How do you replace fuel filter on a 1994 Mercedes E320?

Answer 1

Hi, It is relatively easy to replace a fule filter on a later model E class Mercedes. I will give you the directions corresponding to the E class that I owned. What you need:Purchase the fuel filter and also two hose clamps that will accomodate hose width (screw-type), as you can not reuse the original clamps (these are factory-installed, crimp-type clamps meant for one use only). The fuel filter is an "in-line" part, so you will also need two lock clamps for the rubber fuel hose (so that fuel will not be allowed to leak out from the inlet or outlet hoses). Work: Make sure vehicle is chocked and parking brake is on. Apply lock clamps securely on either side of filter. Loosen crimp clamps using screw driver, but be careful not to gouge fuel line. Remove fuel filter (you will have to loosen the retainer clamp that holds the fuel filter in place). Capture fuel in a pan or RubberMaid-type basin. Caution, the fuel filter will have gas in it. Remove the crimp clamps and replace with new screw-type hose clamps. Install new fuel filter and tighten retainer clamp (make sure the arrow on the filter is facing correctly, the same way as the used filter). Push fuel hoses onto filter nipples all the way. Slide screw-type hose clamps toward fuel filter, over nipples and tighten well. Turn engine for a few seconds to allow fuel to enter the new filter. The engine will eventually start. Dispose of used materials in recycling bin, if required by law. Good luck!
