Replacing Fuel Pump In '89 Celica: Step-By-Step Guide

If you need to replace the fuel pump in your 1989 Toyota Celica, you'll first need to relieve the fuel pressure. If your car starts, you can do this by removing the fuse or relay for the fuel pump and letting the car idle until it stalls. Then, turn off the key and remove the negative battery cable to prevent sparks while you work. Next, drain the tank and remove it from the car, noting the position of the hoses and wires. Clean and dry the top of the tank, then use a non-metallic tool to remove the lock ring holding the tank unit in place. Now, carefully lift out the assembly and remove the old pump and filter. To install the new pump and filter, just follow these steps in reverse.
