I just did the lp pumps, filters, and hp pump screen cleaning. I tried to take pics but daughter had camera locked in car

I did not have a manual. I removed the entire VST tank after draining and held the flange in vise. The screws are loctited in and the heads will strip easily. You will either want an impact screwdriver or hammer the hand screwdriver so as to shock the loctite. You obviously can't put heat on it, it's been full of gas/oil. The o-ring is all that needs replacing ($40) unless you opt to replace the screen. I cleaned mine with spray cleaner and light compressed air. It's like the permenant coffe filter material and kind of 1/4 turns off. The lp pumps and filter are straightfoward.
