Gas Puddle when filling
#1

Seem when i fill my tank, i get a nice puddle of gas under tank. I only filled it a few times. Could this be the overflow i see on filler neck? Or is this the cause of the evap vacuum leak code that pops up? Intermittently. Thought was gas cap that was causing leak. But cap seems to be tight.

Guess my question is how can it be a sealed system that can detect slight evap pressure and have an open overflow hose. 
Thx

Looks like using other pumps this does not happen there is an overflow hose very close to top of filler neck for this purpose. Just dont overfill, which is easier said than done.

Ok, its not me at times the evap box just leaks bad! must look under there and see what's going on. I see a relay and some wiring. something is not working correctly. Any input appreciated!  Updated found a stainless line coming from rear that looks like it fell off or was never on from the EVAP purg solenoid valve in engine bay.  will update.
Found a hose off in the engine bay that goes back to the evap system. Problem solved
