In looking at the posts on installing a mustang tank, everyone seems to add a vent. Is the original installation in a Mustang vented through the cap? I am planning to install under the bed in the F-5, and the filler in a small metal box with a flip lid on the bed. This is a working truck, so I don't really want/need anything as pretty as the flush mount fillers, so using a stock Mustang cap, do I need to install the rollover vent?
Thanks again for the great posts.

Yep! (I think)

Not as long as you have no intention of rolling over and the other reason for the vent was for ease when fuel filling, …………venting the trapped air.

 

Stock Mustang caps were vented. They were also large and fancy, since they were exposed on the rear body panel of the car. You can get a standard, generic type replacement that's vented and it should work just fine for you.

 

I got a rollover vent kit from Midfifty and connected it to my filler neck vent hose, then have a sealing gas cap.

I have a remote rollover vent already as I was originally going to do what you have done.Where did you mount the vent and how did you connect to the filler neck tube.
Do you have any pics.
