Ok, now I c it. Do I remove that one on the hose end? Also are you sure it’s 3/8npt?
I was thinking it would be 1/2 to tank and 1/4 to the hose.
You need to remove the hose from the compressor and make sure that air is not leaking out via soap bubble. I’m not sure what the npt is on that compressor. Mine is 3/8", but your may not be. Check it first to see if that is what is leaking. Double check ALL of your fittings and hose connections while you got the soapy water bottle out. 
How often do you guys drain your air tanks? Seems like mine has water each time I drain it (every day).
I do once a week if I use them a lot. If I don’t use them a lot, then about once a month. The more your compressor runs, the more moisture your tank will have.
here is my k5hla and my k3l both on my truck
this horn is now a k5lr24
Nice job ! good pics…
thats awesome man!! got a video of them? i wanna hear how loud they are
Looks awesome. That K3 fits like a glove.
So how did you reverse the 2 bells on the K5? It looks like they would hit the tank.
Any pics with both sets in view?
They look great.
Yeah the k3 I had to build a tripod for to be able to put it there (upside-down). It looks like it has room to the top but it won’t go up because of my transfercase. But it’s a real tight fit for sure. The yellow horn was my k5hl but I put the bells on a low manifold and reversed 2, 4. That horn is not on my truck anymore. The john Deere is a k5hla. I’m working on a above the cab mount for my other horns for videos and I will post some pictures and videos of my other horns as well. Just been crammed with work and haven’t had much time.
That’s awesome! Great job on your install.
BUT, I recommend relocating the air filters on the air compressors to a high and dry location. They do have a 1 year warranty, but it will be void if the air compressors take in any moisture or debris.
Keep Honkin!
Yeah I relocated them with a hose kit they are behind the fenderwell now like you told me to put them.
Can someone go into detail on how to take the horns apart to paint them or show me a thread on them! send me a pm thanks!

I have a K3L and a p3 on a p5 manifold.
