69 fuel tank vent holes

6442 Views 6 Replies 6 Participants Last post by  von
I have a fuel tank on my 69 with a vented gas cap. When I fill the tank up, fuel pours out of the 2 vent holes on the top corner. Question I have is can I simply plug those 2 holes as I am using a vented cap? I have seen some say they use a 3/8' line attaching to a fuel filter and then run a 3/8" line up above the tank, I assume this is zip tied somewhere in the frame?

Any help would be much appreciated. Thanks.

I've addressed this issue in the past in regards to my car (a 20,000 mile original unrestored when I bought it 11 yrs ago). My car never had the small foam-filled just had (and still has) the two hoses going up to the bracket on the frame or underbody. So, the hose ends are just open to the atmosphere. I have never had any problem with fuel spilling out of the hose ends.
