Differentiating Between Bennett Hydraulic Power Units 

Good video however would be much better if the background audio was turned way down or better yet turned off. He has good information but hard to listen to with the very annoying background noise (music ?). Thank you. Note: I own your product.

What is the difference in plumbing for the dual acting pumps? If it is for operating two separate items, why are there only 2 hoes connections? How would you operate two trim tabs and a hatch with only two hoses? What is the wiring for these pumps? why not show? What does "special wiring for OEM" mean? I install/service these units daily and have only seen one dual acting pump. It has a blue and black wire, meaning it only spins one way. How do two tabs operate with a pump that has 4 valves and only spins one way?

Great stuff old boy but could do without the music
