Exclamation fuel leak

ok so ive noticed a small wet spot were the truck has been parked for all day every now and again but tonight at work i pulled the truck next to the building and it was almost leaking as much or more than it could be burning i didnt know what it was so i put a container under it and its diesel i drove it home and looked again and it wasnt leaking at all. when it was though it appered to be comin down and dripping off the starter where is it leaking from?

it's probably pooling in the valley and leaking down the back of the motor. I would keep it running and see if its leaking from the fuel bowl, if it is its probably bad orings on the drain valve or somewhere else on there. I bought a oring kit on ebay and replaced all my orings and my fuel lines on the fuel bowl. or your fuel pump could of gone south on you. after I did all that on my pickup, now MY fuel pump is leaking

its either the o rings or hoses on the fuel filter housing or the fuel pump is going bad, get a small mirror and a flash light and look in there, the fuel pump right under the turbo in front

buy a new lift pump.. they're not expensive but they're not very fun to replace. at napa they are like 104 I think. you can find writeups on here how to replace it real easy. or if you need I or someone else can find you a writeup. U have to pull the fuel bowl anyways to replace the lift pump, and if it was me I would buy a oring kit and replace them... because if they havent gone out yet, they probably will

1 1/4" wrench for the head on the back of the pump. I squeaked in there without pulling
the turbo. REAL PITA. Buy the new orings and replace them at the same time. This not something you want to do twice.

If you have the time and $$$, pull the turbo and do some preventative maintenance.
