Hi everyone, I'm a little stumped on my truck and looking for some help. I have a 97 F350 with a 7.3 and the truck was running fine but some of the fuel lines around the fuel bowl was dry rotted and leaking. I pulled the fuel bowl and cleaned it up and replaced the o rings with the mil spec o ring kit from Riff Raff. I cant get the truck to start. The fuel bowl is full, I have fuel at the Schrader valve and I even loosened the high pressure hoses coming off of the regulator and ensured there is fuel there too. I have a reading on the tach while cranking. What can I check next? Is it possible I accidentally switched the high pressure hoses on reinstallation? Would it matter?
