A very efficient fuel pump with good volume output at low psi. Open box and tested, so it has had fuel run through it for video purposes. Less than 20 minutes of run time. Comes with mounting bracket and fittings for 3/8 inch fuel hose, as shown.
Plug into any 120 volt outlet. Sticks strong to the pan. It can be easily removed by prying off with the included tool.
These are the exact units you will receive with the fittings attached as shown. They have been tested, so some fuel has been run through them, but they have not been mounted or used in a vehicle. There are no instructions included.
Last one. Motor may be a different color form what is shown, but still the same unit.
This is the veggie heater that was commonly used during the height of the veggie oil craze (2004 - 2012). This has been used lightly and is still in good working condition. No instructions. Must be operated by a separate electrical circuit with a relay activated.
You'll receive two SPECIAL outlet hoses, one slightly larger than the other, each approximately 12 inches long. The smaller-diameter hose was used on the D-JeTronic models up through 1975. The larger hose was used on most models from 1976 up to 1995.
This short 6-minute video is specifically geared toward using the kit we offer on our website to make your own fuel tank outlet hose. As of August 2026, some of these hoses are no longer available, and others are becoming scarce.

Good condition. No damage, dents, or cracks. This is the actual part you will receive.
We also offer these rings in a complete valve body cleaning and repair kit. See related products below. The accumulators are not difficult to remove from the valve body. NOTE: This kit will contain more rings than you need.
If you have an early 722.3 transmission you are working on, his is the reseal kit you need if you have it out of the car and want to fix and/or prevent external seal leaks. Replacing these seals and O-rings is not difficult except for the B1 piston over and the shift shaft lip seal.
Kent will demonstrate how to use his V-belt pulley rust repair kit in this video. Doing it by hand can take forever!
Kent tried a bunch of methods, but using an electric drill with these round brushes and extension proved to be the fastest and most efficient way to get the rust off those old pulleys that have sat for a long time. Hand wire brushing does not work, and hand sanding takes a long time.
In this 10-minute instructional video, Kent will demonstrate how to use fiberglass cloth and POR15 to patch a small hole in the rear muffler. This will not work on catalytic converters as they get too hot, but can be used on center and rear mufflers to add a little more life.
If you find spots of rust on your old Benz, you should address them right away.If you want a long-lasting rust repair, preparation is key. The application is straightforward, but there are some potential problems you should avoid.

Why rebuild a 722.3 valve body? Some may have told you just to "leave it alone." It can be a little intimidating, especially if you have visions of all kinds of springs, balls, and little valves flying all over the place when you take it apart. Watch the video below for a short overview.
In this 7-minute video, Kent will explain the process and show you how to hook it up to your transmission and get a good reading. For accurac,y it is best to have the transmission warm, so take it out for 15 to 20 minutes before you hook up the gauge under your car.
Why have a separate tester just to measure the full pressure running inside the transmission? For this test, the pressure can reach up to 240 psi and can go higher if there is a restriction. This requires a special gauge and hose that can handle the pressure.
In this 28-minute video, Kent will share with you some of his secrets on testing and adjusting the warm-up regulator on a 1976 to 1985 Mercedes K-Jetronic fuel-injected engine. A fuel pressure testing and his special kit will be required to complete all tasks.
This WUR has two vacuum connections on the bottom. This style of WUR started showing up in the late 1970's. It was not installed on all vehicles. You have to look at the WUR on your engine to determine what you have.
