If you have lots of height drop from the last tap to your shed:
Install a small tank with a float controlled drain about 35 feet above your storage tank.
Connect a (dry) vacuum line to the top of the tank
Connect the main line near the top of the tank, not near the vacuum line
Run a main line size pipe from the drain to the storage tank at the shed
Turn the end of this line upward for several inches or a foot.

This is known as a barometric leg. It serves as a releaser.
