Seeing the exact fuel pressure on your vehicle can mean the difference between extracting the most performance safely and expensive failures. AutoMeter’s Mechanical Fuel Pressure Gauge will precisely measure your exact fuel pressure at levels of accuracy previously unheard of even in professional gauges. Designed for fuel injected or carbureted applications, a simple -4an connection makes installation easy. Don’t take chances with your investment; a precise fuel pressure gauge could be the cheapest insurance you’ve ever bought. For the safety of the operator, it is not recommended that Fuel Pressure gauge are installed inside the cabin of the vehicle. Optional fuel isolators are available for both carbureted and fuel injected applications.

Just bought one of your 4412 with intent on running it on my daily driver. Outside the cab. Did not know that it was not waterproof. I guess i will eat that guage. My question is this liquid filled gauge waterproof/freezeproof. Thanks....

Asked by: cooter355
Yes, the liquid filled gauges, like the 5412, would be 100% sealed and ideal for outside mounting/exposed to the elements. No issues with freezing. The liquid is silicone and you will have no gauge issues above -50 degrees

looking for a fuel pressure isolator compatable with methanol. Do you offer one. No place to mount gauge outside cabin. Need isolator to run it inside cabin. Thanks
