Newton Replacement Fuel Cap

These fuel caps will fit all SPRL Flanges, e.g., the SPRL Universal Flange and G/S Flange.
SPRL flanges are the stock equipment on newer RV kits, so this little upgrade can be used in any new-built RV. 

Sold as individual units (order two if you need to replace both fuel tank caps). 

Locking units ordered together will be keyed-alike.
