I have a 2003 F250 6.0 it started to be hard starting in the mornings, I have to crank it 3-4 times before it will start. After it starts it's usually ok starting the rest of the day. It also now has a fuel leak seem to be on passenger side rear of motor. I changed the fuel filters and batteries tested good. Any suggestions appreciated!

 

Fix the fuel leak and make sure you get any air out of the fuel system...see what happens after
