'''Do you have a air dryer? If so get under the truck and listen to the exhaust port for leakage. You might have a bad purge valve. I would also suggest that you take a a 3 gallon one you can buy at Lowe's and fill it with water and dish washing liquid and spray all your air lines down and look for bubbles. Strato-flex air lines with the fabric cover are real bad about silencing air leaks and can only be found by spraying soapy water on them and looking for bubbles......... '''''italic text''
