shifter are the new type of floppy nylon rubber hoses not good to use and should get the hard air suspension hose type to use? does anyone else use the new rubber type and no issues? thanks

 

no power when key is off to shutoff and truck now again shuts off immediately when I turn key off

 

it is 12v solenoid. I don't have any electrical issues it is a 12v/24 volt system. The truck has GL at end of vin and original owner put the 290 in it with rto9513 trans I did a 2016 w900 cutoff in it w 3.36 gears.

 

had her for 24 years and last 10 years sat in storage cause I had too many memories with my father and was hard to climb back in after his passing

 

61 vert is my next project
