Hey guys I'm new here I've been following this forum for months since I bought my 96 E300 n i have some problems c if u guys can help me out , My first problem I had it was the k40, which cause the abs, ets, no cruise control, speedometer wouldn't work(got speeding ticked when I didn't know how fast I was going) n my engine would cut off sometimes. So I just searched n find out the k40 is the problem so I got a new k40 n I don't have that problem anymore.
The other problem I have is air leaking in lines, when the engine is off I c bubbles in the lines, n when engine is running I c bubbles running in the lines , so I changed the filter n O rings , pre-filter n O ring N I still c the bubbles in the lines,
Some times when I start the car it feels like it's gonna cut off.
Is that normal???
Do I need to changes all the lines???
Wuts the problem????
Somebody help please
Thanks guys n sorry my English is not perfect

might be the strainer in the tank is part clogged, or maybe leaking fuel line at tank? not real sure about your system w/ out seeing it, but deisel will grow algae in it. wtf??? tank may be full of algae if it sat for awhile before you bought it. that will clog the strainer. someone does make an algicide for deisel fuel. never used it, don't know much about it, just a wild guess. good luck.

Yep on the tank strainer as it might be clogged and as the IP is trying to suck all it can and if there a teeny leak it will get air.
Sometimes there is no need to change the clear line if they are OK, just the Orings, a lot cheaper to start with
Where are the bubbles starting? Do you see them on the first clear line going to the filter or only after the filter?

Replace the plastic fuel lines under the hood.

I checked almost all of those plastic fuel line n they like new, well ima change that strainer then if it didn't work I gotta change the fuel lines

The fuel lines are much easier to change than the strainer, so I would do them first.

strainer is more likely the problem. if the car sat especially. also, unless you know the po took good care of the car, there could be anything in the tank.

I beg to differ, Shovel. The plastic fuel lines on the 210 fail with regularity. If his are original and there is visible air, the problem is almost certainly the lines.
