If your 1993 Chevy Blazer is getting bad gas mileage and the motor is stalling out unexpectedly, it might be that you need a new fuel pump. Although replacing a fuel pump on a Chevy Blazer is a moderately challenging task, it can be done well with the right preparation and tools. It will be useful to obtain a Chilton or Haynes Manual for your 1993 Chevy Blazer.
Tools Used: Tools, Socket set, Torque wrench, Fuel pump, Shop rags, Siphoning kit, Jack, 2 jack stands, Brass punch, Transmission jack, Latex gloves (optional), Safety mask, Class B fire extinguisher, Fuel container
Remove the Fuel Pump – Directions
Begin by disconnecting the negative side of the battery. You will also want to place the tools you will need to complete the project near your work area. Using a jack, lift the rear of the vehicle and using jack stands, securely support it. Take the fuel cap off and use the siphoning kit to remove the fuel from the fuel tank. If you spill any gasoline, immediately clean the area. Safely store the gas in a cool area away from sparks.
Remove the fuel tank shield if your Chevy Blazer has one. If not, proceed to disconnect the clamp from the fuel filler pipe which is located near the fuel tank. Detach the filter pipe from the filler pipe.
