Need Fuel Line Diagram for 86 F250 w/6.9 Diesel...
...
I'm looking at buying a 86 F250 w/6.9 Diesel. I have had the chance to see it yet, but the owner says there is a fuel leak that is originating behind the engine towards the top (near the firewall).
He says it's not leaking near the fuel filter or anywhere underneath the truck.
He's describing it has a steady drip.
Where could this leak be coming from ??
