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!

This kit will allow you to remove your old fuel warmer and completely bypass it with the parts and instructions you will receive in this kit.
Mercedes installed small fuel warmers on these engines using engine coolant to warm up the fuel just before it enters the injection pump. The idea is great - especially in cold climates, but in moderate and warmer climates it is probably not needed.
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.
MFI (mechanical fuel injection) fuel pumps are notorious for leaking fuel. Leaks are almost always due to age hardened and deformed o-rings inside the pump. Taking the pump off the car, taking it apart, cleaning it and installing new seals will almost always solve the fuel leak problems.
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.
Most owners do not have a big enough hex wrench to remove the fuel tank screen on those models that had the fuel tank right under the rear trunk floor. But the screen does need to be removed, inspected and cleaned due to the age of these cars.
Would you like to find out how well your old (1959 to 1972) mechancial gasoline fuel injectors are working? Now you can do it yourself at home with our custom bench mount hand pump pressure tester and cleaning kit. These are the full instructions that come FREE with the kit.
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 need a good tank for your 126 diesel then this is it. Please note, does not come with a cap or fuel level sending unit nor does it come with a fuel tank screen or hoses. Those items can be ordered separately or you can use them from your existing tank.
Kent uses his 1976 240D that had sat idle for 6 years to demonstrate what needs to be done to get an old fuel system cleaned out and serviced properly. This always includes installing new fuel filters and sometimes will require replacing some of the rubber hoses.
This is a common occurrence as these gas engines with Bosch C.I.S. fuel injection age. Most of them are now at least 20 + years old. The problem goes something like this. You start the engine cold and it will hardly run. It runs rough and idles very low and will even quit a few times.
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.
Brand new Bosch Fuel Injector as shown. This is the later style with the smaller threads. It will only fit the models listed below with CIS fuel injection. How do you know if you have CIS? If you have hard metal fuel lines going to your injectors with no wires you have CIS.
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?
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!

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 pump fits W116 300SD, W126 300SD, and the turbo W123 1981 to 1985. New check valves and seals installed. It comes with a very good used operational Bosch hand primer pump. Gasket included. This mounts to the bottom of the Engine-driven injection pump.
This new gasket is required when replacing the lift pump which is mounted on the lower left side of the fuel injection pump. This is the unit where the hand primer pump is located. To see out lift pump overhaul kit please see related products below:
This is a perfect fit for the O.E. copper sealing ring. You only need one but we sell these as a set of two so you will have a spare.
This is where this sealing ring is located. On top of the fuel injection lift pump and at the base of the hand primer pump:
This is the large o-ring seal for the bottom plate on the early style long electric fuel pump. You will only need one oring but you will receive (2) so you will have a spare in the future. In the video below Kent will explain why you might need this seal.
ONLY ONE AVAILABLE. Good used center section and electric motor as shown. You will have good wire and brushes and a good armature as shown. Use your existing pump for the lower section and assembly hardware needed to restore your pump. See our reseal kit below.
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.
