1972 to 1975 R107 350SL 450SL Complete Fuel Pump Conversion Kit

This conversion kit offers a replacement Bosch fuel pump with correct fuel pressure, new filter, all new hoses and clamps, extras as noted and full detailed video instructions by Kent

Since new original style pumps are no longer made, this is the best way to finally fix your old fuel pump leaks and poor performance. Weak fuel pressure can cause a variety of engine malfunctions. This kit is designed specifically for and ONLY works on the early 350SL and 450SL with electronic fuel injection (EFI) known as Bosch D-Jetronic. If you have a 1975 or early 1976 model SL and are not sure email us or get under the car and inspect before ordering. The same pump and filter with different inlet and outlet hoses will also work on the W108 and W109 small V8 sedans. You would need to order this kit separately. Please see the related products below. Watch the video as Kent will explain the reason for this kit and how it looks installed in a 300SEL 4.5.

Product Details

Kent explains what is involved to making the conversion

The kit contains the following:

  • New special sourced low-pressure Bosch Fuel Pump 
  • New fuel filter
  • All new fuel hoses
  • Required fuel hose adapter fittings
  • Special anti-kink fuel hose coil wire
  • All new fuel hose clamps
  • 4 new rubber mounts
  • Full video instructions

Kent's highly detailed video instructions will show you how to do this yourself. The new pump is not an exact match but will bolt into the bracket without modification and connects easily to the original inlet hose. What is different it the outlet to the fuel filter. Special fittings and copper sealing rings are provided to adapt the outlet side to the original fuel filter. A new Bosch fuel filter is included. The instructions you will receive are a collection of videos from other projects Kent has done and may or may not be filmed on an exact early R107. For instance, the procedure for draining the fuel tank and removing the tank outlet hose is filmed on a 380SL The draining procedure is the same even though you will be seeing a different style of fuel filter and hose connections to it. The bench assembly of the pump and filter are filmed from a 300SEL 4.5. Everything is almost identical but since the pump is mounted on the opposite side on the R107 you will be installing the pump and filter into the bracket going the opposite direction. Actual fuel hose replacement is filmed on a 1974 450SL.

This is what the replacement looks like installed in Kent's 300SEL 4.5. The R107 is mounted on the other side of the car and uses the identical fuel pump and filter. The mounting is reversed and the inlet and outlet hose arrangement is different as you can see below:
