CNG level project in Car

hi
i am working on the project in which i want to get level of CNG in Car and want it to digital and send it through SMS .i have some problem concern about this
i am woking IN MickroC
the CNG car used Slider resistor having two wire only. the silder on the top change value
https://www.alibaba.com/showroom/Variable_Resistor.html
as shown in figure i want a circuit in which i can change this in to voltage and can interface to pic18f452 ADC

plz help me

Please any one help me out


Circuit diagram for the resister to voltage conversion

Requirement for the circuit

• The value of resistor goes to 11k at maximum value of pressure
• The value goes to zero when there is no pressure in CNG kit.
• 5V is used to define the output
 5V shows maximum pressure
 0V shows zero pressure

so plese help me
i want to select the value of R1 so please guide me

here it is but in this approach u have to use 2 Regulated supplies 5 and 12

0 volts for no pressure
5 volts for maximum pressure
