Siphon tube needs a 2" long 1/4" NPT extension when upgrading from older valve
Nice piece. The only drawback is the siphon tube connection is deep in the valve. If you are replacing an older valve without any ports on it for gauges/pressure switches you will need a 2" long 1/4" NPT extension to get the siphon tube installed and sticking out the right distance to reach the bottom of the bottle. I also had to purchase a 1" threaded female to -4AN male adapter for the valve to connect to my -4AN line to the engine.
