Diesel fuel bell housing

[iowaowb]

put the truck in the garage and diesel fuel is running out of the bell housing. Any thoughts? Thanks

Maybe a fuel leak from the fuel bowl in the valley. Any oil or fuel in the valley drains to the back of the engine and down.

fuel bowl is dry

Look in the valley for any puddles, if there is anything leaking up top it will drain out the back of the valley through a hole and come out from between the bell housing and the block under the truck.

If nothing there, check the fuel rail plugs in the back of both heads.

May also be leaking from the fuel lines at the back of the heads on top.

I respect any thoughts on this problem it is running ok not as peppy as it should be but it has 231000 miles too.

I have crawled all over the top of motor and cannot find fresh fuel and the leak has stopped for now?? Strange. When it first showed up it ran outside for 10 min. then moved it inside and it seemed to pour out. Since then I run to town and back (20min round trip) park inside does not leak a drop. Any ideas??

The rubber orings on something are getting flaky. I would probably just start at the back and work your way forward changing orings. Especially suspect is the fuel line that goes to the driver's side cylinder head in the rear.

I have had this problem before. When the orings are cold they leak, but stop when they get warm. It will get worse till you fix it.

A good cheap place to get the orings is Replacement O-rings for Diesel Engines
