A/C problem with my 1984 300DT

On rare occasions when I turn the A/C on and select high fan speed the blower is very fast (read powerful) and the temperature is very cold......Great! On other occasions in fact most of the time when the A/C temp is selected and the high speed fan switch is selected the fan is slow and the temperature is warm to cool. Yet at other times if I switch off the engine before switching off the A/C for example when refueling and then turn the engine back on the fan blows H-O-T.

fuel leak related to power loss?

I have been experiencing an occassional power loss for quite some time now. A while back i took care of this problem when i found a loose clamp on the hose going to the hand primer pump. After tightening it and bleeding the system it took care of the problem.
Now i have a small fluid leak that i believe is coming from the bottom of the clear sediment bowl on my FM100. It is too difficult to tighten in its current position, so i have been putting off removing the FM100 filter.
Anyway, my question is this, can a small fuel leak like that be responsible for power loss?

Which Sourcelet or Guide Best for '80 300SD 116 Vacuum Troubles

The vehicle is a 1980 300SD, 116 Chassis with nearing 300K miles. My problems began with a slight delay in the engine shutting off with the key, and has progressed to no door locks and I have to raise the hood and manually shut the engine off. I have also noticed the engine is running rough at idle, but smooths out at about 1000RPM. I intend to troubleshoot the vacuum system, but can't tell from the descriptions which of the guides I should purchase: the vacuum door lock one, the my engine doesn't shut off one, or the larger, apparently more comprehensive diesel survivor's guide.

1985 300sd 30 mph max no power

I just purchased this car. It starts quickly and idles smoothly but has no power and will only go about 30 on flat ground. I removed exhaust pipe with the cat and muffler, thinking the cat was plugged, didnt help. the previous owner said the turbo got hot and caught the underhood insulation on fire but he got it out quickly and with the exception of 2 vacumn lines it didnt hurt anything. turbo area emits a highpressure air sound, not a turbo whistle,at idle and it gets louder under power. Any suggestions? Thanks Tom Postscript 1st benz Ive owned so have to catch up.

85 300D Wont start

I forgot to fill up the new fuel filter with diesel before installing. I realized my mistake after cranking the engine a few times with no engine start. I took the filter off and filled it up with diesel fuel and reinstalled. I still cannot get the car started, if the car does fire it only runs for a second or two then dies.

My car was running fine just before the filter change. I have not refueled recently. I have a WVO kit installed but have been running on diesel for the past week due to lack of WVO.

Is there a way to check for air in the fuel line?
