Now, it does not intervene with the pump or the line coming from the sender side, and i can't see if it damaged the transfer pipe. Once fuel goes down I will check it out and report back here. The 1 cause of fuel pump failure is a clogged fuel filter. I have never found a recommended filter change interval listed. You should now be able to see a fuel line coming from the tank and then going through a cylindrical metal part, which is the filter. Parts guy: You know thoes do not need to be changed either. Hi everybody,does anybody know how to change a fuel filter on a 2002 E39 530D i have changed them on a petrol engined car where you pressurise the system by turning the ignition on and off a few times but have a feeling it's slightly different on a high pressure diesel system.
It has a saddlebag style tank, and I understand there is a pipe linking them together. That's why I think fsh ain't worth the paper it's written on! Most airfilters on petrol cars now have a massive interval. In my experience fuel filter rarely go bad themselves. The siphon jet comes with two new gas tank cover seals - you do not need to buy them separately. I pulled the old siphon jet out the tank, inspected it, blew it out with compressed air, etc. Today i will be removing the sender unit again to double check things. All seemed right with the world.
Peace of mind in having new components 160k miles at the time though, my particular problem was an internally corroded + wire to the fuel pump, just under the passenger side sending unit cover. The fuel filter on the 300E should be replaced every 20,000 to 30,000 miles depending on the conditions in which the car is driven. Sometimes the fuel filter can become clogged to the point where it negatively affects engine performance. It tends to be more notable when accelerating. If you fail to do this, when either side of the filter is disconnected, you will start to siphon fuel from the tank and end up with a huge puddle of gas. Afterwards, I did the same thing and they essentially reversed i.
Would be grateful if anyone has info. Could this be the problem? I agree 50k is about right Hia All. Regards, Jerry at 48k and counting. Also make sure you transfer the small plastic washer from the old filter to the new my new filter did not come with one. Manually move arm through range and follow resistance measurements.
I never searched for anything here. The Check Engine Light can be set off by a wide variety of issues, so having the computer is highly recommended. Values are in the Bentley manual. Any suggestions to how this suction jet actually works or how is is supposed to be installed would be great help. I took the pump out today and i noticed that where the pump clips into the plastic housing there is a crack on the bottom of it. This occurs as particles clog the filter and deplete the fuel supply going to the engine.
Just a generic warning that the system can hold up to 5bar of pressure careful that will put an eye out. Replace the fuel filter and watch the dirty fuel spill out of the inlet side. Always wondered where the filter was hidden. In actuality, the forward edge of the cover meets the bottom edge of the wheel well. Curious what the rest of the folks have been doing. Use something on the jaws so you don't nick the hoses.
The clogged fuel filter puts too much pressure on the fuel pump and prevents the proper amount of fuel in the fuel tank from reaching the engine. Then you realize that the cover is tucked underneath the rubber jacking point, Doh! I typically can get around 350-400 miles on a full tank of gas before having to refill when the gauge only read empty. I then started running out of gas when the driver side tank was still mostly full. How does one test if the filter is in need of replacement or do you simply wait untill it actually dies on you? When I went through diagnosing an intermittent no-start condition. It might mot be your problem but its a good start. The dealer lists the pressure regulator as a seperate part. Oh what a joy it is to take all these out! The only way to see if a filter is going bad is to run at full speed for a period of time and see if your engine starves for fuel, runs lean, then pops a piston or two.
Looked through some old threads but didn't see anything definitive. After reviewing my average driving condition since the last fill up, I've been mostly on city, stop and go traffic. Don't smoke when working on this. Brown sediment can poor out when you take it off. With the old filter drained it still had a significant weight advantage over the new one, indicating that it was pretty full of crap.
I think at 85,000 miles i'd like to change the diesel filter too. Thank you to the responses. You need to remove the left front jack pad and then the plastic panel that is behind the pad. I hope it didn't catch fire! Otherwise, 60k miles seems reasonable to me. Me: I don't believe in lifetime fluids. My car had fsh when I bought it with 150000 miles on the clock and the engine breather filter had never been changed! Its been remapped and goes like a train but im notg sure if im just getting used to it or if i feel its power is down just a tad. Engine Performance Problems Other symptoms of a bad fuel filter fall under the category of engine performance issues.
Parts guy: Ok heres the seals, anything else? I too replaced my fuel filter not too long ago, without any immediate need e. The position of the cover in the picture is a little to the rear of it's actual mounting position. If it is driven in dusty, dry conditions the fuel filter may need to be changed more often. From what I remember the clips on the hoses needed a special socket so I cut a groove in with a hacksaw and used a flat blade screwdriver. Careful there is a good quantity of fuel in the filter. So try that first if you don't have a new one in there allready it's cheap and known to cause problems with that.
