i noticed a smell like diesel fuel, i looked under the hood didnt see much untill i got underneath saw wet on the suspension parts. any Ideas what could be leaking towards the front of the motor looked alittle wet on the side of the upper filter housing looked like some sort of regulator mounted on the side but not sure.

Have you changed the upper fuel filter or had any work done in that area recently?

The fuel pressure regulator is mounted to the filter housing. The seals have been known to go flat and cause a leak. I find it is becoming more common lately.

Check the secondary fuel filter cap. It could be loose.

i changed upper fuel filter about 10k ago i think alexb could be right the screws that hold the regulator on looked a little wet i will check tomorrow see if that stops it.

Thanks for the help , Tony
