Product Details
AutoMeter is well-known for making reliable gauges and accessories for performance vehicles. This fitting adapter is a small but important piece for anyone running fuel pressure or nitrous pressure gauges. It connects a -4AN line to a 1/8" NPT port, and its main job is to help smooth out those rapid pressure changes you can get with fuel systems or nitrous oxide injection.
By slightly restricting the flow, this adapter helps dampen pressure spikes and fluctuations. This makes your gauge needle much steadier, giving you a more accurate and easier-to-read pressure reading. It's made from steel, so it's built to handle the pressures involved in these types of systems.
