Fuel Filter Change August 09, 2024, 04:16:52 pm Just changed out my fuel filter. I hadn't done this job on the LD before and I didn't see it in The Companion so here's the process for future reference. The filter is located in the frame rail more or less under the driver's seat. I removed a heat shield which kinda blocked the outlet side of the filter. Made it easier. You need a special tool to release the fuel line from the old filter. You can get one at any parts store. You just pop off the retaining clips and using the tool, release the in and out fuel lines, slide the new filter into its cradle, push the fuel lines onto the filter until you feel them catch and click the retaining clips into place. Just have to make sure the little arrow on the filter is pointing forward. I wanted to relieve the fuel pressure before I started so I disconnected the inertia switch which is located on the pax side behind the plastic trim. My plan was to disconnect it and then run the engine out of fuel. Best laid plans... The engine won't start with that switch disconnected. However, there wasn't any pressure when I pulled the fuel line off the old filter so I don't know if my great idea worked or not. Maybe there's never pressure at rest. Perhaps someone that is familiar with this job can comment. Anyhow, nice to have a new filter!jor 4 Likes

Re: Fuel Filter Change Reply #3 – August 10, 2024, 12:02:59 am The fuel filter needs to be changed every 30,000 miles.Our 2003’s V10, has a test port that can be used to relieve the pressure in the fuel line. If the engine has not been started for a day or two, there may be no pressure at all.For the uninitiated, the release tool needs to be pushed firmly into the two fuel line couplings, after removing the clips, to compress the springs and release the filter. Make sure the fuel line release tool is made for 3/8” lines.Larry
Re: Fuel Filter Change Reply #4 – August 10, 2024, 12:11:02 am Mine has a filter (more of a pre-filter) on the bottom of the pump in the tank, plus another much larger "metal can" fuel filter under the driver's seat area as pictured here. I've replaced both of them (the tank filter was replaced with the pump- big job!)... This thread would have been handy to have before I tackled it but luckily the main fuel filter under the driver's seat was pretty easy to do... compared to dropping the tank! Thanks for the write up!

It filters the bigger chunks, with the finer particles filtered by the replaceable canister shown in Jor’s write-up.Replacing the fuel pump in our 2003 at around 100,000 miles, I was surprised to see the fuel pump's filter wasn’t dirty and the bottom of the fuel tank was clean and rust-free. It’s not a job I want to repeat.Larry 1 Likes
