2166 Fuel Line Replacement

I finally decided that I would replace the fuel line on my 22 yr old cub cadet.
Someone posted a video on YouTube showing their experience (https://www.youtube.com/watch?v=GF9yPqmz1ng).

The process is pretty straightforward and took me about 2 hrs.

The main takeaway is that the fuel hose was in ok condition everywhere except where it connects to the tank. The tank hose connection is right above the hydro oil pump which gets hot. Over time the hose degraded to 'crunchy' at the tank connection.

I couldn't see any evidence of fuel leaking, but leaking fuel on a hot oil pump sounds like a bad combination. At the very least, this section of 'crunchy' hose probably let air get sucked in and contributed to my ongoing 'slow to start when sitting for a long time' issue.

So for all those 20+ yr old 2000 series cub cadets with original fuel hoses - think about changing them out!

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.
