Ok so I've modified the Unitank and not a gurgle!! Works lika dream!!!
Here's the parts of the Unitank
Top of the tank has plastic ring with openings to fit the chimney part
Botton of the tank shows where the chimney goes through
Now the chimney part seals that hole with the slots and the plan is to drill holes on the sides to let the juice through while making the chimney solid or none moveable
??
Base with the coil, spring and chimney
??
See the top and botton part of the tank and how the chimney seals the two.
At the top the chimney fits in the between the slots
When the top filler cap is taken off the chimneylifts and closes the part between the top and botton tanks and lets juice inot the coil if its not empty enough
Seals on the inside of the filler cap.
