I had a leak filling the valley of the engine. When I opened and inspected I noticed the banjo bolt area leaking on back of the fuel pump. I tightened and the dripping stopped. When I took it for a drive and checked again there was diesel in the valley. So I decided to replace the washers for the banjo bolt on the back of the fuel pump and still leaks. Next I bought all new hoses from Ford, pulled the fuel bowl, installed new hoses, installed bowl and now, immediately after install, it idles rough with less power on the road and sputters as I accelerate. A few weeks ago we replaced cups and it ran like a new truck until tonight after I installed the bowl. Somethings caddywampus! Also ... still have the leak after a 10 minute test drive. Any suggestions?
