Manufactured by Essex Industries, one of the most renowned fuel system manufacturers, these state-of-the-art Electric Fuel Pumps offer maximum performance in a compact package. With anodised aluminium housings and high-quality internals, they are both strong and durable. Each pump is factory-tested and includes mounting brackets. The carbon fibre vanes and composite rotors give these pumps the added boost for maximum performance. The high quality construction results in a pump that is 4 to 14 dB quieter than competitors pumps at the same pressure. # ED1791 is factory pre-set to 6.5 psi and no regulator is required. With a replaceable screen type inlet filter and the free flow rate of 120 GPH is sufficient to supply 600 hp. #ED1792 has a free flow rate of 160 GPH, enough to feed a 1000 hp engine. This pump is factory pre-set to 12 psi and requires an external regulator such as the new Edelbrock regulator # ED1727. Warranty will be voided when used with diesel fuel.
