Airtex Fuel Pump Mechanical

Fuel Pump Mechanical; OE Replacement

MPN: 531

Mechanical fuel pumps were the standard in vehicles with carburetted engines. However, when fuel injection became common and higher fuel pressures were required, electrical fuel pumps became the norm. Some still prefer mechanical fuel pumps because of their ease of installation. They don’t require extra wiring, so there is no risk of electrical issues, and they are extremely reliable. Mechanical pumps are also quiet and shut off when the engine shuts off. Airtex Fuel Delivery Systems is the only U.S. manufacturer of mechanical fuel pumps. Our mechanical fuel pumps are designed to meet or exceed OEM specifications for fit and performance. The precision-cast units are made with special heat treated rocker arms and case-hardened pins to ensure long-lasting performance. We use upgraded seals and pump diaphragms for compatibility with modern multi-fuel blends. Every single mechanical fuel pump is 100 Percent tested throughout the entire manufacturing process for worry free, out-of-the-box performance.
