The AEM Digital 0-100PSI Fuel Pressure Gauge allows you to monitor pressure to 100PSI on an easy to read gauge.
A very important aspect of tuning is fuel pressure. A drop in pressure can result in a lean condition that can quickly cause detonation and engine damage. An Air/Fuel Ratio gauge will let you know are running lean, but can’t tell you why. Now you’ll know if it’s a fueling issue or something else.
Now you can know if your pressure has started to drop before real damage can occur.
