I picked up an '86 300E locally for $1500, one owner, nice MB. Replaced the OVP due to it turning over but not continuing to run; has worked fine but at least twice since replacing the OVP it takes at least three tries before it starts and keeps running; I am thinking it is not maintaining fuel pressure, check valve and filter replaced in '06; the only other odd thing was the fuel gauge going crazy back and forth, I would not think that had any bearing. Any thoughts would be appreciated.

on another note, speaking of bearings; the fan motor was seized; took it out, notched the bearing and housing lip around it, held it tight and were able to work the shaft free; a lot of patience and lubricant got it done.
