7.3 fuel leak

[MNTAIR]

Hey guys this is my first post...I just bought this truck from a friend who warned me that it has a fuel leak somewhere...? I searched the top of the engine with it running but could not find the source of the leak. The fuel drips out the bottom of the bell housing while it is running, when the engine is revved up, it comes out in a small stream .

Also, the first time I tried to drive it to work I started it up (about 20F outside and no block heater) it started great and I let it warm up about 20 minutes, when I went to leave, I just barely got out the driveway and it studdered and stalled, it restarted just fine but continued to do the same thing. I got it back to the house and there she sits . I assume this is related but am not sure yet. This is my first diesel.

Any insights or help woud be very much appreciated!

Check the water separator valve for the leak. If you are having to use the "new and improved" low sulfer diesel the o rings dont get the lube they need and leak. The rough running when cold I dont know about and mine is doing the same thus why I am here.

Marc, guess we were thinking the same thing. I had a 95 that was doing that and it was the o-ring on the fuel pump. Replaced the pump, no more problems.

It's a '95 with a '96 engine.

Could be the fuel pump. The pump sits down under the turbo pedestal. Could have a cracked o-ring. There is a drain hole at the back of the block, that's why you are seeing it coming out of the bell housing.

Is that the drain hole that you can see at the back on top of the block (in the "valley") of the engine?
Also, what service manual would you recommend for a powerstroke?

more than likely its the fuel pump or one of the lines to the fuel pump
