Tank vents

I have a 70 442 /455 When driving the pressure in tank builds up so that the tank itself expands and when I take off the cap the pressure release seems excessive! I crawl under and see there are 2. hoses that are capped off ?? I assume they are the vent hoses and being blocked causes my issues?? Can I install a tank vent valve like sold by OPG to solve the issue ?? I tried a vented cap but it did not solve the issue ??Pl Help THX

This attaches to the two vents and mounts above the gas tank to a clamp to keep fuel from leaking when full.
