Fuel Leak

On my 97 F350 I noticed that there has been some fuel leaking from the drain in the bell housing. From looking on top of the engine I found that there was fuel in the valley. I believe that the source of the leak is coming from the fuel pump and I am assuming that this means that the fuel pump is going out. I am not sure what steps to take from here as I am new to the diesel world. Does anyone have any pointers of what I should do from here? Thanks for your help in advance.

Re: Fuel Leak

Can I determine this without taking out the fuel pump or does that have to come off?

Re: Fuel Leak

Just try the drain back valve orings. Roughly 40 bucks from your local Ford dealer.

Re: Fuel Leak

i use a good flashlight and one of those telescoping mirrors from the parts store to find fuel leaks. you can look at the fuel bowl and lines with the engine running and see where it drips. the rubber lines are prone to leaking after many miles and years, also the sensor that screws into the back of the fuel bowl might leak. i'd dry out the valley real good and pin point the leak before you start unbolting stuff. good luck!

Re: Fuel Leak

I have looked very closely with a flashlight and it apears that the drip is coming from the fuel pump rather than the fuel bowl.

Re: Fuel Leak

X2 with cleaning it up, using a mirror and a flashlight while the engine is running. To figure out where the leak is coming from.

Re: Fuel Leak

I rebuilt my fuel bowl with all new o-rings and it still leaked fuel. Turned out it was the fuel filter vacuum switch which is on the fuel bowl. Apparently its a common problem. Costs about 50 bucks at the dealership.
