The complexity of an internal combustion engine means that there are a number of monitors and regulators designed to keep the engine running at peak efficiency. The introduction of fuel injection many decades ago increased the complexity of engines while making them more efficient and powerful. If you want to keep your engine running as well as possible, you need to keep the gauges and regulators in perfect shape and use the best models available, which is why you should replace your aging fuel pressure regulator with an Accel fuel pressure regulator. Accel has been one of the top names in engine performance and management for over a quarter of a century. The Accel fuel pressure regulator is a premium quality component that is able to provide the most precise monitoring and control even under the most demanding conditions. Accel fuel pressure regulators come in several models. The very best Accel fuel pressure regulators are designed to be adjustable, allowing you the ability to regulate your fuel pressure to meet differing conditions. Accel also has universal Accel fuel pressure regulators that are non-adjustable, but are still able to provide excellent and stable fuel delivery at a constant pressure.
