Make fuel checks simple with Aeromotive's billet fuel sample valves. Depending on the model you select, the aluminum units can install into your 1/8 in. NPT inlet port with threads or quick-connect attachment. Some contain a stainless steel barb fitting for extension hoses and rotate 360 degrees for easy sampling. A spring-loaded safety feature keeps the sample valve sealed when unlocked, and rotates into a locked position when it's time for racing. When a fuel sample is required, simply rotate the valve to the unlocked position, press down for a fuel sample, re-lock, and go race!
