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.

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. 

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.

Set of 8 correct size bolts and washers to spruce up the engine compartment of your D-jetronic V8 engine. Watch the videos to see how these actually look installed. 

This will give you everything you will need ( except 12-volt power and cleaning fluid ) to bench clean and test your D-jetronic fuel injectors in your own garage or workshop once they are removed from the engine.

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.

The original screws in these pumps get pretty nasty looking over time. When you try to clean them will a wire wheel the plating will be completely removed and the heads will rust again pretty quickly. Now you can install new original looking yellow zink plated screws and washers.

If your fuel gauge stops working or is not reading accurately, many times it can be repaired by removing it from the fuel tank, taking it apart and giving it a good internal cleaning of the contact points, float shaft, and wires.

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 kit is designed specifically for the W108 and W109 small V8 sedans.

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.

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.

NOTE: Ships UPS ground only. Select ground for entire order to save in shipping costs. I am a great fan of LubroMoly products.

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.

I have used a lot of different clamping tools over the years to prevent fluids from leaking out when removing coolant, fuel, or brake fluid hoses. Most work ok. Some are hard to use in tight places.  Many do not stop every last drip from coming out of the hose.
