our 85 300td was loosing power when climbing hills so i canged the fuel filters,which didnt help.so i checked the strainer in tank ,looked good.after checking strainer it ran alittle rough but smoothed out,then i tried driving it up a mountain and it quit and would not start.i had noticed some leaking from the stock bleed pump so i replaced it with a bosch hand pump,thought maybe it could be sucking in air?now i cant get a good bleed on system,i have even tried another pump.it doesnt seem to be drawing in fuel and when it does it looks frothy or bubbly.i have blown air through the feed and return lines,even replaced the rubber lines at tank.the clear filter is not filling up like i remember it has done in past (when priming).could there be something going on in the lift pump,i can pull the hose off the injector pump coming fron the hand pump and get some fuel movement but seems bubbly.i need to know how to check the fuel sytem from the strainer to the injactors. i am really getting frastrated!!!!!!!
