Leaking Air Line into Air Tank

Look closer. Its a flare fit quick connect. There is a small ring that you push towards the tank then you can pull the line out. This ring has like a little jaw. Picture a Chinese finger trap. That fitting works the same way. Once the line is off, cut the end and make sure end is flat. You want it even, then push it back in. it should take care of your leak.

 

i like the way you explained that (chinese finger trap) i hate those fittings everytime i have one leaking i replace with a feral and nut style.

 

Those forever failing fittings are used to speed truck assembly time on the line, and the end user gets to pay the high cost for them. I don't use them unless there's a clearance problem otherwise.

 

Just as bender and superhauler said:
Get rid of those pushlock fittings. They are quick and easy but are a leak waiting to happen.

 

the fitting should just be threaded in the tank. unless it's something brand new they have came out with.

 

You pop the snap rings and replace with same fitting. That's the new tank design by Hendrickson used on the 2007 to 2010 internationals. 2011 they changed to the Meritor tanks with thread fittings because the Hendrickson design has too many problems.

 

I have a 2006 and having the same problems. It's not the line leaking, but looks to be the actual fitting itself. Got the snap rings out, but how do I get the fittings out? Just pull out or are they threaded. Just didn't want to tear anything up and end up costing more.
