In this 28-minute video, Kent will walk you step-by-step through the process of fuel, flow, and fuel pressure testing and the M110 engine with Bosch K- Jetronic fuel injection. Please keep in mind.
In this 22 minute video Ken will walk you through the steps of hooking up his injection pressure tester to an M1 10 fuel injected engine, using the modified fittings included in his kit. No testing instructions are included here.
The challenge of getting my tester to work on these engines comes down to the fittings needed to attach the test
This tester is specific to K-Jetronic V8 engines due to the special fittings and adapters it includes. These included M116 and M117 engines in the W116, R107, and early W126 chassis.
This part will fail due to age. It is simple to test with a fuel system pressure tester and easy to install on your fuel rail if you find it has failed.
We guarantee you will be hard-pressed to find a better one than this. Kent has had this in warm storage for the past 25 years, waiting for the perfect car to come along. Look at the pictures carefully to make sure this is a match to what you need. The discs have no cracks.
For the size of these three manuals, the good usable information inside is humongous. If you have one of these diesels, these will get you up to speed and help you get your diesel running better.
This short 7-minute video shows how to use our kit to install a rear crank seal without damaging it.
Take a very close look at the picture. These are all the gaskets and seals you will need to replace if you open up your 722.4 transmission that was produced from 1984 to 1990 for all 6 and 8-cylinder passenger cars that had a displacement of 2.6 liters or more (EXCEPT the 300D and 300TGD.
These original masts are NLA, and this is from Kent's 20-year-old stock and was only used for a few months. No damage. super smooth operation and super straight. The TOOTHED tail was used on some antennas from 1983-84 up until the early to mid 1990s.
Looks like new. Smooth operation and no bends in the mast. These original masts are NLA and this is from old new stock. The smooth tail was used on antennas from the mid 1970's up until around 1983-1985. This would include the W116, R107, early W123, and early W126.
In this 22-minute instructional video, Kent will disassemble a 1979 Fuel Injection Delivery System and show you how he paints the brackets and puts it all back together with new parts. To purchase the kit related to this video, please see the related products below.
Hard to find one of these in good condition. This one is used but in excellent condition.
There is only one of these, and it is so rare that we may not see another. Both parts are no longer available new, and pressure-compensating valves are in high demand. The compensating valve has been opened up and inspected and is in good condition.
Only one available. Check out the before-and-after pictures. Kent redid this unit himself. Study the pictures carefully and note what is not included.
These instructions are specific to installing the relocation bracket assembly that we offer for the fuel-injected M110 engine. The video runs 11 minutes and just gives an overview (not step-by-step instructions) of how you can build a relocation bracket from the parts included in our kit.
When checking your existing fuel delivery system, you may need to remove the plastic shroud for a better look. The key is spotting the "T" with a small-diameter hard fuel line coming off the line between the filter and the accumulator. Look at the pictures below to compare.
This is a builder's kit and will require fabrication on your part. That means strap bending, location testing, bracket drilling, and WUR mounting. The kit comes with Kent's video instructions on how to do this and on how to hook up the electrical connector, vacuum hose, and two fuel lines.
There is no need to purchase this short 4-minute video. It is a wiring update to the electric water pump kit we sell, and this video will be included. See related products below.
If you find your old diesel slow to start after it has been parked overnight or for extended periods, the problem could be a loss of fuel in the injection pump. Let's face it.
Do you need a way to power up some 12-volt accessories in your old Benz and don't want to use the factory fuse box?
You will build this yourself from the components and instructions included.
Why do a fuel system flow and pressure test? Without one, you will not know if your fuel injection is working properly. This is even more pronounced on K-Jetronic engines that incorporate a warm-up regulator. And guess where that is located on the M110 engine?
ONLY one available. We do have a few good used ones left. See below.
STUDY pictures carefully to see if this is a match. Look at part number.
New water pump as shown for your 380SL or 380SE/C. These are getting more expensive by the month!
ONLY ONE Available. These are extremely hard to find in good working order. Good door closing springs included. This is one of the most common leak areas in the vacuum look lock system.
This is a very nice armrest and would be almost perfect if the front of it had not suffered from the normal fading ( in the front) that is so common with the Palomino color. We call it "pinkamino." Please do not purchase if you want perfection.
In this 16-minute video, Kent explains the two upgrades he made in early 2026 to his electronic fuel injector tester. This video is specific to the tester we sell on this website. See related products below.
These are the instructions (3-minute video) for wrapping the door check straps mentioned above with the cover and tape we include with the door checks we sell. See related products below.
4 pieces of heavy black vinyl plastic cut to fit with 4 pieces of the best sticking tape in the world. You can put these on yourself if you install new door checks or remove your old ones for lubrication.
Buy the LED dash bulb variety pack and save $$$. Included are 2 bright white, AND 2 amber bulbs This way you can compare and really decide which color is best for you. You will receive video instructions on how to use the tools to get the dahs out.
This is what helps to hold the cluster tight to the dash. Good soft seal as shown. No cracks or tears.
Good used condition with flexible rubber coupler.
Original fuel filters for these models do NOT come with the right-angle fitting that attaches to the filter inlet (see pictures below). On some occasions, this fitting is missing or rusted beyond use. In that case, you will need a new fitting, but the original fittings are no longer available.
We only have a few of these available from Kent's old stock. When gone, there will be no more. Tension housing and pin have been cleaned and inspected. Excellent condition. New spring and gasket are included. Use of a thread locker on the cap is recommended.
We call this a "short kit" because it is not complete. You will need to supply your own drain hose. The full kit includes 10 feet of thin-wall silicone hose and special urethane sealant. If you want to provide those items yourself, you can purchase this kit and save $$$.
This is the real deal. Used by factory technicians with picture breakdowns and genuine part numbers attached. Published in 1965 in multiple languages. 92 pages long. Covers all engine parts. only
This one is rare and hard to find.
This is one very handy set to have, especially when working on some of the newer engines. You have sooo many options on which pick to choose.
Limited offering. You will get the 123 SEDAN rear seal and Kent's complete installation kit. To learn more about what is included in the installation kit, click on the related product below.
There are two main reasons to install instrument cluster LED light bulbs. They give off more light to the instruments and then run a lot cooler. We offer them for the W124 in bright white and amber. If you can not decide on which color see the images below for a side-by-side comparison.
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.
Straight and bright. This is the actual set you will receive.
If you have an early OBD-1 system and your check engine light comes on, you will need this to diagnose the problem. There is lots of information online on how to do this.
If you try to open up those clutch drums without this tool you WILL be frustrated! You may get them open, but trying to put them back together is something else! If you need instructions or other parts see related products below.
This was removed from a recently rebuilt transmission that was removed from a 1983 300D. I do not know what work if any was done on this vavle body but it was in very good working conditon when removed. SPECIAL PRICE.
This is a short 3-minute tip video on some of the things that are different when removing the rear seal. This is NOT a complete video instruction.
