61x Diesel Vacuum 3/2 Way Valve Troubleshooting and Hose Replacement Kit

All 240D 300D 300CD 300TD 300SD 1980 to 1984

Until now there has been no practical information for the DIYer to know how to test and replace their own vacuum 3/2 valve assemblies. There certainly been no inexpensive hose replacement kits. This new kit by Kent Bergsma solves both those problems. Most of the 3/2 assemblies on old diesels are totally shot and desperately need a complete overhaul. The challenge was to find just the right vacuum hose to make all the sharp bend hose connections without kinking. The solution has been found!
