Gauge style (PSIg) Pressure Sensors AEM offers high quality PSIg sensors in 100, 150, 500, 1,000,
and 2,000. Gauge style pressure sensors reference pressure above atmospheric pressure. When exposed to atmospheric
pressure, gauge style pressure sensors will read 0 psig. Gauge style pressure sensors are commonly used for oil pressure,
fuel pressure, brake pressure, nitrous pressure etc.
Which Pressure Sensor is right for you?
There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool.
For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper
should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if
we think about it in these terms:
Brass Pressure Sensor = Ruler Use a Brass Pressure Sensor where you need a good reference to what
pressure is being seen. Example: Brass Pressure Sensor used for a Boost Gauge – Reference/Information for knowing
manifold pressure, not for ECU calibration.
Stainless Pressure Sensor = Caliper Use a SS Pressure Sensor where you need exact details of the
pressure. Example: MAP Sensor information for the ECU – Calibration/crucial information for the ECU.
The Universal 12 Position Trim Pot is for use on virtually any Engine Management System, such as the AEM EMS. Use the Trim
Pot to adjust a number of trims, including ignition timing, fuel, boost, etc. The Universal 12 Position Trim Pot includes:
12 Position Trim Pot with Flying Lead, 2 Brushed Silver Trim Position Decals with ranges from -5 to +6 and 0 to +11,
Blue/Red/Black AEM Logo Knob Decals & Blue/Red/Black Colored Knob Decals.
Absolute (PSIa) Pressure Sensors AEM offers high quality stainless steel PSIa sensors in 15 (1BAR),
30 (2BAR), 50 (3.5BAR), and 75 (5BAR). PSIa is referenced to absolute zero. Absolute zero is the pressure measurement
when all the pressure exerted by the atmosphere has been removed. The most common use for absolute pressure sensors
is reading manifold pressure. PSIa sensors are required if you wish to measure vacuum. A PSIa sensor will read about
14.7 PSI when the sensing element is exposed to atmospheric pressure at sea level however they can be recalibrated
to read zero at atmospheric and a negative number at values less than atmospheric pressure.
The AEM E85 Fuel Pump is designed for in-tank installation on high performance naturally aspirated and forced induction
AEM's E85 Fuel Pump features robust internal construction that is designed to withstand the low lubricity characteristics
of ethanol and methanol fuels, and has been tested to work with ethanol fuels up to E100, methanol fuels up to M100
and all types of gasoline.
The AEM E85 Fuel Pump is compact, with only a 39mm diameter and that fits most applications. Offered in various inlet
styles to ease installation, included with the fuel pump is a wiring harness, pre filter, internal fuel hose and
clamps, end cap and rubber buffer sleeve. Every AEM E85 Fuel Pump is flow tested at 43 PSI before it is packaged
AEM’s 320lph E85-Compatible High Flow In-Tank Fuel Pumps feature robust internal construction that is designed to withstand
the low lubricity characteristics of ethanol and methanol fuels, and are tested to work with ethanol fuels up to
E100, methanol fuels up to M100 and all types of gasoline.
The AEM 320lph E85-Compatible High Flow In-Tank Fuel Pump is designed for in-tank mounting on high performance naturally
aspirated and forced induction vehicles. It features a compact 39mm diameter that fits most applications and an offset
inlet design that eases installation.
The 320lph E85-Compatible High Flow In-Tank fuel pump includes a wiring harness, pre filter, internal fuel hose, clamps,
end cap and rubber buffer sleeve. Every AEM 320lph E85-Compatible Fuel Pump is tested to flow 320 lph at 43 PSI before
it is packaged for sale.
The AEM 380lph High Flow, High Pressure Fuel Pump for high performance naturally aspirated and forced induction EFI vehicles.
The High Flow, High Pressure Fuel Pump can be installed externally or in-tank using optional hardware that is sold
separately. It utilizes the industry standard “044 Style” envelope and -10 AN female inlet and -6 AN female outlet
connections for easy installation on new applications and for quick replacement of existing competitor fuel pumps.
The 108-50-1005 fuel pump delivers incredible performance and value.
AEM’s 380lph High Flow, High Pressure Fuel Pump is capable of supporting over 1,200 HP normally aspirated and a whopping
860 HP at 30 psi boost!* It flows 380 lph (100 gph) at 43 PSI, 340 lph (90 gph) at 73 PSI, and 270 lph (71 gph) at
120 PSI. Complete flow curves from 35 to 120 PSI and current draw vs. fuel pressure charts are available in the specs
The AEM 380lph AN Fittings High Flow Fuel Pump is rated for use with ethanol-blended fuels, (E85/E90) and all types of
gasoline, but pump life will be diminished if used with 100% ethanol fuels. The inlet thread is a -10 AN female ORB
(O-ring port fitting) and the discharge is a female -6 AN ORB (O-ring port fitting).
A male -6 to -8 AN discharge fitting with integral high pressure check valve, terminal nuts, terminal boots and installation
instructions are included. Optional accessories that are sold separately include a -10 ORB fitting inlet pre-filter
(for use with in-tank installations), and both -8 and -6 discharge adapters without integral check valves. Accessory
fittings are hard anodized.
Optional Inline High Flow Fuel Pump Accessories
*Power rating given using gasoline and assuming a base fuel pressure of 43 PSI, 13.5v at the pump, 6.2 lbs/gal with a
BSFC of 0.65. Boost fuel pressure is assumed to be the base pressure of 43 PSI + boost pressure. Flow capability
for horsepower support is ultimately dependent on fuel hose diameter, and system electrical voltage and amperage
AEM's wideband O2 UEGO AFR replacement sensor and stainless-steel, finned, stand-off bung kit includes only a replacement
Bosch 4.2 LSU Wideband UEGO sensor and stainless steel tall manifold bung. It is designed for installation and use
with the AEM 4-Channel Wideband UEGO Controller, and forced induction (turbo and supercharged) applications.
These sensors have a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically
created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output. The wideband
sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration
when used with an AEM wideband AFR controller.
AEM's Air Inlet Temperature Sensor Kits (AIT) senses the air temperature on the inlet side of the engine.
