I recently was able to fire up my new ls3 in my 1966 nova. To start it I added 5 gallons of fuel to the tanks inc tank. It has a in tank pump and pickup. It also has a fuel vent off the top that I have connected above the tank height. Since I have added the fuel it smells like I have a bad fuel leak but there is none. I capped my new fuel vent just to check if that was it and it was not. My fuel lines are all -6an braided fuel line made for fuel. I am using a Holley regulator/filter next to the tank. Has anyone else had an issue like this? It smells like fuel if it’s running or not.
