Note that you can install a fuel pump yourself, but it takes mechanical skill and the correct tools to do this safely because of how tricky working on one is. This design makes fuel pump replacement far easier than on vehicles with tanks mounted outside the car, especially when it comes to accessing a blown (and often justifiably dangerous) combat-zone carcass. Usually it means extracting the fuel tank altogether – a 2-to-4 hour job, depending on the vehicle. The labor charge alone is typically $200 to $500, and so a few drivers with some mechanical proficiency may consider going the DIY route in order to save money.
Essential tools for this job include a jack and jack stands to raise the vehicle, fuel line disconnect tool in addition to your typical mechanics tool kit – with something like an electric drill making it easier. Without these tools, the job is much harder and could cause a potentially high risk of serious damage to your pump or fuel lines. Ventilation is critical, and making sure fumes do not make their way inside the building no matter what must be emphasized along with safety concerns as gasoline can catch fire. Automotive experts have advised to do this in a well-ventilated spot, to prepare with the fire extinguisher nearby and that if sparks are avoided by leaving the battery disconnected for example.
This is a several-step process including depressurizing the fuel system, removing the tank, and disconnecting electrical connections and lines for high-pressure fuel. Mistakes during these steps can cause fuel leaks or incorrect pressure, which could contribute to engine-performance woes for those less experienced. Forcing all the lines is important for your pump to perform at about 40-60 psi, depending on what kind of engine you have. Fuel flow is vital, especially in high-performance vehicles as incorrect installation can lead to fuel delivery issues at higher RPM levels.
Installation kits from companies such as Bosch and Walbro can help, but even with these helping hands having a professional install the unit bisa boon. These installations are a testament to precision — the late, great automotive pioneer Henry Ford once said “Quality means doing it right when no one is looking.” Despite that it is likely to set up a Fuel Pump all on your own, most truck drivers choose specialist installation guaranteeing the security and trustworthiness. This itself takes knowledge and a good deal of attention to detail due preventing potential performance issues so this is more an advanced project as you need a fair understanding in automotive mechanics.
