Glad Hand Tire Inflation Unit For The Truck?

I'd also recommend checking the air dryer when you're done, too. If it's got a manual drain valve drain it just like you do daily when you park it.

 

Years ago I bought the 50 foot soft rubber hose it was slow as heck airing up tires until another driver saw me using it one day his advice saved me a lot of time once I applied it . He suggested changing the chuck or drilling out the restriction hole it had inside. I swapped the chuck and it was 10 times faster. I don’t know if all hoses are the same but if you remove the chuck and look inside it should be wide the full length it there a block off with a small hole replace it and you get full pressure now.
