GEEEZ- Just pay the $39.00- the hanson UAT (of which you borrowed the pic) is a BVM uat with a couple of changes/improvements. (I dont consider the Festo fitting for the suction line an improvement as Festos leak under suction BTW). What are you going to save $5-10 bucks doing it yourself-and spend hours to search out all the parts and then assemble it?? And BTW the center bag support festo attachment is a customed machined part by both Hanson and BVM. Have fun. Scott
Not to kick this person's efforts around, but I agree about the fitting choice. A captured barb fitting is FAR more preferable anywhere on the suction side of the pump. If you must use quick connect fittings, I wouldn't use them anywhere but upstream of the UAT...
The other thing about the tank that I find a lite unnecessary is the extra filter. The sack itself is an filter element... Adding a filter inside (which looks particularly fine) will result in a rise in restriction as it clogs up, sometimes occurring quite rapidly. I've had this happen with a membrane clunk. The far preferable route is to lessen the restriction upstream of the pump and install something like a Hanger-9 filter downstream of the pump. Its easy to service, it'll avoid cavitation, and most importantly it captures particles generated by the gear head. Also, I'd bet nothing finer than a 50 micron filter is really necessary, since the smallest orifice in most turbines is probably an the order of 200 microns (rough guess)...
That hard part of making a UAT is getting / making the tank/fill port fittings. Perhaps the seller should sell those if he's really interested in providing hardware to the RCU jet community. I'd consider buying a set or two depending on their design...
