OM606- Sanity check fuel line air leaks
OM606- Sanity check fuel line air leaks
(12-02-2018, 10:48 PM)AlanMcR I have two OM606's, factory installed. I had to eliminate the pre-filter on both due to leaks that could not be fixed. Even with new parts the air would leak in. Either the bore diameter is oversized or the casting is porous. Don't care, gave up trying. The problem was worse on the Gwagen, probably due to the bigger drop down to the fuel tank.
Use the hose ends at the the fuel heater and SOV, and make your own hose that connects them directly. Problem solved, permanently. The pre-filter is way too small anyway. Better to install your own that is bigger and closer to the tank.
If you still have your old parts they are perfect for this.
