Project Iona Part 5: 1997 Mercedes S500 Fuel Hose, Fuel Pump, and Fuel Filter Replacement

Welcome back to W140 Restorations and Part 5 of Project Iona as we replace the entire fuel assembly under this S500. Watch as the original main fuel hose from the gas tank gets replaced with a new set of crowfeet wrenches and original Mercedes-Benz replacement parts. We trade out an off-brand fuel pump for an OEM replacement one paired with a new Bosch fuel filter and fuel lines. Watch as we test the fuel pressure at the rail and cross our fingers to see if it stays within spec.
