This tester is specific to K-Jetronic V8 engines due to the special fittings and adapters it includes. The tester itself may work with other Bosch CIS fuel injection systems, but the included fittings to attach the hoses to the engine will most likely not work.
These instructions are specific to installing the relocation bracket assembly that we offer for the fuel-injected M110 engine. See related products below.
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.
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?
This WUR is very simple in design and has no internal diaphrams. It is also quite short compared to the other types. No instructions are included, but they are readily available on the internet by doing some google searches.
These 8-minute video instructions are now included with Kent's basic and deluxe Version 3 fuel injection pressure tester. You will learn some tips and tricks on how to pressure test a 1976 to 1985 fuel-injected V8 engine using one of our test kits.
This fitting is not included in our deluxe pressure tester or the builder's kit. If you plan on pressure testing your 1976 to 1985 M110 fuel system, this fitting is highly recommended.
This accumulator was unique in the mid to late 1970s. It was used on all 6.9s but only some 450 V8 models. That is why you MUST know which type you have BEFORE ordering. You can clearly see the two threaded holes coming into the front of the accumulator housing.
Almost NLA. As a safety preventative measure, replace this hose if it shows signs of hardening or cracking. This hose is under 90 psi; if it cracks and spews fuel, you can have an instant engine fire.
This video applies to both K-jetronic and KE-jetronic fuel injection engines on Mercedes from 1976 to 1993.. Let's say you just acquired an old gas engined Mercedes and you just can not get it to run right and or even get it to start.
