Angry Fuel Leak at crossmember

I know there's a lot of these questions on here but after searching have found nothing similar to my problem.

Truck:1995 Ford F-250 4X4 with 5spd. 138,247 miles

Problem: Just replaced the fuel pump, completely rebuilt fuel bowl, and all hoses. The intake valley was cleaned before re installation and has no fuel leaking or sitting in it even after a long test drive. I have a small and slow drip of diesel fuel coming off the back of the cross member and cannot see where it is coming from. It frustrates me because after all this hard work I did, I still have a leak. Any suggestions. Thanks, Jimmy

If the leak was from the top end then it would be coming down the back of the block and would show at the trans bell housing area. If you're having fuel at the cross member I'd be looking at the fuel drain switch on the bowl. The dump tube goes down the front of the motor and stops about where the cross member is.

I agree. Recheck everything you have done.. I installed a new fuel pump and the small brass washer would not reseal so I had a small leak until I replaced.. And the last time was the drain valve..
