Mallory 29806 - Mallory Fuel Pressure Gauge Isolator Kit

Mechanical gauges offer maximum accuracy but can be a safety hazard. Whether you want to monitor fuel, oil, or even coolant pressures, you can do it safely without the risk of spraying fuel, hot oil or coolant all over your interior. Easy to install, just hook a pressure line from your engine compartment to one side of the CNC machined Mallory Pressure Isolator and fill the line from your gauge to the other side of the isolator with a 50-50 mix of antifreeze and water. Your gauge reads the pressure instantly and accurately, but safely. Isolator kit includes the mounting brackets, -4AN fittings and is compatible with gasoline, alcohol/methanol, oil or even coolant. The maximum recommended pressure is 80 psi.
