I want to make a statement real quick that the vent line on the FCC NEEDS to be ran to a WORKING vent. and INTO THE TANK. THe vent is not OPTIONAL, and not to be ran to a charcoal canister. It 100% needs ran to the tank, and to be a vented system.
another replaced the tank vent line, with the FCC vent. this does NOT make it a vented system...you're pushing fumes into a completely sealed tank at that point unless by mere chance, it vents through the cap. which is NOT adequate.
thats my public service announcement for the day. :)
