Is anyone able to identify a fuel leak? I have video and cannot get it to upload from work. Fuel pump just replaced. When vehicle is running there is a bad fuel leak coming from tank area, appears to be coming from the left side of tank (as you face from the rear). I got directly under to tey to get video but it was too dark to see anything on the video.

I'd like a bit of feedback please before I take it somewhere for repair. Mechanic who replaced the pump thinks a rodent may have chewed through the return line. he has not been back out to diagnose.

Thank you, as always, for your feedback!!!

 

Here's a diagram of the tank, nothing goes in on that side of the tank besides the tank vent line and the breathers, so its hard to say

 

If it leaks only when the truck is running, got to be the supply line, no? I don't think there is a return line. Pull the cover in the cargo area and see if there is anything obvious.
