AEM Electronics Fuel Pulse Damper - 40-70psi

The AEM Fuel Pulse Damper is designed to smooth out pressure fluctuations in your fuel system caused by injector and fuel pump activity. It works alongside your fuel pressure regulator to stabilise pressure at the rail, particularly in setups running large injectors or high-output pumps.Discover the key features of this fuel pulse damper and how they contribute to performance and reliability:Internal Stainless Steel Spring Assembly: A preloaded stainless steel spring balances the diaphragm response against sudden pressure spikes, helping to maintain stable fuel delivery across varying load conditions and reducing the chance of inconsistent injector flow.Fluorosilicone Diaphragm: This chemically resistant diaphragm withstands exposure to all fuel types including ethanol and methanol blends, ensuring long-term durability and consistent operation across a wide range of fuel system configurations.CNC-Machined Billet Aluminium Housing: The anodised billet aluminium body resists corrosion and thermal stress, giving you a compact and robust damper that performs reliably in high-temperature engine bays.1/8" NPT Port on Body: The additional port allows you to install a mechanical pressure gauge or sensor directly into the damper, giving you easy access to live fuel pressure data for tuning or diagnostics.Male AN -6 ORB Fitting: This standardised fitting simplifies installation with most aftermarket fuel systems, reducing the need for adaptors and ensuring a secure, leak-free connection.This unit helps you achieve more consistent fuel pressure during transient load changes, which is critical for maintaining precise air-fuel ratios during tuning or hard driving. Its compact design and broad fuel compatibility make it a valuable addition to any upgraded fuel system setup. The robust construction and integrated sensor port make it a smart choice for simplifying your fuel system layout while improving stability.
