Step 5. Make sure fuel cap is fully tightened. Carefully turn the tank upside down on a soft cloth to protect it and remove the 5 screws that hold the fuel pump in place with a T25 torx bit.
Step 6. Remove the fuel pump assembly from the tank, this may take a little finagling but be patient and note how it comes out to make it easier to go into the new Cole Foster Gas Tank.
Step 7. Check the fuel pump plate gasket to see if it is in good shape or if it needs replaced. It should be seated properly, flat on each side, with the rounded portions keeping it seated in place in the groove.
