going on. I guess it's my Ghost messing with me again. first....when I put the new fuel line on my in tank pump I drained the tank first (drain plug in bottom of tank). when I got the hose changed I installed my new fuel regulator. went to check for leaks and when I turned the pump on it came up to 44 PSI (was 58-63), I was looking for 42-45 so that looked good. no leaks so I thought I would take it for a spin. when I reached for the door handle I realized I hadn't put any gas back in the tank. question is...how did it have 44 lbs. of pressure with no gas?
