The fuel tank block-off plate installs on a 2-3/4 in. diameter fuel tank opening that uses a lock ring and gasket-style closure. On a 1971-1973 Mustang, it seals the opening when fuel system equipment is removed or relocated.
Replacing or adding a block-off plate helps properly close an unused fuel tank opening and supports a cleaner fuel system setup. For applications where a vapor vent opening is being blocked off, a vented fuel cap should be used to maintain proper venting.
