Hello all! This forum has been a wonderful resource for quite some time, so I felt it was time to come out of the woodwork finally and ask for some help. I have owned my 1982 300GD now for about 6 months and absolutely love it. She has some issues, the most concerning is losing fuel prime at inopportune times(after sitting for as little as 30mins) . It does have the new primer push style and not the older style. Unfortunately I have become well acquainted with this bulb. All the lines have been checked back to the tank and I have gone as far to add an inline diesel pump to push fuel up to the mechanical pump on command via switch, prior to ignition, this has helped considerably in "pump" time on the priming bulb when prime is lost. The braided lines have been replaced and double checked. Also, new fuel filter with new gasket. The vehicle starts brilliantly when prime is in good shape, first try. Idles beautifully. Shifts smooth and has all the power you might imagine a sub 100hp diesel might have. This leads me to believe that I am possibly getting air in the system somewhere near the high pressure injector pump. I would love to hear your thoughts on this, suggestions, things to check and double check. All help is appreciated, I have exhausted my reading on benz-world diesel threads. I enjoy this community and reading here, so this will be my first post. Thanks in advance for your time.
