The area around the fuel pump lock ring on the top of the fuel pump module has changed, so the previously Essential GM-45747 fuel pump lock ring wrench no longer fits 2018 Equinox models. GM-52075 fits the fuel pump lock ring, allowing it to be removed and installed whenever fuel pump module service is required. GM-52075 will supersede GM-45747 for future applications. Using unapproved methods can damage the fuel pump module, lock ring, or fuel tank.
