I have an 03 F-250 with the 7.3L 307K on the odometer. I noticed a small puddle under the engine when I was at work. It doesn't look big but I want to get it corrected before it does and costs me a small fortune I don't have. I have been told by some that small leaks are common on high mileage trucks. Need some advice and tech tips guys, I'm All ears.

 

Need to get into the valley of the engine with a flashlight... It could be fuel bowl drain valve, could be any of the fuel lines around the motor... gotta investigate..

 

Saw some fuel around the fuel filter on top of the block. I had the engine running and didn't see if coming out anywhere. I'm still learning about diesel's so hopefully I find this before it gets bad.

 

It's up there... My guess is the drain valve on the fuel bowl... The yellow piece... pretty common place to spring a leak.

 

Is that a pretty easy fix? I'm still learning how to do some work on the engine myself.
