OM606- Sanity check fuel line air leaks
OM606- Sanity check fuel line air leaks
I've cracked the injector lines on many a diesel... I'm, very familiar with the bleeding process. My issue is that once the supply line from the tank empties, even after filling the primary filter full of fuel, the lift pump will suck the line air back into the filter and then introduce more air into the IP. I've been trying to fill the filter and all the lines prior to bleeding to avoid that.
I suppose that's also true on the 606 system while the SOV is energized (suction vs pressure side) HOWEVER... I think once the SOV is de-energized, the pre and primary filters connect (through the SOV - see my post above about which SOV ports flow- energized vs de-energized). When the SOV de-energizes, almost all the clear lines including the pump outlet (pressure) line, are on an obstructed circuit with the return line IF that passage exists in the filter housing. It is then that the air creeps into my system. The only clear line that appears isolated with the SOV off is the pumps suction line which I presume is tied to the IP pressure galley through the SOV.
