Monitoring the fuel pressure on your Cummins, Duramax or Powerstroke diesel is critical in maintaining peak performance and power. This is especially critical in performance street and modified diesels. Having an ISSPRO EV2 fuel pressure gauge, allows you to diagnose fuel system problems before they can cause harm to your expensive injection pump or fuel system. This is epecially true for the VP44 injection pump(1998.5 to 2002 Cummins 24V).
The Enhanced Visibility 2 (EV2) line of gauges by ISSPRO has set new standards for ease of viewing. What separates these gauges from the rest is the dished dial face and convex glass lens. The inside of the glass lens has an antifog coating which increases the readability of the gauge, especially at night. Even the case was designed to enhance night time visibility. The EV2 series are lit by long life LEDs (light emitting diodes).
HOW DOES THE SENDER WORK?
The ISSPRO R13044 fuel pressure gauge uses a high tech sender about the size of a pack of gum. (see photo) The electronic sender features an 1/8" male pipe thread that makes it easy to connect to your fuel source.
Inside the sender are two metal discs that are seperated and sealed. As pressure increases, the discs move closer to each other. The gap between the discs has an electrical circuit that measures capacitance. The output from the discs is an AC wave form. As the fuel pressure goes up, the capacitance goes down and visa versa.
Directly above the discs is a micro processor, also known as an applied specific integrated circuit (ASIC). The engineers at ISSPRO state that it is a very basic computer. The capacitance is measured by a single purpose integrated circuit, located on top of the discs, and converts the signal to a DC signal. This signal is sent to the stepper motor in the gauge. The stepper motor responds to the signal and gives you an accurate pressure reading. It's intereseting to note, CNC machines use stepper motors to control the ball screw movements. Pretty hi-tech stuff for a fuel pressure gauge!
SPECIAL INSTRUCTIONS FOR THE P PUMP
On 1994 to 1998 Cummins diesel engines, use the Tork Tek CBS010 for quick hook up to the Bosch P7100 injection pump. The banjo bolt gauge snubber features a 14mm thread and an 1/8" female pipe thread. The snubber will work on any fuel system that has a 14mm x 1.5 thread. Inside the snubber is a calibrated orifice that dampens the pressure spikes from the lift pump and will produce accurate gauge readings.
Please note the special installation procedure for Cummins diesels with the Bosch P7100 pump. This only applies to this group of diesels because of the pressure spikes created by the lift pump. This diesel is the only one that requires an additional orifice in the sender. When you checkout, make a note that you are using this gauge and electronic sender with the P pump, and we will make the modification free of charge.
Aftermarket electric fuel pumps (FASS and AirDog) are capable of 60 PSI of fuel pressure on high performance P pump applications. Normal pressure for standard street trucks is 30 PSI. If you are running close to 50 PSI of Cummins fuel pressure, I would suggest that you use a 0-100 PSI ISSPRO fuel pressure gauge. As a general rule, you want to choose an EV2 gauge with twice the pressure range of the fuel pressure you are running. This will increase the service life of your gauge.
Isspro has been a leader in diesel engine management for over 60 years. Don't trust your expensive diesel to cheap unreliable gauges. Keep an eye on your fuel pressure with a quality ISSPRO R13044 fuel pressure gauge from Tork Teknology.
