Re: [MBZ] 83 300D fuel starvation
If that is the turbo check the vac hose from the back of the intake manifold to the ALDA, clean it out at the manifold fitting and/or make sure it is airtight and hooked up correctly. That provides the overboost signal, if it is clogged it won't allow enough fuel or boost or something, leading to that symptom. It might also be suffering from the counter-rotation of swirl caused by being on the other side of the planet. A properly polarized magnetic turbolizer on the intake manifold and fuel lines would probably cure that.

Re: [MBZ] 83 300D fuel starvation
I cannot say this emphatically but I can from my own experience. An 84 300D Replaced all of the fuel lines, fuel filters, injectors, fuel cap seal. So, why am I still getting air in this fuel system? The cause of my running maybe twenty miles one day and perhaps five on another? The O Ring on the secondary fuel filter bolt. Replaced that O Ring and have driven probably four thousand miles since without a single out of fuel challenge Hope that heps. Dave H...

Re: [MBZ] 83 300D fuel starvation
I'd try the oring on the fuel filter first, then try replacing every hose on the suction side from the tank to the transfer pump, and the transfer pump to the filter. If the line from the filter to the IP was not replaced, replace that also, along with all 4 aluminum rings. My guess is the line from the transfer pump to the filter. If these are 124 300D's then there are the fuel heater lines also.

Re: [MBZ] 83 300D fuel starvation
Well the first thing I would do is clean out the ALDA line from the intake to the ALDA on the IP. If that didnt work, sounds like the turbo is dumping the boost. Dont forget to also check the switch on the firewall that is in the line between the intake and the ALDA, could be plugged or not working. Bypass it for a test.
