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.
For all MBZ diesel engines 1950 to 1999. Designed by Kent Bergsma. These are built at Mercedessource to control quality and production demands. Each one is tested here in our shop before shipping.

When “rebuilding” an old Bosch mechanical fuel injector, replacing the nozzle is usually enough get it working again at peak performance. But sometimes you will run into a fuel injector that just won't fire right nor product a correct fan spray pattern.
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!
Fits all Diesels from 1965 to 1985
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.

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.
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.
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.
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 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.
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.

PLEASE NOTE THE FOLLOWING:
PLEASE READ CAREFULLY. This line will not fit the 601 602 and 603 diesel engines produced from 1984 to 1995. If you order in error this part is not returnable. See applicable models and years in subtitle. We had this new straight hard line specially manufactured for us in Germany.
In working on many 61x series diesel engines, I have often found one or more of these clamps missing. Missing or loose clamps are the number one reason for injector hardline crack failure. There should be a clamp like this between every two hard lines to minimize vibration fatigue failure.
This is one of Kent's favorite tools. Lets you reach into tight places - very long nose curved pliers with teeth - like hemostat. With the locking handles it is amazing what this clamp / pliers can hold - and the tight places it can get into!
Rough running diesels abound everywhere. The symptoms include poor acceleration, no power, and excess exhaust smoke. Some times these can be a sign of real problems. Other times it may mean your fuel injection system just needs a good cleaning. And NOTHING cleans better than Diesel Purge.
Good used injector housing for parts or for rebuilding. Does NOT include the nozzle. This is a core part only and will not work in the engine without new nozzle installed.
This video only applies to our injector pressure tester. Kent will show you how to attach the capture bottle and fittings to your older Version 1 or Version 2 pressure tester. Video is free with purchase of the conversion kit.
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.
You would be amazed at how much fuel can leak out of a fuel hose when you disconnect it from your tank or engine. This is an easy way to prevent messy spills.
