Holley Aluminum Fill Cap Kit w/Steel Weld Bung

Looking for an alternative to your stock fuel cell cap or maybe you need a fill cap for that custom oil tank or valve cover you are building? Well, look no further! Holley has created a full line of Billet Fuel Cell Caps and Billet Fill Caps. Holley caps are CNC machined from 6061-T6 billet aluminum and they feature a bright black anodize for great looks and corrosion protection. Each cap features a laser etched Holley Equipped logo so you know it is quality product. Holley Billet Fill Cap kits allow you to put a fill cap or inspection plug anywhere it is needed. Kit #166019ERL utilizes a steel weld bung. All kits feature an easy to grip screw on cap with O-ring seal and a 1.38_x009d_ diameter opening.

Holley has been the undisputed leader in fuel systems for over 100 years. Holley carburetors powered every NASCAR Cup team and nearly every NHRA Pro-Stock champion for four decades. Now, Holley EFI products power these cars and are dominating the performance world. Holley products for GM's popular LS engine are dominating the LS scene as well. Holley's products also include performance fuel pumps, intake manifolds and engine dress-up products for street performance, race and marine applications. As a single solution or partnered with products from other Holley companies we can give you the edge you need over the competition!
