2014 Caprice 6.0 fuel leak
Smelling fuel after filling up with e85. Found a puddle under the car on the passenger side near the front of the rear wheel. Went and drive it for a few days. Now no leak. Any ideas?

Seems to be leaking when full. Haven't smelt or seen anything once it got under 3/4 of a tank. Thinking maybe the hat is leaking. Anyone who has had this issue and can spare some advice, I'd really appreciate it

Check the inlet hose from the fill neck. You can at least see that without dropping the tank.

Today the tighten fuel cap flashed up on the screen and the cel came on. Gonna get it up a lift today and see what I can see.
Re: 2014 Caprice 6.0 fuel leak
I believe that the evaporative fuel system is looking for certain tank pressures depending on the fill level of the tank. Could the leak point be "venting" the system?

It was a crack in the fuel pump module. Replaced pump. All better now
Re: 2014 Caprice 6.0 fuel leak
Thanks for the update. Weird usually do not see issues with the plastic of the module so quickly.

Someone prior to me "worked" on it. Had hose clamps and deal on it. Real quality backyard work.......
