Fresh Water Fill

Why does fresh water continue to overflow 8 gallons or more even after city water is shut off. Pressure fill only, no gravity fill available on a 3013 Sunny Brook Raven 3300CK fifth w. The 56 gal tank only takes little over 40 gal. before
overflowing. Air vent was worked on.

The tank may have been slightly pressurized from over filling.

If the vent hose outlet is lower than the top of the tank it will siphon down to that point.

If you are saying your water back-flows out of your tank after turning spigot off, you might try filling more slowly. If you have access to your vent, you should be able to hear and feel the air rushing out as you fill. It could be your vent is too small.
I don't understand why a 56 gal. tank would only hold 40 gals...
