There are two broad types of fuel pumps; electric fuel pumps that are mostly used in fuel injection systems, mechanical fuel pumps used in carburetor systems. The pump mainly serves as the pressure and filtration mechanism of the fuel to achieve the optimal combustion. Performance fuel pumps are rated in GPH or LPH and depending on the engine horsepower and hours of usage it demands a certain flow rate. However mechanical pumps has been common, electric pumps has more pressure and are more efficient, latest software uses pulse-width modulation for long lasting and low power consumption. In summary, the fuel pump plays the critical role of providing the engine with suitable quantities and pressures of fuel as required.

- Q: How do you remove the fuel pump/sending unit assembly on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?A: Start by relieving fuel system pressure and detach the cable from the negative battery lead to remove the fuel pump/sending unit assembly. Afterwards, remove the Fuel Tank and gently tap on the locking cam until tabs co-align with recesses that will release the assembly. Lift it out of its place in the tank, moving any necessary components over to a new fuel pump module assembly.

To install, reassemble the sending unit bracket assembly back onto the fuel pump as well as insert an assembly into a gas tank and finally put back all parts of fuel tank.
- Q: How to check the fuel pump output and pressure for Chevrolet Blazer,S10,GMC Jimmy and Sonoma?A: To check the fuel pump output and pressure, relieve the fuel pressure. Next, Install a fuel pressure gauge on the fuel rail, location varies depending on the system. Turn the ignition switch on without starting the engine and note the reading on the gauge as the fuel pump runs for about two seconds. The pressure should hold steady within the specified range. Start the engine and let it idle at normal operating temperature, with the pressure expected to be lower by 3 to 10 psi. If the pressure does not drop as expected, apply a vacuum to the pressure regulator and if it drops, repair the vacuum source or replace the regulator. If the pressure is not within specifications, check for a vacuum to the regulator or a pinched/clogged fuel return hose. If the pressure is still low, change the fuel filter and if it remains low, install a fuel line shut-off adapter to test the regulator. If the pressure is still low with the return line restricted, there may be a leaking injector or a faulty fuel pump. To check the fuel pump's electrical circuits, verify that the pump runs by listening for a whirring noise when the ignition switch is turned on and when the engine is started.
