This is causing your Fuel Supply Pump to "lose its prime".

The Fuel Hoses can be replaced for $1.20-$1.50 per foot from any Auto Parts store as their Regular Fuel Hose is also rated for Diesel Fuel. The size is 5/16 of an inch inside diameter.

If you still have the Old Style shiny Aluminum bodied Hand Primer on the Fuel Supply Pump (mounted on the side of the Fuel Injection Pump) that is often the cause of air leaks. Get only one made by Bosch as some of our members have reported not so good quality control on some of the copies. The Bosch one is between $20 and $30 on the internet.

A less likely possible is one of the plastic Valves inside of the Fuel Supply Pump is not sealing well. The kit for that is sold at Fastlane in the parts tab at the top of the page and is around $11+shipping.

If He did not ream or otherwise clean out the Carbon from the Glow Plug Holes He should do that before Winter so that the new Glow Plugs would last longer.
