Air horns to replace stock ones

[MyothersanM1]

Get yourself one of these, a Nathan P3, or similar.


And activated through one of these, a Graham-White metering valve. Almost turns the horn into a musical instrument The whole set up is plumbed with 1/2" DOT nylon air brake tubing and push-to-connect fittings. It's connected to the dry tank on my M818 through an 8.5 gal auxiliary tank mounted behind the cab. Absolutely no air volume issues. Air gauge needle hardly even budges and I can hold it wide open.

Any links to a good price on the Nathan horns?

I replaced my stock horns (actually, just re-plumbed them) into a single fire engine horn. No more wimpy USMIL horn. It now has a horn to match the truck, LOUD AS ****.

How do you adjust your air pressure up to 135psi?
