I called back to ask them the same questions. It seems they meant for me to take the whole thing apart. So I did, and it was a pain in the butt.
Few lessons I learned...
1. Have to ultra careful with these screws. Even with the right star heads, I had trouble with one of the screws. I stripped the one screw, and I ended up having to tap it out. I asked the guy, and assumed, if it would be ok with just the three screws holding it down. He said yes it should.
2. Be careful with your teflon tape. I had a small piece that was caught inside of the solenoid. GOOD CALL MATT!!!
3. Make sure you know how it goes back together. Once I bore out the last screw, the thing popped off. In retrospect, I should've put the other screws in snug to hold it down.
Here are some pics...
You can see the teflon tape hanging inside the solenoid.
The guy told me once it's running properly I would hear the buzzing of the solenoid. I put it all together, and then plugged it in and out. I couldn't hear a thing. I'm thinking great now its broken. So I put my ear to it, and I did it again. I could hear the buzzing and feel the heat off the solenoid.
I will put the reg on a bottle Monday or so, and I will check to see if it is working properly.
Thanks for the help guys...
