Thank you for your question on the wire and circuit size for the sprinkler pump.

This will require a 120 volt 20 amp circuit using a wire size of 12/2 with ground, or what ever electrical code is in your area.

I will give you some installation information below in the image.

Thank you for your question on the well pump not holding its prime.

If this is a deep well pump it may be that the check valve is not holding the water in the pipe.

If it will pump water for awhile and then looses its prime it could be that you water table is to low and you are running out of water volume in the well. You may want to sound you well to check how much water you have in it.

You could try metering the water flow out of the pump with a valve to reduce the output to see if that will help.

This is also a pretty old pump and diffuser and wear ring and the impeller may be worn and is not holding volume.

If you have not replaced the impeller and the diffuser then I would at least do that if the pump has not been serviced for all these years.

I will give you the link to the part list for this model and I would suggest if you plan to rebuild the pump that you replace the key numbers on the parts list #5,#6,#7,#8, and #13 minimum.

Parts list for the well pump model number 390.262542 .

I hope this will help you with you well water pump.
