I have a 97 cummins 4x4 and started to notice a fuel leak up underneath the driver side door. Here in Ohio its freakin snowing constantly so Ive been unable to get up underneath it fully. Anyways,it leaks about a 5in in diameter puddle overnight. Has anyone had this issue in this spot before? Im getting mixed reviews on the internet about this!

 

Probably a fuel line going to the lift pump from the fuel tank?Has the truck ran different?Lope at idle?

 

There is a quick connect on the end of the flex line before it goes into the lift pump. There are some o-rings inside this connection that could be leaking. You may have to use a pick to fish them out, but there were 2 rubber o-rings and 2 plastic rings in mine i think. i took it apart there when it was gelled up to blow the line out and successfully blew out the o-rings.

After they came out i had to use a small socket to push them back in there.
