1960 to 1986 4-cylinder Diesel Injection Pump De-gunking and Equal Flow Test Kit

Store > Fuel Delivery Products > MercedesSource Kits
New version Dec. 2025. Includes special clear inspection hoses, and vented bottles to catch the fluid and measure equal flows.

You attach these to your 200D, 220D, 240D, or W201 190D engine and turn the engine over with the starter motor for cleaning and testing. These can be used for various purposes. This is the best way to determine if the injection pump will perform properly for old 4-cylinder diesel engines that have not been run in years. It will also allow you to purge (clean out) old gummed-up injection pumps. And, finally, you can test for equal flow from the pump by measuring the quantities of fuel in each bottle. Watch the video below to understand what this kit can do and to ensure your injection pump is thoroughly cleaned and functioning on all five cylinders before starting the engine after long storage.

Product Details

kent explains how it works

You will get four clear hoses, each 12 inches long, attached to four small clear bottles to catch and measure flow.  Of course, if you have a four-cylinder engine, you will have a spare unit. NEVER USE GASOLINE to clean or test the pump in this manner. Kent prefers 80 percent carb cleaner and 20 percent automatic transmission fluid as a cleaning agent and a straight diesel fuel for testing.

The bottles are vented at the top lip to prevent pressure build-up. Attachment is via a push-on silicone tube and hose clamps as shown below. The included on-demand video instructions provide examples of how to use this kit.
