The fuel system also includes a high-pressure regulator and a fuel pressure gauge, allowing you to easily monitor and adjust fuel pressure. The regulator is adjustable from 1 to 10 psi, ensuring that you can dial in the exact fuel pressure that your engine requires for optimal performance.

The Holley 20-220 Mid-Mount Fuel System is constructed from high-quality materials and is built to last. The fuel tank is made from heavy-duty 6061-T6 aluminum, which is both strong and lightweight. The fuel lines are made from reinforced PTFE material, which is resistant to fuel, oil, and coolant, ensuring that they can withstand the rigors of high-performance applications.

In summary, the Holley 090127056479 20-220 Mid-Mount Fuel System is a high-performance fuel delivery solution designed specifically for the General Motors Gen LT4 engine. With its mid-mount design, high-capacity fuel pump, adjustable fuel pressure regulator, and heavy-duty construction, this fuel system is an essential upgrade for any LT4 enthusiast looking to maximize the potential of their engine and take their performance to the next level.
