OK not excatly sure what you don't understand about Isolate and Eliminate - if you take each item mentioned and disconeect that item and it runs - then that is it. If you disconnect the filter and it runs fine I don't give a rats ass what the guy that sold you the motor says thats the problem. I also don't intend for you to run around all day without the cap - come on - just crack it or something to let some air in it, thats venting the system. Thats why I told you to do each one separate - so you will know which item it is. If you crack the cap, disconnect the filter and bypass the bulb and it runs fine, which one is it - you have no clue. So disconnect the filter again if it ran fine without it, try it and if runs fine something is wrong in the filter, pretty simple. You have to remember - mariana guys are not as smart as they think they are, and your not as dumb as you think you are.
I used to be a marina guy but its too hot out there, just do what I tell you you'll find it
