Fuel leak

Ok now I have a fuel leak. 96 7.3. Just rebuilt the fuel bowl with all new "O" rings thinking that was it. It stoped leaking for awhile. I drove it everyday for 2 weeks after and no leaks. Now after it sitting for about 2 weeks (only driving it for a 1 or 2 days during that time) it starts leaking again in the valley of the motor and drips out the back on the motor. I need an idea on what to look at next. Thanks.

did you replace the hoses while you were in there?

Double check your fuel line connections, the ones you put on with the wrench.

Yeah I put all new rubber lines on and i can't see anything leaking from the hard lines. I'm thinking it may be the pump.?

When you rebuilt the fuel bowl, did you look at the bottom of the bowl for corrosion? could be that, or the fuel restriction sensor and, of course the fuel pump.

Yeah the bowl seemed to be in good shape. Its leaking more twards the back of the motor the valley behind the fuel pump and under the turbo pedestal is filling up with fuel.

Try first tightening the banjo bolt (1 1/4" wrench), if not, possibly the fuel pump, you can use a mirror to see the wheep hole under the fuel pump in passenger side.
