I believe Ed and Kevin are using the "Century Camping" model 2118 with slight mods sold by Wal-Mart and others. ($18.00)(

It is modified as follows:
a. Remove the supplied Brass nozzle.
b. Remove the 1/4" long Galvanized pipe.
c. Drill and tap the supplied Brass nozzle for an 8-32 DuBro (or equal) Muffler pressure fitting.
d. Purchase a brass 1/4 pipe thread "Close Nipple".
e. re-assmble as follows: (use Teflon thread tape)
1. Thread the 1/4" MNPT Close nipple into the valve body.
2. Thread the 8-32 pressure fitting into the supplied Brass nozzle. (Use the supplied washer)
3. Thread the nozzle onto the close nipple.
**NOTE**
You could substitute a 1/4 MNPT x 1/8" barbed adapter fitting in place of modifing the supplied Brass nozzle.
Your done.
