Carquest Fuel Pumps are performance-tested premium fuel pumps that ensure long life through quiet and precise operation.
If you’ve tried to find the fuel pressure regulator on many late-model engines by looking in the engine compartment, you won’t find it there because the regulator has been relocated to the fuel tank. Engines with “returnless” electronic fuel injection (EFI) systems have the regulator inside the fuel tank.
Nothing is worse than a comeback after a fuel tank has been dropped. Discovering that the fuel tank needs to be dropped again to address a problem can kill shop productivity and profitability. Below are tips that can help you avoid comebacks and dropping the fuel tank for a second time.
In extremely cold weather (approximately -30° C), a customer may experience an engine no-start/no-crank condition due to a frozen main relay and/or fuel pump relay.
10. Strainer Blocks Fuel-Level Sender A fuel pump inlet strainer may be installed that is interfering with the travel of the fuel-level sensor’s float arm, which causes an optimistic fuel level reading. Dented fuel tanks may also cause a false reading by pushing the fuel-level sensor and fuel pump inlet filter above the remaining fuel
Direct injection is becoming standard on more and more late-model vehicles. These systems can be a diagnostic challenge, but with the right foundation, problems can be solved profitably. Years ago, all a low-level technician needed to diagnose a fuel problem was a set of “noid lights,” a fuel pressure gauge and maybe a meter. These
The ancient Greek philosopher Heraclitus said that there is nothing permanent except change. Greek history aside, it’s easy to spot change in our current market because vehicle fuel delivery technology has evolved to include conventional, pulse-modulated and direct fuel injection fuel delivery systems, with each having a specific set of components and testing issues.
