W124 E300D 1994 - Power Loss Uphill/50mph+

[Boot]

Hello.

I bought a 1994 E300D (OM606.910) a few weeks ago and have been driving it trouble free, until one day on the motorway (70 mph) the revs dropped and I started slowing down. I pulled over and the engine spluttered to a stop as if running out of fuel, despite having half a tank left. I started it up again after a few cranks and drove home slowly.

This happens time and time again, quite predictably, when going uphill or overtaking.

So far I've checked the tank strainer (not there) fuel filter and cleaned the fuel pre-filter, all to no avail.

Has anyone has any experience with this problem? Any advice would be greatly appreciated.

Kind regards

Bad fuel system O rings.
On the fuel shut off valve and/or the fuel pipes. Very common.

Can you see air bubbles in the fuel pipes? If they're old, they go darker and more opaque making visibility poor.

I've just cleaned all the schmutz off the clear pipes and there are indeed lots of bubbles in the pipes by the fuel filter. I'll look into changing those o-rings. Thanks.

Change the fuel filters. Hope this helps

Yes, fuel filters as well (inc. cleaning out the little 'witches hat one in the housing).
I'd do the pipes first if there's evidence the main filter has been changed (50K-ish interval).

Are you on diesel or veg?

Unhappy Help changing a W124 Fuel filter
Hi guys i have a bit of a situation on my hands and need some advice clearing it up! So here goes!!!

I have a 1992 W124 and in dire need of the fuel filter changing i have a new filter and just went to fit it however i have undone the banjo on the front of the filter that was straight forward enough but when i move round to the back of the filter onto the the compression fitting the fitting seems to stay with the fuel line!!!!! is this how it is supposed to be? and if so i have got the wrong filter? or should the compression fitting have stayed with the filter?

any help would be great guys

Kindest regards

Angus,

You'll get a better response if you start a new thread with your issue.

Just got pinged, I thought I would thank you all for your help. In the end it was a vacuum build up in the fuel tank thanks to a clogged breather pipe - it ran perfectly with the fuel cap removed, I'll have to see about replacing/cleaning that pipe.
