Installing a new tank from Mancini(does not look at all like the original!) My main question is does the tank need any makeup air or does it get air from the vented gas cap?
Car is a 70 ebody cuda, only line I use is the fuel line. The existing /original sending has a small breather tube that is plugged at this time. The new tank has another little tube welded in the passenger side up high on the tank can I plug this line also?
Also this tank was ordered without ECU.
Thanks
