Hi all,new to here. my 94 300D om 606 engine stall in these cases:
1, start at once in the first crank of the day,cool engine.
2, difficult to re-crank again after heated of engine unless apply gas pedal to help.
3, when in the traffic congestion,with air con in,stall engine after apply gas pedal for car move forward.
4,discover o ring leak in primary filter out side,and o ring leak in the higher pressure side after lift pump near secondary filter.

I suspect gas go in from the fuel hose of lower pressure side o ring after primary filter,and combine into gas/fuel mixture that go into the injector,then stall engine.this may be caused by difficult to suck fuel of clogged fuel tank filter?

Any suggestion? thanks!

welcome to the forum, I'm guessing you are using a translator to present your information?

everyone who responds should type simple sentences to ease understanding.

yes, a leaking fuel line will allow air into the system, resulting in difficulty running.

your car should be similar if not identical to the USA 95 E300, so those familiar with that model should chime in soon with help.

Welcome aboard.

Replace o-rings,hoses in area of injection pump and fuel filter to get rid of leaks first. Remove shut off valve and replace the o-ring on it too.

Prime system after replacement.
