joes mack Posted January 5, 2012 Share Posted January 5, 2012 the fire dept that im on has a L8000 ford tanker that we are starting to have problems out of the air system on. the air leaks off in about 4 hrs but we cant find the leak and it takes about about 5-6 min to build up which is a long time if we have a fire im thinking it might be the regulatior what do you think. ive made fittings to put air hose to the tank but it will only air up one side of the system (primary) should this air up both sides if so do any of you know where the check valve should be or if it might be stuck or pluged up. thanks in advance joe Quote Link to comment Share on other sites More sharing options...
