Replacing the fuel pump on a 1989 S10 pickup is a complex task. The first step is to decide whether to replace the whole unit or just the pump itself. The next step is to remove the bed, disconnect the lines, and pull out the fuel pump assembly. It is also possible to drop the gas tank and replace the pump in the tank, but this is more difficult.

What You'll Learn
Dropping the gas tank
First, you need to remove the bed. The bolt locations are easy to find underneath. Unscrew the filler neck and taillights from the bed. Once the bed is off, pop the lock ring off from around the fuel pump assembly, disconnect the lines (be careful not to leak the gas) and then pull the fuel pump assembly out. Take care not to spill the fuel out of the pump assembly itself.
Once the fuel pump assembly is out, you can either replace the whole thing or buy the separate parts to replace only the pump. Either method is fairly easy but replacing the whole unit is much more expensive.
