The OEMTOOLS 25156 Fuel Pump Module Spanner Wrench removes and installs the fuel pump retaining ring holding the fuel pump module onto the gas tank. The fuel pump spanner wrench is fully adjustable for inside and outside grip. It applies forces to 2 sides of the cap at the same time, ensuring that all torque is translated into movement instead of being lost due to friction and resistance. Some rig up a temporary fuel pump removal tool out of things around the shop, but it pays off to use to use the right automotive specialty tools. Other methods can not only be difficult, time-consuming, and ineffective, but they can also risk costly damages. Using this specialty adjustable spanner wrench is simple. Use a 12 millimeter wrench to adjust the width of the arms to your application and then, when the spanner wrench is secure, use a 3/8 inch drive ratchet to tighten or loosen the ring. Repairs involving the fuel pump are always easier with the right tools. That's why automotive professionals and experts rely on the OEMTOOLS 25156 Fuel Pump Module Spanner Wrench.
