Tom, Greg, few questions about the venturi:
Powerhwead- Manufacturer, diameter hole on cap, hole diameter (3/16, I assume) in powerhead inlet cover
Cap- where, and what is it (paint spray can cap?) size, etc., size hole for powerhead outlet into cap
Tube- how long, diameter, where you purchased it, scavenged, etc.
Sealed parts in place with silicone, I assume
CO2 input tube is neophrene, not hard plastic tube?
Got my order- great service, as always
