I found my fuel leak. It is off the back of the pump (behind fuel filter housing) at the y where the lines are coming out of the pump. Is this something I can do? I am mechanically inclined, if all I have to do is take out the nut out the back of the pump and put new o-ring in. Is it that simple or what am I looking at? Also I found I am leaking coolant out of the temp sensor. I will get a new one of those and put in(hopefully not a big deal).....

 

If it's leaking from the banjo bolt on the rear of the fuel pump you will need two "Fuel Line Banjo Outlet Seals" (Ford) F4TZ-9A375-A. It's not too hard just a PITA.

 

Just make sure your coolant leak is the sensor and not the thermostat neck. Those are prone to leaking. I had to replace mine. Even the new one would not seal, I had to tap it lightly on the floor of the garage to get it flat enough that the rubber o-ring would seal properly. Instead of replacing the sensor put an actual gauge on your truck. Just a thought.
