EFI Regulator & Gauge Kit w/Fittings

The Aeromotive EFI Regulator & Gauge Kit with Fittings (Part #13130) is a complete fuel pressure regulation and monitoring solution for electronic fuel injection systems operating between 40 and 75 psi. This in-line bypass regulator combines the critical functions of pressure control and real-time gauge feedback into a single integrated package, eliminating the need for separate component sourcing and installation.

The kit features 6 AN female O-ring fittings for both inlet and outlet ports, with a dedicated 6 AN female O-ring return line and 1/8-inch NPT gauge port. This configuration allows precise fuel pressure adjustment while the included gauge provides instantaneous visual verification of system pressure during operation and diagnostics. The black and clear anodized aluminum construction offers both durability and visibility of internal fuel flow. The bypass design ensures consistent pressure delivery across variable load conditions, preventing fuel starvation at high flow rates while protecting injectors from excess pressure spikes.

This regulator kit is engineered for compatibility with gasoline, diesel, and E85 fuels, making it suitable for a wide range of engine platforms from naturally aspirated to forced-induction applications. Serious builders and tuners rely on this type of integrated regulator-gauge assembly to establish baseline fuel system performance before dyno testing or road validation. The complete fittings package eliminates adapter hunting and installation delays common when regulator and gauge components are purchased separately.

Aeromotive's fuel system components are recognized throughout the performance and motorsports communities for precision engineering and long-term reliability. The 40–75 psi operating range covers the standard fuel injection pressure window for most carbureted-to-EFI conversion projects and modern engine builds, ensuring compatibility with popular ECU tuning platforms and fuel pump specifications.
