Holley's HP™ In-Line Billet Fuel Pumps are designed to be the perfect companion to your carbureted or fuel injected race car, off-road truck or any engine needing fuel! The HP™ fuel pumps feature OEM gerotor technology which yields lightweight, quiet operation and 100,000+ mile durability in a cost effective, attractive package.

The 12-800 features improved hot fuel handling capabilities and was designed to greatly reduce the negative effects of heated fuel now common with many of today's pump gas blends. It is compatible for use with pump gas or race gas. If you are using E-85 or diesel, no need to worry, Holley has still got you covered with the 12-890 fuel pump. HP fuel pumps work well on the street or in racing applications with up to 18.5 volt charging systems and 80 psi
