What and where is the R & R Fuel Tank Pressure sensor located? Is this near tank

The fuel tank pressure sensor is located on top of the gas tank. You will need to remove the gas tank to replace the sensor. If you have never replace a gas tank before be sure use cation. There are fuel lines, hoses, and wires that need to be removed otherwise damage could occur to the parts not to mention you will be working with a flamable liquid.
