Where is the 2011 chevy traverse fuel pressure regulator located?

The 2011 Chevy Traverse fuel pressure regulator is built into the fuel pump assembly and is in the back of the tank. The regulator in this case controls the pressure before it enters the lines to travel up to the fuELRail. Chevrolet has integrated more components into the fuel sending unit over the years. This can be a good thing because they are designed to last longer, but it can also be tricky because individual components cannot be inspected and replaced as easily. I recommend checking the fuel pressure at Your fuELRails to make sure that it is correct. If it is low or high that may lead to the engine running lean or rich.
