Moroso Electric Fuel Pump Spring - Holley - 12-19psi

This Moroso electric fuel pump spring is designed to work with Holley fuel pumps, allowing you to fine-tune your fuel pressure. It's made to adjust pressure within the 12 to 19 psi range, which is crucial for getting the right amount of fuel to your engine under various conditions. A well-set fuel pressure ensures your engine runs smoothly and efficiently, especially when you're pushing it a bit harder.

The spring itself is a simple but effective component. When you're rebuilding or tuning your fuel system, having the ability to adjust pressure within this specific range can make a notable difference in performance and drivability.
