We want to help you get your diesel performing better. If your injector tips are worn out here are my recommended replacements. These injector tips are made by Monark in Germany and they are designed with a finer mist pattern than that produced by the Bosch tips. These are direct replacement nozzles for your factory Bosch Fuel Injectors. You can replace just the nozzle for better fuel economy, more power, easier starts, and less exhaust smoke.My experience has shown that these tips work better (fuel burn) especially on higher mileage diesels with less than perfect compression numbers. On my own diesels I have also noticed less injector nailing (pinging noise) with these tips installed.

Installation notes: Applicable for all 4 and 5 cylinder diesel engines 1968 to 1985, AND 1984 to 1985 190D 2.2 Only.  If you would prefer our complete manual on injector cleaning and testing CLICK HERE.

Ideally you should pressure test and set the correct release pressure when installing new tips. If there is a Bosch repair facility near by you can have them do this testing/adjusting for you. You can install these tips without checking adjustment and in many cases they will fall into an acceptable pressure/spray pattern range. This might be preferable to badly worn out fuel injectors - but best to test pressures to know for sure.

NOTE: If you are running SVO WVO or B100 these have the highly touted DN OSD 261 specification. Many, including myself, have reported great results with these nozzles when running heavier viscosity fuel.

Heat shields washers should be changed everytime you replace an injector. They are NOT included with this nozzle. CLICK HERE to order injector heat shields.

I recommend you have a torque wrench handy when rebuilding your injectors. If not we offer one at a great price. CLICK HERE to order.Use a torque wrench when cleaning or rebuilding injectorsUse a torque wrench when cleaning or rebuilding injectors

 

 

HIGHLY RECOMMENDED: You will need some fine sandpaper to lap in your injector parts during rebuild. We have an kit available separately that will assure your injector halves don't leak when you put them back together.  Instructions and tips are included.  

Note: This kit can also be used to fix a pesky leak on your existing injectors CLICK HERE to order separately.

 

 

WARNING:

The health and longevity of your new Monark injector nozzles with be directly affected by the cleanliness of your diesel fuel and its lubricity. Any gunk or crude in your filters or injection pump could travel to the new nozzles and cause scoring leading to premature failure (our warranty does not cover nozzle tip scoring). The following procedures are a MUST with installing new nozzles:

1. Diesel Purge

Run at least one can (two if you have never done it) of diesel purge through your fuel injection system before removing your old injectors.

 

 

 

 

 

 

2. Change Filters

Change both your pre and main fuel filter. Click Here to view all filters.

 

 

 

 

 

3. Use Fuel Additive

The new ultra low-sulfur  (ULSD) diesel fuel available at the pumps is not kind to mechanical fuel injectors. The sulfur was the key ingredient used to keep your fuel pump and fuel injectors lubricated. To protect your new nozzles we recommend you add a high grade fuel additive to your fuel (such as Lubro-Moly Diesel Hi-Test)
