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). To fix this high pressure leak requires taking the injector apart and "lapping" the mating surfaces. Seal is by metal to metal contact. There is no o-ring or gasket inside the injector.

This kit includes three grades of fine sandpaper and complete lapping instructions. In some cases of very slight fuel seepage a special anerobic sealant can be used to stop the leak without taking the injector apart. We include a small tube of this special sealant along with tips on how to use it successfully!

This little inexpensive kit is guaranteed to save fuel and put a smile on your face!

Troubleshooting an annoying shift problem must first start with the vacuum modulator. This vacuum control unit mounted on the side of the transmission must be tested and adjusted to specs BEFORE you move on to other adjustments. Unfortunately this can not be done by guess or by feel. There is a pressure port on the side of the transmission that you must tap into and connect to a pressure gauge. The engine must then be started and the modulator adjusted to a set pressure for that specific transmission. It is not a difficult job with the proper test tools and information, and can be done in less than an hour. Too much pressure and abrupt shifts will occur. Too little pressure and you may experience slipping or flaring during shifts. My kit with help you do all the above with ease.

Brand new coolant pipe for early 123 chassis diesels. Located on the water pump housing. Will fit some later models but please email with vin number to confirm fit.

Welcome to the first inexpensive CIS fuel injector tester for the home mechanic. This bench mount tester will allow you to check the release pressure and spray pattern of your injectors. It will not accurately measure quantity of fuel delivered nor the release balance between the injectors as do the big commercial test units. With a little practice you can get a "feel" for balance by quickly testing all injectors one right after another and analyzing spray patterns. CIS injectors are spraying all the time in your engine. There is no way you can get this hand pump to spray continuously, but by pumping rapidly and can get a fairly good idea just how well each injector is atomizing the fuel. 

With this conversion kit you can use your current Mercedessource diesel fuel injector tester to test Bosch gas engine fuel injectors on 450SL, 380SL, 560SL, 280E, 280CE, 280SE/L,450SE/L, 380SE/L, 500SE/L, 380SEC, 420SEL, 560SEL, 560SEC, 300SE/L, 190E 2.3, 190E 2.6, 260E, 300E, 300TE, 300CE, 300SL, and 500SL.

Rubber fuel injector seal fits the models listing in the subtitle above. These should always be changed when replacing fuel injectors. They are also one of the most common sources for intake air leaks causing high idle speed and rough running.

Bushing that holds fuel injector into the head of the engine. These get very brittle with age. If you are planning on removing your fuel injectors I highly recommend you order these to have on hand. Even if you only plan to remove and clean your injectors there is a good chance you may break one or more of these holders. Retail price $6.00 ea.

Holder includes outer 0-ring seal but does not include seal bushing at the top of the injector. These also be hard and lose their seal with age. Failure can cause high speed idle and rough running. CLICK HERE to order these seals separately.

Now available as a cost savings kit! Eight new Bosch CIS fuel injectors with eight holder bushing O-ring seals. If your 1986 to 1991 8 cylinder has over 120,000 miles and you think your injectors are ok then you might want to think again. I have been amazed with the poor results of our recent testing of large number of fuel injectors from various gas engine models ( 1977 to 1993). Less than half of those injectors tested passed a simple spray pattern and leak test. Unlike diesel injectors there is no way to take them apart, adjust, or rebuilt them. It is possible to send them out for ultrasonic cleaning but in cases where cleaning does not help your only option is to replace them.

This is critical rubber part that seals the fuel injector to the injector holder. Deterioration can result in high idle speeds and poor engine performance. Unless you have a low mileage car with soft seals, these should be changed when testing, cleaning, or replacing your fuel injectors.

This is the plastic fuel injector to intake manifold insulation holder. It is not necessary to replace this part unless the end is damaged or deteriorated. A bad holder can affect engine performance.

Brand new 02 Sensor removal socket. 3/8" drive with 22 mm 12 point open head. Fits Mercedes 201 190E 2.6 ONLY and 124 chassis 260E 300E 300TE from 1984 to 1990.

02 sensor replacement is one of those neglected maintenance items. They really should be replaced every 100,000 miles for peak engine performance. If left in too long they seize in the threads and are impossible to remove with a standard open end wrench. This special socket will remove even the most stubborn sensors. 

We also sell a universal Bosch 02 sensor for above models at a great price! CLICK HERE to view sensor.

Socket works due to a cutout that will allow you to slip it over the wire harness:

This is the part you need when your ignition key continues to stick even after installing a new tumbler assembly. In over 70 percent of the cases involving a severely sticking key, I have found you need to replace both the tumbler AND the steering lock if you hope to have a lasting repair. They tend to wear each other out if the problem is not corrected early on. In cases where the key just begins to stick slightly while turning, you can sometimes get by only having to replace the tumbler assembly.

If your key gets stuck or tumbler fails will have to drill out your ignition lock to even move your car. When this happens you are better off buying a complete new assembly. You won't even be able to get tumbler or the black cover cap off your old assembly.

We make it easy for you by providing a new assembly that Kent assembles in his shop before shipping. This includes installing a new tumbler assembly and black cover cap. A new ignition switch is included but you will have to use the three screws from your old lock to secure the new electrical switch. A new vacuum cut-off switch is also included and installed.

Includes 30 quality red plastic clips, a removal tool and detailed instructions. There are a number of reasons why you would want to remove the center side trim on your older Mercedes. You may just want to clean and detail behind them (it does get pretty dirty back there over the years). If you are repainting your car removing the side trim is a must for a quality job. There could be rust growing out of the holes on the back side of the strips (do not let this go - see my Miracle Rust Cure products). Or you may have one or more loose or damaged side strips. The biggest problem in removing these strips is that the plastic snap clips often come off with the strip hold down pins.

If your shutoff valve is leaking oil or is not shutting off quickly (even with a good valve and proper vacuum applied to it) you may need to remove it for repair. You can adjust its travel with the items included in this kit. Comes with 2 new gaskets, proper gasket sealant and instructions for adjustment. Does not come with instructions on how to remove and replace the valve but that is done is readily done by removing the four bolts that hold the valve to the back of the injection pump.

Quality breaker bar from Taiwan. 25 inches long, one half inch drive. Is built with chrome vanadium steel construction. The drive head swivels 180 degrees. When working on Mercedes there will come a time when you need a lot of torque to remove a stubborn or very big bolt (like from crankshaft bolt). When this happens you need a LONG breaker bar. Even removing head bolts can create a sweat if you don't have the leverage. This is a very nice tool for the price.
