The FLOW or low pressure method of checking and adjusting injection pump timing does not require a separate pressure tank. With this method you use the hand primer pump to pump up pressure in the injection pump to get fuel to flow out of the half round drip tube included in this kit. This is a simpler method of setting your injection pump timing, but not as accurate as the HIGH pressure method.

Let Kent explain the reasons for the two methods and when he prefers using each one. Click on the arrow in the center of the picture above to watch his YouTube video.
If you want faster and smoother cold starts, easier bleeding, and more power under load, consider installing an electric fuel boost pump inline between the fuel tank and the injection pump on your old diesel. It takes the strain off the mechanical lift pump, which is always trying to suck fuel up to the engine from the tank. Other diesel manufacturers have done this! See related products below for our inexpensive and easy-to-install DIY kit.
