the 9 dollar auto drain kit does not even work out of the box,,, no big surprise there,, but here is how i re-designed the junk so it works.
first take it apart pull the 1in flapper out and throw it away. doing this fixes the unit....
next you will need Grainger Item # 2VKR6 for $17.37
this is the correct tubing,, as the tubing they give you will blow out at 100psi and or melt.
after that,,, take a tiny c clamp and clamp the tube down to limit the air flow,,, and it works like a charm.
