Pin	Function
1	Fuel sender (-)
2	Fuel pressure sensor signal
3	Fuel pressure sensor ground
4	Ground
5	CAN_LOW
6	Fuel sender (+)
7	-
8	Fuel pressure sensor (+)
9	CAN_HIGH
10	Battery (+)

Also check that the resistance changes smoothly when the float moves from "E" to "F".

Position	Resistance (Ω)	Capacity [l (U.S gal., U.S.qt., Imp.qt.)]
