Regulator Service Kit

The Aeromotive Regulator Service Kit (MPN 13002) is an essential maintenance component for serious fuel system builders and performance mechanics working with Aeromotive fuel regulators. This rebuild kit supplies the internal sealing and fastener components needed to restore regulator function when diaphragm degradation or corrosion compromises flow control or pressure stability. Whether you're refreshing a high-mileage carbureted engine, servicing a fuel-injected street build, or maintaining a professional shop's test bench regulator, this service kit extends equipment life and eliminates the need for costly full regulator replacement.

Inside this kit you'll find factory OEM-equivalent diaphragm material and precision fasteners engineered to Aeromotive's original specifications. The diaphragm is the critical wear component—over time, fuel and ethanol exposure, temperature cycling, and pressure cycling cause rubber degradation, leading to fuel weeping, inconsistent pressure regulation, or complete loss of control. By replacing the diaphragm and associated hardware, you restore the regulator's ability to maintain stable fuel pressure across your entire RPM and load range, which is non-negotiable for carburetor tuning accuracy and fuel-injection system stability. The compact 4.9 x 2.4 x 6.65 inch package fits easily in a tech bag or parts drawer, and the 0.18 lb weight reflects a focused, no-waste design.

Mechanics and engine builders choose this kit when they want to keep proven Aeromotive regulators in service rather than retire them. The rebuild process takes 10–15 minutes with basic hand tools, making it ideal for field repairs, race weekend maintenance, or workshop restocking. This service kit is compatible with Aeromotive's full range of fuel regulators and works on both mechanical and electronic pressure-control applications, making it a versatile addition to any performance garage or professional shop inventory. Buy this regulator service kit when pressure stability is critical and downtime must be minimized.
