0-700 kPa differential pressure sensor (5V supply, 0.2-4.7V output) Also included: an MV type pneumatic connector with 1/8 NPT male thread, and a 170mm (6.7 inch) long tube

• the high pressure side (hollander nipple) has fluoro-silicone gel coating (on the piezoresistive membrane inside) which protects against "harsh media". The datasheet does not specifically mention any specific fluid, we successfully use for gasoline and ethanol fuel. Connect with 180C capable tefzel 6/4mm pneumatic tube (the 85-90C tube would be dangerous for this). The sensor nipple must point down, so the trapped air cannot escape and fuel cannot reach the sensor. (the trapped air in this tube can provide some fuel pressure accumulation). The sensor must be secured properly, not hanging on the fuel-hose or the wires
• the low pressure side (simple nipple) can be connected to manifold pressure (seems logical, as fuel pressure regulator also references manifold pressure, this gives a stable reading). Alternatively left at ambient pressure.

• pin1: VOUT 0.2V - 4.7V (0-700 kPa). Slope is 700kPa / 4.5V (that is 778kPa / 5V)
• pin2: GND
• pin3: +5V supply (consumes appr 7mA)
