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!

While working on the fuel injectors of a 240D this week, Kent finally decided he had had enough. After 20 years of fighting those fuel injector return hoses he decided he just had to come up with a tool to make the job easier. 2 hours later the tool was designed and the prototype made.
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.
If your fuel level gauge is not reading accurately or the needle jumps around and or your car’s low fuel warning light does not comes on, it is usually a problem with the tubular sending unit in the fuel tank.
If you think CIS fuel injectors can just be ignored, think again. Sure, your gas engine will continue to start and run “ok”, but you may find that it is not producing the power it once did nor the fuel mileage it once delivered.
Works on all models from 1977 to 1993 with the Bosch C.I.S Fuel Injection system - see models listed below
The timing device installed in the W115, W116, W123 and early W126 with OM615, OM616, and OM617 engines from 1986 to 1985 is somewhat a mystery to many owners.
If you are new to older Mercedes diesels and have not worked on them before, this is one of the first things you want to learn. Especially if you ever run out of fuel. Without knowing how to do this you will never get the engine started again!
For all MBZ diesel engines 1950 to 1993. These are built at the Mercedessource shop to control quality and production demands. Each one is tested here in our shop before shipping.
If you have been reluctant to overhaul your worn our diesel fuel injectors because the job is too difficult or too costly then think again!
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!
FITS all 116 123 Diesel and Gasoline, and 126 chassis from 1977 to 1985. Finally a socket to remove your fuel tank screen that really works. Most correct size sockets tend to be SO BIG that they require 3/4 inch drive ratchets and extensions to use them. Who has those in their tool box??
When it comes to cleaning diesel fuel injectors, and yes they do need periodic cleaning, there is nothing like having the right tools to do the job.
When removing the main fuel filter you need a wrench that is usually not included in most tool sets. Ours is high quality made in the USA and will easily remove the filter bolt without rounding off the corners. Works on W116 and W126 300SD and W123 240D, 300D, 300CD, and 300TD.
Exceptional injection pump as shown. Will include the injection pump, lift pump, all hard plastic fuel lines, complete main fuel filter assembly and good working vacuum shut off valve on the back of the pump. Please note does not include the metal fuel lines going to the injectors.
Good used unit with the center bolt. Hard plastic lines can be used. Rubber hoses and center bolt seals with need replacing. Not damaged
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.
This is the best tool to use when installing or removing the Monark hand primer pump. PLEASE NOTE. This is 19mm and will NOT work on the Bosch hand primer pump or other style pumps (most others are 17 mm).
This is a brand new Genuine Mercedes check valve for the fuel injection pump on 4 and 5 cylinder diesels 1977 to 1985. This valve is mounted on inside of pump in the fuel line going to the filter.
This 24 minute on demand training video comes with our injector back flush cleaning kit. You can purchase this video separately, but please keep in mind you will not have any of the tools or supplies to complete this procedure yourself.
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.
This video is included free with the purchase of our check valve overhaul kit. Please see related products below
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.
When any part of the overboost protection system fails, your turbo diesel engine can lose power or start to smoke too much.
Want to get more power our of your 5 cylinder OM617 turbo diesel? Maybe you will like to reduce the dark smoke coming out the tail pipe during heavy acceleration?

Here is a wrench I should have made 15+ years ago. I can not believe how much time and frustration I would have saved over the years working on all those 100's of Mercedes diesel engines if I would have done it!
This clear 16 oz. bottle and hose is the safest way to test of clean your older gas and diesel injectors by not having to breathe the harmful fumes produced by the fine mist spray. NOTE: This only works for mechanical fuel injectors. It is not intended for electrically operated fuel injectors.
The FLOW pressure method can be used to both check and set injection pump timing. Personally, Kent likes to use this method only when checking if the I.P. needs adjustment.
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.
If you have had to remove any of the banjo bolts you can see that those sealing rings are getting quite old... when you see scoring in the ring the ring appears to be crushed, they should be replaced to prevent leaks and to prevent air from getting into the fuel lines.
This is a collection of SPECIAL tools Kent has put together to help you grab, twist, and pull on things in and around your Mercedes. He makes each one of these tools right here in his shop.
Kent put together the three most important products you will need to use his pressurized method of setting the critical timing on your diesel engine injection pump. This is often negelected and when corrected can lead to faster starts, better fuel economy and less engine smoke.
This one hour long on demand video is included free with the purchase of Kent's OM61x injection pump timing kit. The method he teaches uses his own kit, his custom built pressure tank, and his special IP snake wrench.
Another wrench designed by Kent Bergsma and born out of frustration. This could be the weirdest wrench anywhere in the world! While shooting a video on adjusting the injection pump timing on an older Mercedes diesel Kent ran into a big problem.
This unique tank not only functions as an emergency fuel tank, but it can also serve to help troubleshoot diesel engine performance problems as well as complete a clean and efficient diesel purge.
33 page digital PDF manual. Applies to all 110 115 116 123 126 201 124 140 diesels from 1961 to 1994. From my many years of working professionally on Mercedes diesels I have learned fuel injectors are the single most neglected maintenance item. I believe there are a number of reasons for this.
The original fuel lines on most late 70s and early 80s Mercedes Diesels were braided line and with age they do rot and develop slow leaks.
Superb product for cold weather diesel operations. This electric pad heater wraps around filter and connects to cars electrical system. Easier startup, more power, longer filter element life - prevents freezing of water particles in filter a sub-freezing temps.
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.
Good used factory hard fuel line as shown. These are prone to cracking right around the top nipple and dumping fuel on the road. Check yours today!
New Bosch fuel filter as shown. Before ordering please make certain that this fits your Benz. Not all gas fuel filters are created equal.
ONLY ONE LIKE THIS AVAILABLE! Good used mechanical lift pump removed from an engine with only 110,000 miles. If your engine is lacking in power or rough running even with new filters and clean fuel, you may have a problem with this pump.
New Factory type spin-on fuel filter. This is for one (1) filter in the box. Does not include instructions or sealing ring and o-ring for center bolt. Fits all 123, 116 and 126 4 and 5 cylinder diesels from 1977 to 1985.

From all my years of working around engines the one thing that absolutely drives me crazy is barbed hose fittings. This even got worse in recent years as many SVO WVO kit makers would send our their components with barbed hose fittings!

Fits 116, 123 and 126 chassis diesel 1977 to 1985 only. We have been sourcing these copper washers from Mercedes Benz and also including o-rings for a long time with our fuel filter kits, due to the fact that they do not come with the fuel filters.
Factory fuel hose that goes from the fuel tank strainer to the metal feed pipe just above your rear axle. Fits all 116 diesel 300SD, and 123 240D 300D and 300CD and all 126 chassis diesels 300SD 300SDL 350SD/L.
These are my favorite German hose clamps. They tighten securely, dont cut into the hose, and don't rust or break. If you are working on the fuel system of any Mercedes I recommend you have these clamps on had.
