This set is totally assembled by the Big Dog. 
 
Configuration note: Regs come standard with long hose primary and bungee necklace secondary...but are also available in "tradiitonal" configuration: short primary hose, and yellow backup hose. Please indicate "traditional" in the options section if you would rather this configuration. 

High pressure hose for SPG (24") can be either nylon braided or traditional rubber. Please specify. Rubber is tried and true. Some makes of nylon in HP have suffered failure in past years, although I have not read of such failures in recent years. The choice is yours. Nylon hoses are significantly lighter and more flexible.
