This pump fits W116 300SD, W126 300SD, and the turbo W123 1981 to 1985. Fully disassembled and inspected. New check valves and seals installed. A lightly used, good-working Bosch primer pump is included. NOTE: We can no longer get the gaskets, but you will receive a pattern and gasket material so you can make your own along with gasket sealant. The picture below will show you the fitting that is missing. It was lost during overhaul. A new check valve in spring and copper ceiling ring are included and should be installed as per the picture below. You will need to remove the threaded fitting from your existing lift pump and install it, then tighten it down on top of the check valve spring. Be sure to use the new copper ceiling ring included.
Product Details
This pump mounts to the bottom of the Engine-driven injection pump and is critical to power output, solid starts, and good fuel economy. NO instructions included.
If you want faster and smoother cold starts, easier bleeding, and more power under load, consider installing an electric fuel boost pump inline between the fuel tank and the injection pump on your old diesel. It takes the strain off the mechanical lift pump, which is always trying to suck fuel up to the engine from the tank. Other diesel manufacturers have done this! See related products below for our inexpensive and easy-to-install DIY kit.
