okay i bought a set of air horns off of an ambulance and i dont know where the 3 lines go that run off of the tank. when we put air in it no air will go in the one line and we cant get any air to come out of it. if you people out there could help me out asap id greatly appreciate it. THANK YOU

post pictures please and maybe someone can help ya

yea pics are a must!

U might need new airlineā€¦?

check the tank or airline for debris that might be clogging it.

ambulances typically use the HornBlasters 2 chime emergency horn but it should only take one line. maybe it had air brakes and used that tank for air too? idk i need to see pics
