Re: First pressure tank….

When you have the top of the tank off, unscrew the gland nut on the top of the fuel pick up tube. Shake the tube to see if you can hear the check valve ball rattle in the bottom of the tube. It may be stuck. The check valve lets the fuel go up the tube but not down back to the tank. If it is stuck, squirt some carburetor cleaner in the tube, let is soak for a minute or two then shake the tube again. Repeat until the valve ball is loose. You can also check by sucking on the top of the tube to see if the valve is moving off of its seat. Try blowing through the tube, if you can’t blow any air through the tube the valve is working.
