need help fuel leak
My 97' F-250 7.3 Diesel appears to be leaking fuel out of a weep hole at the bottom of the bell housing.
An unusal place for fuel to be leaking.
It is most noticeable when sitting still ideling and the drip is rather steady almost a stream.
Any one who has encountered this or knows any info regarding this problem would sure be welcomed.
Thanks in advance.

Climb up top & see if the valley under the fuel filter housing is full of fuel. If so, start looking for the source of your leak. Most likely going to be the fuel pump leaking from the weep hole.

Better give it a good inspection.
Most of the leaks found there originate in the valley, on top of the engine. the design routes any accumulated liquids in the valley to the rear and then out to the passenger side of the block, at the rear. Gravity usually pulls the fuel down to the bottom of the bell housing.
Normal leak culprits that fill the valley include the lift pump and the fuel bowl assemblies.

It is coming from the top of your engine. There is a drain hole in the back of the valley that runs into the transmission bell housing so any oil or fuel leak on the top will run out of the tranny inspection cover.
You could have a fuel leak from the fuel canister drain valve, any of the fittings on the fuel bowl, the restriction sensor on the bowl, any of the hoses between the fuel pump and the valley, banjo bolt or even a leak from the fuel pump itself. It will require some cleanup and inspection to locate the exact source.
Let me know if I can be of assistance.

I would like to thank all that responded, as soon as the truck gets back I will crawl under the hood and look.
As far as I know it is not a california model, it does have a turbo.
Should it be the fuel pump is this a costly repair?

If it is a Cali model there will be a sticker on the right (passenger) valve cover stating something about California. Also, you will see a black "disc" sticking out from under the turbo before the pump. Maybe 3.5"? around. It will be a costly repair if you bring it somewhere. It will be cheap if you do it yourself.

The fuel pump can be purchased as most local auto parts stores and I believe it is around $100-$110 range. Someone that has bought one recently will chime in with current costs.

Cali model fuel pumps are harder to change I have heard. I just changed my fuel pump and it is not that difficult, but, there is risk in dropping the pump pushrod into the motor. Mine did fall into the motor but luckily I was able to retrieve with a magnet
There are three hoses from the filter canister to the pump that can be cracked and leaking. There are several O rings in the fuel canister that can be leaking. The canister itself may have pin holes in the bottom from sludge build up that can be repaired with JB Weld. The FPR on the side of the fuel canister could be leaking. It has O rings as well. Pumps are about $100 bucks. I bought a Carter fuel pump of Amazon for $85

If this is true then, if Ford has it for $180 and "Track Auto" has it for $80 the only difference is 100 bux! I THINK

same leak
I ran into the same (sorta) leak with my '96. Electrolysis had eaten holes in the bottom of the fuel filter cannister. Remove enough stuff that you can feel the bottom of the cannister. If it feels really rough or you can feel holes, that's it. I got mine from Rockauto.com . $261 includes shipping and the new filter came with it. Perfect fit and took about an hour to put it on.
