    Bought a new tank today. $189.

    I'm kind of wishing I would have had the shop install it. I know once I start messing with these air controls, its gonna get hairy!!! They look stubborn as you can see in these pics. :( rusty.

    I guess I'll attempt to change it this weekend. I bought a couple extra couplers just incase.

    A little heat and some persuasion and those couplers will come out with ease. They're brass so even if they do break you'll have to chisel the rest out chunk by chunk.

    I did this this year. Tank cost me right at $100 but mine was a rare size and took awhile to find. Couldn't find one new, had to find old stock. The plant that makes them didn't have any and weren't going to make any soon......covid times.

    When I know I got a job like this to do I like to spray all the threads with penetrating oil a few days or a week before I tackle the job.

    Best to use liquid Teflon or the regular "tape" kind on the new couplers? Or old couplers if the cooperate.

    I've only recently started using the liquid brush on type and I'm not really sold on it. It's convenient and easier to apply but it attracts dirt and debris on the brush no matter how hard I try to keep it clean. Of course, that trash inevitably makes it's way into the container too. Frankly, it's plain messy.

    I'm also paranoid it will get sucked into the system since it's a liquid so I let set up a little while before screwing the fittings in. The tape has none of these issues and it's cheaper but it has it's issues too. 12 in one hand and a dozen in the other I guess.

    I would definitely use the new couplers no matter what with some sort of thread sealer on them if I was doing the job.

    Lines all have quick couplers. That’ll make things easier.

    It's supposed to, at least. I love quick couplers and they certainly make maintenance on trucks a lot easier but they don't often come apart as easy as they go together. With the mileage on my truck and trailer just about every one I fool with is a ##### to get apart and often it's toast when I finally get it apart.

    I'd presoak everything a couple times before the job, even the quick couplers.
