Jet Fuel Injection Pressure Regulator

Jet Performance Fuel Injection Pressure Regulators: Precision Fuel Control for GM Engines

When it comes to squeezing every bit of performance out of a fuel-injected engine, fuel pressure is one of the most overlooked tuning variables. Jet Performance Products has been engineering performance solutions since 1969, and their lineup of fuel injection pressure regulators reflects decades of hands-on experience with GM throttle body injection (TBI) and tuned port injection (TPI) systems.

Why Fuel Injection Pressure Regulators Matter

A fuel injection pressure regulator controls the pressure at which fuel is delivered to the injectors, ensuring the engine receives a precise and consistent fuel supply under all operating conditions. Stock regulators are factory-set and non-adjustable — and over time, weakening internal spring tension can reduce fuel pressure, costing you both power and fuel efficiency. Jet addresses this problem directly with regulators that give you full control over fuel delivery.

Jet's Adjustable Billet Aluminum Regulators

Adjustability is the defining characteristic of Jet's fuel pressure regulator lineup. Unlike OEM units, the Jet TPI Billet Aluminum Adjustable Fuel Pressure Regulator provides the ability to adjust fuel pressure for maximum efficiency and horsepower gains. Factory TPI regulators are not adjustable and wear out over time due to weakening internal spring tension, which reduces power and mileage — so stock vehicles with high mileage can restore lost power simply by replacing the regulator, while performance-built motors benefit from the ability to precisely meter fuel delivery.

The Jet regulator is a direct replacement and features a steel insert on the adjuster to prevent stripping unlike other designs, and is precision machined out of billet aluminum by Jet's in-house CNC machine shop. This means tighter tolerances, a more durable construction, and a regulator that stands up to hard use on the street or strip.

For TBI applications — particularly the popular GM truck and SUV platform — Jet offers the 61510 TBI Fuel Pressure Regulator Kit, a TBI fuel regulator kit engineered for GM V6 and V8 applications. The adjustable TBI billet unit covers 1987–1995 GM fitments and operates in the 10–20 PSI range, making it a natural fit for 4.3L, 5.0L, 5.7L, and 7.4L engines found in Chevrolet and GMC trucks and SUVs of that era.

Rooted in Racing, Built for the Street

Jet Performance Products started life as an engine building and carburetor shop focused on providing racing engines and carburetors to local Southern California drag racers, and in the last 50 years the company has developed a large range of performance products as their engineers continue to develop new and innovative products to enhance your driving feel and experience. Everything is manufactured in the USA. That domestic manufacturing commitment extends to their fuel pressure regulators, which are CNC-machined in-house rather than sourced from overseas suppliers.

Whether you're restoring lost performance on a high-mileage GM truck, dialing in a freshly built TPI small-block, or simply upgrading a tired OEM unit, Jet's adjustable fuel injection pressure regulators offer a straightforward, proven solution backed by more than five decades of performance engineering expertise.
