2002 Duramax fuel leak

My 02 Duramax at 80,000 miles started leaking fuel under the motor, anybody have that prolobem. Looks like it's going in the shop.

Check your fuel rail on that side and injector connections. My driver side fuel rail leaked about 4 years ago. Had to have it replaced.

The leak not around the fuel filter. The leak is underneath, coming out of a 3/8 plastic hole on the right side.

Where exactly is it leaking from? I know that if you haven't done it already, the fuel filter head seals wear out and it will start leaking from there. The fuel filter is located on the passenger side, just under the intake tube. If you have fuel in that area, it is most likely that leaking. I have already done this repair on 3 Duramax's. 2 LLY's (04.5 - 05) and 1 LBZ (06 - 07) trucks. Only 2 of them had problems with losing prime, where you would have to pump it up to the filter head again to get the truck started.
