My pop off valve is rated at 175 so for now I will run the 150 psi pressure switch. Then when I get the money I will get a 220 pop off valve, put on the 200 psi pressure switch and a regulator.

Also, can I get a link to a good regulator for between the tank and the horns. And should that regulator come before or after the valve?

I am pretty sure it needs to come before the valve…I would think. Lol

I think so too. If not the valve would build back pressure between it and the regulator.

Just got off the phone with HB, got them sending me a 235psi pop off valve and 2 more ptc fittings, also a reducer to hook up my digital gauge.
Well I will be picking up 5/8" ptc and line tomorrow, and ordering a regulator too! Might as well do it big with the K5s!
Haha busy fellow! You won’t be disappointed
what regulator? i am on the hunt for one also. lol
McMaster Carr 225cfm 1/2" regulator with gauge - 4959K303
Bracket for regulator - 4910K98
Thanks bro!
Looks great man! May be a pain at times while you hook it up, but a big sigh of relief and a huge smile once you finish and get to honk it for the first time!!
I called HB because they sent me the 150 psi pressure switch with one built in relay and then the 200 psi switch and 2 relay blocks. I told them I did not understand why I was sent the 150 psi switch and why they sent the 20psi with 2 block relays when they make a 200psi switch with 2 built in relays. I talked with nick, he took care of it and I have a 200psi switch with 2 built in relays on the way!
I also asked about why they dont sell 5/8" ptc and he said I wouldnt need it so I will save that 80 bucks and see how the horns sound with the 1/2" and go from there. thanks for everyones helpe. specially ear2ear!
No problem. It’ll still be ridiculous!
Well my guage came in from hb, the air-zenith, it is a BA looking guage. Can’t wait to get it the truck!
My regulator should be here tomorrow along with my connectors that HB left out and my 200psi pressure switch with 2 built in regulators. So by monday/ tuesday everything should be in!

what are yall doing for security, where someone cant just go under my truck and unbolt my horns?
I bought SS security bolts from my local Fastenal. Can’t remember if I posted pics in my install thread or not. Most people don’t carry a security bit with them 
Here you go:
Machine Security Screws
&
Security Bits
or
Security Drivers
You can order them online or go into the store to order.
I’m sure you can find them other places online too i.e. McMaster-Carr.
Thanks bro!
