I have a 2001 HD 2500. It has developed a massive fuel leak that is running down the rear center top of the block unto the bellhousing. I cannot see in this area as the firewall wraps around it. The truck has 185,000 miles and will start and run, but with a long crank time. No oil contamination and the topside fuel lines are dry. What lines ,connections etc are located there? I have been searching for pics so I see what I have to remove to gain site access in this area. Any comments would be appreciated.

a fuel leak as you describe would have to occur after the injection pump a line/fitting could have cracked a seal fail

x2 look behind the thermostat housing you souls see 2 fuel lines off the injection pump
