Default LT 1050 Fuel Pump

Sounds to me like you should remove the line from the tank to the pump and check it. Might be blockage somewhere in the line

Am I correct in assuming that you are squeezing the pulse line from the crankcase/ valve cover? Or one of the other two?

Check that the gas cap is venting properly.

All vacuum-operated/pulse-type fuel pumps operate off of the air pressure/vacuum inside an engine's crankcase. The moving piston(s) inside the crankcase create a pulsating effect of air ç back and forth to activate the pump's diaphragm. And all vacuum-operated/pulse-type fuel pumps come with three fittings - one that connects to the engine crankcase, and an IN and OUT fuel hose fittings. It should read on the body of the pump which each fitting connects. But if it doesn't, then the fitting coming from the center of the pump connects to the crankcase port.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
