Well have around 400 miles on my new motor pulled it in garage today and noticed fuel puddle near left rear wheel--get under car and there is a white valve attached to the brake line bracket right near fuel pump plug-Is this a rollover check valve?? Any ideas would be great---tank is near empty and leaks when car is running---this just started like i said have 400+ miles on this setup and never noticed any puddle. Thanks

 

No, it is a vent for the tank. Are you sure the fuel is not from the EVAP canister? It is in the LR wheel well.

 

The canister i saw. How would the full get in there.. i did delete evap w new motor and was thinking to much pressure in take is forcing it out. Was going to try to drive w cap off and see what happens. a lot of pressure when i took cap off.

 

I think you answered your own question. You deleted the ability to purge fumes from the tank. They may have condensed and soaked the canister. Why delete they EVAP?

 

My old man needed the solenoid for his vette while my car was apart. and i never got another 1, actualy thought about that after i posted it. thanks for your help. ill keep everyone updated.
