DIY Installation Made Easy with Expert Guidance
Replacing your 72 Mercedes 450SL fuel pump might seem daunting, but with Kent’s detailed video instructions, it becomes a manageable task. While the new pump isn’t an exact replica, it’s designed to bolt directly into the original bracket without any modifications. The kit includes special fittings and copper sealing rings to adapt the outlet side to your original fuel filter, ensuring compatibility and proper function. A new Bosch fuel filter is also included in the kit.
The video instructions are compiled from Kent’s extensive experience working on Mercedes-Benz R107 models, including procedures filmed on a 380SL (for fuel tank draining) and a 300SEL 4.5 (for bench assembly). While the videos might show slightly different models, the core procedures are directly applicable to your 1972 450SL. Specifically, fuel hose replacement is demonstrated on a 1974 450SL, offering a visually relevant guide for your project. Remember that due to the R107’s pump mounting location, you’ll be installing the pump and filter in the opposite direction shown in some video segments.
Customer Success Speaks Volumes
Our customers rave about the ease of installation and perfect fit of this fuel pump assembly. Here’s what Rob from Seattle had to say:
Holy cow, Kaia. This updated fuel pump assembly fit great and was way easier for our tech to install than anticipated! We still need to do some testing but the fitment is perfect. Please thank your dad for us for making a great product!
Critical Fuel Pressure for D-Jetronic Systems
Kent emphasizes the importance of fuel pressure in the D-Jetronic fuel injection system used in the 72 Mercedes 450SL. This system is highly sensitive to pressure variations, with the factory manual recommending only a 1 psi tolerance. Replacing your fuel pump and filter can alter the fuel pressure, often leading to an increase, which can result in a richer fuel mixture and increased fuel consumption.
Therefore, after installing your new fuel pump kit, it’s highly recommended to test and adjust your fuel pressure using an accurate gauge. Many older 450SL models may have had their fuel pressure adjusted to compensate for a failing original pump or a faulty fuel pressure regulator. Ensure optimal performance and fuel efficiency for your 72 Mercedes 450SL by verifying and adjusting the fuel pressure after pump replacement. For those needing a reliable fuel pressure testing setup, Kent offers a tested and ready-to-use kit, available separately. Upgrade your 72 Mercedes 450SL fuel system today and rediscover the joy of driving your classic Mercedes-Benz!
