96 E300 leaking air, bubbles in the lines
My 96 E300 is leaking air .when the engine is off I c large bubbles in the lines, n when it's running I c bubbles running in all the lines.
I have changed the the filter n pre-filter, with new O-rings. Yesterday I changed the Strainer n that strainer was dirty as hell!!! N the tank, when I pulled out the strainer I saw stuff like Black Mod was dripping out my tank so I just put my finger in there n pulled out alot of that stuff n I don't think I took out everything cause I only could put my finger in it. I'm planning to take my tank out n flush it when I get time. So after I change the strainer, it start up k n Bubbles still in the linesAhhh ! I really need help I can't think about anything else. My last chance is the fuel lines, I'm gonna change the fuel lines, but idk which ones, which lines I need to change??? Is it poosible that my tank is too dirty n cause this problem??? Help please

With that much air in your lines - are having trouble with the engine stumbling? Also, are you experiencing pressure build up in the fuel tank such that when you remove the cap to fill up you get a big wooosh of air coming out?

It seems like when my car sits for long time it will have hard time to start cause the air in the lines gets bigger.

N I never pay attention to that sound when I open the cap but I think I never heard it in my diesel. I'm gonna c it this time when I fill up.

If the car isn't shutting off as soon as you turn the key off, then you have a vacuum problem - and perhaps problems with other vacuum consumers on your car (door locks, brake booster, tranny shifts, etc). It makes sense that if your car sits longer you will get more air in your lines. If you have a leak somewhere, you typically get fuel coming out when the car is running and air being sucked in when it is not running. THe fuel will drain back into your tank and it will take longer to primer the pump and lines when you do try to start it. You'll need to clean everything up and determine what is leaking. Take pics if you want and post them here.

Thanks Lux. Yeah, it's worth pointing out that I am not familiar with anything newer than my '95 - so take it with a grain of salt. Others on here with your same model will respond. However I believe the fuel lines are very similar - as are the problems that develop.

If it's running/stumbling a bit before shutting off, then it's likely the o-ring behind the shut off valve. Are you getting a check engine light too?
You may just want to replace that 0-ring and then the other fuel line o-rings (or the plastic fuel lines... sometimes they leak between the black fittings & clear lines). Either way, someone is bound to post that you have to remove the intake manifold to change them... you don't. You just need to remove the fuel filter housing & windsheild washer bottle, and you'll have more than enough room to get at everything

Once you have access to the valve, it is easiest to pull it out with lines attached as a unit and work on it on the bench rather than hunched/reaching up under the IM replacing individual orings.
