These will fit W108, W109, and W111 with the very early 3.5 V8 engines only. WARNING: MAKE CERTAIN your current injectors are yellow at the top. A restocking fee will apply if you pl

These will also fit the 1972 U.S. version 350SL with the 4.5 engine. Just make sure of the correct color. WARNING: MAKE CERTAIN your current injectors are blue/green at the top. A restocking fee will apply if you place an order in error. These are for the 4.5 engine only.

These plugs will NOT work on your original injectors. They will ONLY work on our new replacements (see below). These plugs are a good alternative to the damaged originals on your D-Jetronic fuel-injected engine only if you are installing our new injectors.

ALERT! If you are having a hard time keeping your good hoses from leaking, DO A PRESSURE TEST!  The system is designed for 30 psi. If your pressure regulator has failed, no amount of tightening your clamps will solve the problem.

The original fuel filter has a rigid right-angle fitting, as shown in the pictures below. We do not provide this fitting in our fuel delivery kits as more often than not it can be removed from your old filter and installed in the new filter we provide.

Let's face it. These fuel tanks and now 50 years old and most are not squeaky clean inside. There is a fuel tank screen that will catch most particles if the screen is in good shape. But I have found that it will not catch the very fine rust particulates that are so common in these old cars.

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.

Original fuel filters for these models do NOT come with the right-angle fitting that attaches to the filter inlet (see pictures below). On some occasions, this fitting is missing or rusted beyond use. In that case, you will need a new fitting, but the original fittings are no longer available.

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 is one part that is very subject to corrosion and leaks around the base. When the actual part fails, included our new stainless bolts that won't corrode with instructions on how to carefully get the old corroded bolts out.

New in April of 2026. This is the "whole ball of wax," including 10 free on-demand training videos.  Kent put this kit together for those enthusiasts who own multiple classic Mercedes from the 1970s through the 1990s. Fuel Injection back then was not as reliable as it is now.

It is always good to have two of these when working on cooling system components or fuel system components.  You could clamp off both sides of the hose so you can easily remove the component without losing fluids.

Since these engines run so well, some believe that the fuel injectors will last forever. If you have noticed your fuel economy is declining or your engine oil seems thin, then replace these injectors.

If you plan to change coolant hoses this is a must-have labor-saving tool. These are cleverly designed tools. I could not have done it better myself. I actually use to make a couple of different types before I found this set.

Four new Continental belts with detailed video instructions. You should consider replacing the following at the same time, as they are commonly due to age and neglect.

If you own one of the early Mercedes overhead camshaft engines from the mid-1950's up to the mid-1970s that have mechanical (non-self-adjusting) lifters this is a MUST HAVE tool! It does NOT work on the M110 twin cam engine.

Excellent quality zinc plated hose clamps as shown. These can be tighten with a straight blade screw driver or a 7mm socket or nut driver.
