Pressure problems

Ran out of water had load delivered have 20 ft of water above foot valve. Put new foot vale on filled line with water as well as line going into house.\
Shallow well jet pump. When I prime pump after several tries get up to 25lbs can no get any higher

Plugged ejector on jet will give you that symptom.

Some pumps will destroy themselves if they run dry...don't know if the type you have is one of those...you may need a new pump if it ran dry for long.
