Vented Gas Cap - Stainless Steel, 2.80 inch OD, 66-70 Ford Bronco SKU: 9748

Early Bronco Short Reach Fuel Cap | 1966-70 Ford Bronco

Ensure a proper fit and secure seal with this 2.80" O.D. Vented Gas Cap, designed specifically for early 1966-70 Ford Broncos. Unlike later models, this cap features a shorter reach to fit the earlier-style fuel filler necks. If your Bronco’s fuel system has been modified or rebuilt with parts from different years, double-check your existing cap to confirm fitment.

• Short Reach Design – Ensures a secure fit in 66-70 type fuel filler necks

• Vented Cap – Allows proper airflow and prevents fuel system pressure buildup

• Check Before Ordering – Many Broncos have mixed-year parts, so verify fitment with your vehicle

• Aftermarket Filler Neck Compatibility – Be aware that most aftermarket early Bronco filler necks use a long reach cap, see #9747 to purchase.
