Q: When attached to air hose the unit is continuously "sucking air" through the system without pressing the thumb throttle. Is unit defective?

It could be, EB. The valve, when depressed, admits air from the hose off of a compressor through an eductor to draw the process, air fluids or other, by the Venturi effect. All of the air used for this will come through the vent diffuser opposite the hose connection. When the valve is released, the air flow from the compressor supply should be shut off killing the Venturi effect and eliminating the air coming out of the vent diffuser. Keep in mind that there is a trigger locking wire that can hold the trigger in the 'on position' so make sure that this is flipped towards the hose so that the trigger can release to its 'off' position. When your's is 'sucking air' without pressing the thumb throttle, is air coming out of the vent diffuser opposite the hose hose connection on the valve assembly? If no air is coming out from the vent diffuser with the trigger released, then you shouldn't be 'sucking air' and the unit would be in working order.

Q: How do i contact the company? there’s no website, phone, address or anything. how do i get replacement parts?

I need a replacement tube but I also haven't found a contact number, uggg

Q: Should i hear an air hiss when i pump? i do and i lose vacuum pretty quickly and have to pump repeatedly.

I think you lose vacuum when you hear the air his. It’s likely it’s coming from the adapter where you can connect an air pump to, but you don’t have to connect an air pump to it because it has a manual pump. So what I did was turn that stopcock perpendicular to shut that valve and then pump manually. If you meet some resistance stop pumping let the pump do the work, then resume pumping when the vacuum weakens. Too bad the package didn’t come with instructions. However this pump was really efficient and quick to use, not a drop of oil spilled.

I hear a hissing sound that seems to be air leaking back in. I closed the pneumatic valve but it still persists, Is there a fix?
