why does the primer pump act like it is under vaccum? i have tried to prime the i.p. pump up but, when i pull the primer plunger up it is very hard to pull and will "snap" out of my hand if i let it go. then the fuel in the filter "boils" with air bubbles. anyone else have this happen? 1980 300d .. been sitting for years. car starts but dies.
Did my wagon have a tank strainer on the fuel tank outlet when it left the factory? It doesn't appear to have one now and from what I've found doesn't look like the pictures in the manuals I've seen. I'm going to clean the tank and was curious. There appears to be drain plug midway in the tank. Is that really what it is?
Thanks.

I'm trying to get a 300 d started that has been in storage in a garage for 10 years. It will crank but will not hit. I have replaced both fuel filters and primed it to the injectors. Still not starting. Any ideas?
1979 300D. Stored for 4 years won't start without the block heater when it is below 60 degrees. The oil was not changed during storage. Glow plugs appear to cycle. Does anybody have any ideas? I am looking at purchasing this car but want to avoid a big engine problem.
Thanks!

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.
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?
Hello,
My Monovalve, the one that is bolted to the firewall and allows coolant into the heater core, has been stuck wide open, I removed it and it seems to be able to move now that I have cleaned it up a bit, is this item repairable, or should I just buy a new one....
Thanks
