Have trouble filling tank without gas overflowing in FF Ford. I was gona check if vent is stopped up and apparently someone in the past has run the vent in filler neck to a T in return. Diagram in assembly manual doesn’t show which lines are which. What I assume was vent line goes to front of car near fuel pump and just ends to open atmosphere. It is stopped up probably why someone mad it T into return and that wouldn’t be a vent. Does anyone have a diagram or good photo of the top of tank labeling which lines are which. That line from top of filler neck should be vent. Why would it go all way to front of car. Any help appreciated.
Couple weeks ago I ask about fender height when reinstalling fenders and was worried about mine rubbing. Well I got fenders all back on and have drove car and they don’t rub. Sure looks like especially the left one would but all is OK.
I doubt the problem is the vent. The fill neck has a 90* angle right at the tank. You’ve got to nurse fuel in or the auto shutoff on the gas pump nozzle clicks off. There are some local stations I cannot use because it constantly shuts off. Also, make sure the clamps on the fill neck hose are tight.
The vent line that goes to the front was used for emissions on the donor car. If the carburetor was changed it was simply disconnected.

Looks like that huge hole going to the tank even making the 90* turn would carry the fuel. Mine actually pushes fuel up past the nozzle and out the filler neck unless I barely dribble it in, very aggravating. Do you have the vent in the filler neck and is it vented to atmosphere? If so I suppose I guess it is just something I’ll have to live with
