How to Install a Fuel Pump for a 1997 Chevy Blazer
The fuel pump in the gas tank of a 1997 Chevrolet Blazer takes the fuel in the tank and delivers it to the engine via the fuel lines. When the fuel pump goes out, the engine becomes starved of fuel. To fix the problem, the fuel pump has to come out and be replaced with a new one. The process should take about two hours.

Open the hood. Connect a fuel pressure gauge to the Schrader valve. The Schrader valve is on the top of the engine, connected to the fuel line. Put the drain hose from the fuel pressure gauge into a gas can. Push the pressure relief button on the gauge and allow the fuel to empty into the can. Once the pressure is gone, remove the fuel pressure gauge.
