Full Sweep Electric Fuel Pressure Gauges
Marshall Instruments electric fuel pressure gauges use high-end accurate senders, are easy to install and keep dangerous fluids out of the cockpit.

Why Use a Fuel Pressure Gauge
Fuel pressure gauges indicate the pressure in the fuel system supply. Proper pressure is critical for proper air/fuel mixtures in both carbureted and fuel injected applications. Loss of fuel pressure can cause an extremely lean air/fuel mixture and costly engine damage.

Fuel pressure gauges:

  • Indicate a loss of fuel system pressure or system malfunction
  • Indicate when a fuel system upgrade is required on systems where modifications have been made
  • Aid in tuning adjustable fuel pressure regulators
  • Monitor fuel system pressure during nitrous oxide activation, as the additional fuel system demand can be substantial

You will need to be aware of the desired fuel pressure range. Generally, carbureted applications operate around 7 psi and require a 15 psi gauge. Most modern fuel injected systems operate over 40 psi. You should check with your engine builder for the operating fuel pressure range of your system. If using nitrous oxide you will need to ensure you have accounted for the additional fuel required during nitrous activation. NOTE: If modifications have been made to your engine you need to verify that your fuel pump is capable of producing the required pressure and volume required to maintain the proper air/fuel mixtures.

The needle will indicate the current fuel pressure on the application being monitored. This reading should remain fairly steady and may vary with engine RPM depending on the particular application. You will need to know what to expect from your system.

If the fuel pressure drops below the desired limits, you should, as quickly as possible, determine and fix whatever has caused the loss of pressure before engine damage occurs.

Direct Mount 1-1/2" Shock Proof Fuel Pressure Gauges
Keep an eye on important pressure levels with our 1 1/2 in. fuel gauges. Ideal for fuel pressure readings on carbureted or fuel injected engines, our 0-1500 PSI gauge is ideal for nitrous systems. Available in a variety of pressure ranges and dial styles. Most gauges are liquid filled to provide vibration resistant readings. Fuel pressure gauges have a center back 1/8 in. NPT male fitting and mount on any fuel pressure regulator line with a 1/8 in. NPT pressure port.
