Many of our customers at AAM asked for an easy solution when mounting fuel pressure gauges, fuel pressure gauge isolators, or fuel pressure sensors to the factory fuel system. We responded by developing our AAM Competition Fuel Pressure Gauge Adapter block with a 1/8” NPT tapped hole that bolts neatly onto the factory fuel line (virtually all fuel pressure gauges/isolators are threaded 1/8” NPT). Our Nissan GT-R fuel pressure adapter kit eliminates the need to cut into the factory fuel line for a fuel source – so you won’t have to worry about fuel line leaks down the road. The AAM Competition GT-R Fuel Pressure Gauge Adapter also comes with a Fuel Pressure Gauge capable of reading up to 6 Bar of Pressure.
