OM606- Sanity check fuel line air leaks
Alec and barrote,
The check valve in the supply line seems to have fixed the problem.
All the o-rings, crush washers and lines are new.
I had a thought last nite and I think this may be the problem. This is a conversion. I put the om606 engine in my truck which didn’t have a return line. I added one but I just added a fitting to the fuel tank pickup flange.. I didn’t extend the return line into the tank so the line is not submerged in fuel. I suspect the air was traveling thru the return line into the filter housing when the SOV is de energized and allowing the supply line to drain back into the tank. The check Valve prevents this and the truck started perfectly after sitting over night.
