Gauges are not always accurate, even when new.
The pressure the gauge "sees" may not be the same pressure the switch "sees". Sediment could be blocking one or both, but affecting each differently.
You can put a larger line to the switch, but you'll still have 1/4" inlet/outlet piping. I've even seen where a large piece of pipe, 2" diameter, was used to subdue the pressure waves caused by cyclying.
Good luck. My bet is that your gauge is sticking and not reading the pressure when it falls off through the footvalve or similar.
