Kent's Factory Service Manuals collection is going on sale now. CLICK HERE.
Kent's procedure uses the factory recommended "drip tube method" but with a "twist." He has devised a way to get accurate and consistant IP timing results while trying to get the drip tube to drip at one drip per second exactly when it should!
Any time you are removing and replacing your fuel injectors you will need to change the return hose and the heat shield crush washers. If you don’t, you will have leaking hoses and possible compression leaks at the injector nozzles.
Kent has never seen fresh fuel hoses on all the old MFI Mercedes he has worked on over the years. They only seem to get changed when they start leaking. Leaking fuel hoses at the electric fuel pump is a fire hazard!
Leaking fuel injector pumps have become a very common problem in the 60x. engines produced from the mid 1980s to the mid 1990s. The early 60x.
5/25/22 update: The precision nozzles included are now made for us by Wolfswerke-sachsen ( same company and same nozzle that was formerly branded as Monark). Yes!
Keeping your injectors clean and tuned is one of the best ways you can improve mileage in a diesel. Buy both Kents new manual Diesel Fuel Injector Cleaning and Testing Procedures and his Top Brass Custom Cleaning Tool Kit and save!
This is the best way to determine if the expensive injection pump is going to work for old 4 AND 5-cylinder diesel engines that have not run in years. Watch the video below to understand what this kit can do.
Watch the video below to understand what this kit can do. Ensure your injection pump is thoroughly cleaned and lubricated before starting the engine after long storage.
This is the most complete 1970 to 1975 V8 injector repair kit you can find anywhere.
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.
With the required pressure tank you will be able to individually test and clean our D-jet fuel injectors. Along with a 12-volt power source, you will need I gallon of cleaning fluid as described in the instructions.
This is every thing you need along with free video instructions by Kent Bergsma. Why change the K-jet fuel injectors in your M110 engine. One thing is they are very old. Second this is right now they are readily available and resonably inexpensive.
This kit will not fix all your pump problems. If the motor is worn or burnt out, this won't help. But if the lower impeller is "stuck" due to lack of use and old fuel, then this could be a simple fix. In the video below, Kent will explain what this kit can fix and why it is needed.
Did you hear these are not available? No part number anywhere? Well, as the source we went to work and made it happen. You can now purchase the correct copper sealing rings for your OM616 and OM617 injection pump delivery valves.
Most 1988 to 1993 6 cylinder CIS fuel injection delivery (FID) systems are old and tired and have not been properly maintained. These include the W201 190E 2.6, the W124 260E 300E, 300CE, 300TE, the W126 300SE, and 300SEL, and the R129 300SL.
Those old hardened and discolored plastic fuel hoses in your diesel engine compartment probably need to be replaced. When they crack and break you can dump a ton of fuel out on the road before your engine quits and leaves you stranded.
This kit will give you everything you need to fix the leaking or aged Tee hose between the fuel damper and the fuel accumulator on most 1977 to 1980 fuel delivery systems. Watch the video below to learn why this is needed.
It was difficult to find a filter to fit the correct size outlet hose. Install this steel 10-micron filter in your fuel tank outlet hose to protect your fuel pump. Clamps are provided along with a pull to plug the fuel hose temporarily to reduce fuel spills.
PLEASE LOOK AT YOUR SYSTEM BEFORE ORDERING to confirm the type of accumulator you have. ( Watch the last video below for examples )For systems with ONE HOLE ACCUMULATOR only. Some 450SL, 450SLC, 450SE, 450SEL with 4.5 and W116 280SE .
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.
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.
This easy-to-install kit could do wonders for your older diesel engine. The lift pump is almost always forgotten when it comes to maintenance on the OM616 and OM617 engines.
Kent has sourced 2 special Viton o-rings for the outer pump housing on these early djetronic Bosch electric fuel pumps. There are two orings that harden with age causing the pump to leak fuel at the outer end of the pump.
This is a "must-have" kit when adjusting release "pop" pressures on older diesel mechanical fuel injectors. It is the internal spring "shim" thickness that determines the exact pressure required for the release of fuel at the tip of the injector.
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.

With these old gas fuel injectors, sometimes you just have to "back flush" the insides to restore them to peak performance. There is no guarantee that back flush cleaning will restore every old gasoline mechanical fuel injector. Some are just plain worn out.
These early “short style” electric fuel pumps are very prone to leaking fuel because the rubber case o-ring seals harden with age. New pumps are no longer available and rebuilt are VERY expensive! If you risk buying a used one it will probably end up leaking or seeping fuel too.

This is something many owner's and mechanics miss. That little check valve on the side of the injection pump can cause a lot of starting problems on the older diesels.
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.
We receive a large number of emails from customers complaining about small fuel leaks at the fuel injector housing (coming out the threads between the two halves)and how best to seal them. To fix this high pressure leak requires taking the injector apart and "lapping" the mating surfaces.
Leaking fuel injector pumps have become a very common problem in the 60x. engines produced from the mid 1980s to the mid 1990s. The early 60x.
