That said, replacing the Fuel Pump might be a DIY-friendly task for those with at least moderate mechanical experience. However, it all depends upon how the pump is situated in your vehicle. Mostly in modern-day vehicles, the Fuel Pump is situated inside the fuel tank itself, thereby making access a wee bit more difficult. Generally speaking, replacing an in-tank Fuel Pump requires that you lift the vehicle, drain the tank, and disconnect fuel lines-a process that might take 2 to 4 hours. If the car has an access panel, usually behind the rear seat or in the trunk, it will greatly facilitate the work, which can take 1 to 2 hours.
For the do-it-yourselfers who enjoy trying their hand at most things, having the right kind of tools would be good enough. A toolkit should contain some elementary tools, a jack to raise the car, and safety precautions while handling fuel. A Fuel Pump should cost in the range of $50-$300 depending on the make and model of your car. Savings on labor for a DIY job can be in the range of $200-$500. One of the main reasons people try doing this is the incentive on labor costs.
In 2020, Ford recalled upwards of 1.3 million vehicles for faulty fuel pumps; many of the drivers chose to handle the replacements themselves. This would prove that with the right preparation, even non-professionals can handle the task, but caution should be used when working with flammable liquids and a pressurized fuel system.
This alone usually involves much finer handling and adjustments, whereas installation in high-performance vehicles that have upgraded fuel systems would definitely need the installation of a high-flow Fuel Pump, such as Walbro 450 LPH. In such setups, the major understanding needed is about the fuel pressure system and matching compatibility with the proper injectors and regulators.
As David Vizard, automotive expert, said, “Working on your fuel system can save time and money, but safety has to be number one.” Following safety precautions, like disconnecting the battery and working in a well-ventilated area, is part of effectively completing a do-it-yourself replacement of the Fuel Pump.
