Stop in for a cup of coffee

Whats up when you let a car sit? Worked on the pop a bit yesterday. Cleaned up that side of the shop to get a sun cabinet out. What the hell let me hook it up to the wall scope. Ok do it set the engine up notice fuel pressure dropped from 6 to 2. OK fuel gauge is now not working maybe out of gas. Pour in a few gallons no change. Freaking fuel line looks like it got chewed through from the tank to the pump. I really am going over this whole car, brakes are like a rock with no power, were great before, every thing new, even the rear disk set up. etc etc!:BangHead::BangHead::BangHead:
