Works on all models from 1977 to 1993 with the Bosch C.I.S Fuel Injection system - see models listed below: Now you can do it yourself on the bench with this inexpensive tester- Save big $$.  Ever wonder how well your old CIS fuel injectors are working?

If you acquire an older Mercedes diesel and want to test those large Bosch injectors with your V3 gasoline bench tester, you  will need 4 things to complete the conversion: 3000 PSI gauge, our new capture bottle to hold the larger injectors, injector sealing kit, and Kent’s written manual and vid

We know that many of you own multiple Mercedes, including both gas and diesel models. If you own one of Kent’s fuel injector pressure testers you no doubt will want to test all your applicable mechanical fuel injectors in both types of older engines.

Works on the following:  6 cylinder gas MFI engines 1959 to 1972, 6.3 and diesel engines 200D 220D 240D 300D 300TD 300CD and 300SD through 1985. 

These will fit W108, W109, and W111 with the very early 3.5 V8 engines only. WARNING: MAKE CERTAIN your current injectors are yellow at the top. A restocking fee will apply if you pl

We think almost all these old M119 V8 engines need to have their fuel injectors replaced for peak performance and better fuel economy. We also believe an old fuel pressure regulator should be replaced so we are including one at no additional cost.

This will give you everything you will need ( except 12-volt power and cleaning fluid ) to bench clean and test your D-jetronic fuel injectors in your own garage or workshop once they are removed from the engine.

Fits the following: All 4 cylinder diesel engines from 1968 to 1985, including 201 Chassis 190D 2.2.  For 220D 240D and 190D 2.2 Engines - FREE heat shield washers - PDF download instructions included.

Fits the following: All 5 cylinder diesel engines from 1975 to 1985. For 300D 300TD 300CD 300SD,  PDF instructions included. This is the critical inside wear part of the injector that delivers the fuel spray into the cylinder. These are direct replacement new fuel injector nozzles from Bosch.

DO NOT ORDER UNTIL YOU REMOVE ONE INJECTOR IN YOUR ENGINE AND INSPECT THE HOLE. Sometime in 1974, Mercedes changed the way these injectors were sealed into the head to prevent air leaks. A "YELLOWISH" nylon sleeve was added along with two seals on the lower end of the fuel injector.

This is the FIRST thing you should do on your D-Jet V8 engine. Rather than explain everything in this kit and what it can do for you, watch Kent's YouTube video below.   If you don't do this, you will be guessing and spending money forever trying to get the engine to run right!

The original screws in these pumps get pretty nasty looking over time. When you try to clean them will a wire wheel the plating will be completely removed and the heads will rust again pretty quickly. Now you can install new original looking yellow zink plated screws and washers.

Since new original style pumps are no longer made, this is the best way to finally fix your old fuel pump leaks and poor performance. This kit is designed specifically for the W108 and W109 small V8 sedans.

These are high quality German brand filters. Since mose of these cars are not driven regularly Kent recommends an oil change every 5000 miles or 2 years whichever comes first ( using quality oil) and a fuel fitler change every 10,000 miles or 2 years whichever comes

This is our most complete FID kit yet. Kent wanted to make sure you would have all the parts you need including hardware.

DOES NOT INCLUDE ANY METAL FACTORY HARD LINES!!! What you SEE in the picture is exactly what you will receive. Many of these particular big V8 models are now becoming true collector cars and going up in value at a steady rate.
