Earl's Performance Dominator in-line billet fuel pumps are for those of you who are in need of a fuel pump that can support serious horsepower. Have a nitrous system, turbo or supercharger? No problem! These fuel pumps feature a twin-pump design that allows you to use one pump for cruising and both pumps when you activate your nitrous switch or start building boost. The second pump allows you to eliminate the unnecessary recirculating and heating of fuel that can lead to poor performance and hot fuel issues. Earl's Performance Dominator in-line billet fuel pumps also have an added benefit for hard core enthusiasts that run events like the Hot Rod Power Tour or the Baja 1000; that extra pump brings you peace of mind that you'll always finish what you've started. Features include: * Billet aluminum construction for durability and good looks * -10 AN O-ring inlet/outlet for high flow and superior sealing * Suitable for use with carbureted or EFI applications * May be fully submerged in-tank for custom applications, space savings, and reduced plumbing * Compatible with 12 V to 18.5 V systems at pressures up to 80 psi for street or race use * For hardcore race use, both pumps can be wired for full-time duty * Only 7.66 in. long x 5 in. wide x 2.5 in. tall for easy installation on frame rails or other tight areas * Patent pending dual-pump technology * Proven durability beyond 3,000 hours * Weighs only 5.1 lbs.--half a pound less than competitive 1000+ hp pumps * Not for use on aircraft of any type Note: These pumps are not designed to use standard conical seat-style unions in the inlets or outlets of the pumps. Use of this style fitting will block flow and WILL lead to poor performance and pump failure. The ONLY correct fitting to use is a contoured port fitting with an O-ring seal such as part # EAR-AT985010ERL.
