What is its purpose and do I need to add that or will the vents on the tank "box" suffice? Thanks! Your vent should be fine .Does it have a rollover check valve ?The vent to the filler is to allow the fuel to go in as fast as possible .If this vent is clogged or pinch it takes a long time to fill your tank.Here is a good link with pictures of a tank build .Yours is looking good and it's huge ! Why so BIG ? http://www.streetrodderweb.com/tech/0909sr_building_a_custom_gas_tank/index.html | | |
