Step 1: Materials
2) Air Horn
3) Air fittings that fit the air-horn and a barb fitting to fit the hose
4) screw on valve stem
5)Hose clamps to attach the horn and tank to the bike.
Step 2: Screw off the top
Step 3: Add the valve stem
Be careful not to get the valve stem in the way of the trigger valve so it can be screwed back on.
Step 4: Add the hose fittings
To add the air fitting to the horn -In the bottom of the horn there is a threaded hole ready for a standard air hose fitting.
After you connect the fittings to the air-horn and the hose,connect them together. I had to use a step down fitting as well.
Step 5: Connect together
A regular bike hand pump works fine.
