Show original supplier description
The MagnaFuel ProTuner 525 fuel pump is an external, in-line electric pump ideal for street muscle cars and high-horsepower fuel-injected engines. It boasts a compact design, CNC-machined aircraft aluminum body, and a durable hard-anodized finish. Key features include quiet operation, self-priming, continuous duty, and no pump shaft seals to prevent leaks. This pump utilizes a high-torque custom motor that is more efficient than other motors, drawing very low current and never requiring a step-down. It includes double support bearings and can be rebuilt to its original condition. With 8AN inlet and outlet sizes, it can achieve a maximum pump pressure of 120 PSI and supports up to 1000 HP, drawing 10 amps at 45 psi. The ProTuner 525 offers flexibility with its included mounting bracket, allowing for vertical or horizontal mounting. Polymer wear plates contribute to its smooth and quieter operation compared to competitive pumps.
