How to Find the Right Fuel Pump for Your Car?

STARS AUTOMOTIVE CAR FUEL PUMP — Finding a suitable fuel pump for your vehicle requires looking into the specifications such as fuel pressure, flow rate, fuel type compatibility, and fitment requirements. The majority of fuel injected engines require pumps that can hold pressures from the 40-70 PSI range to provide adequate fuel. It is also important to match the correct pressure specification, as an underperforming pump can lead to lean conditions and misfires/poor engine efficiency. High-flow fuel pumps (greater than 250 liters per hour (LPH)) are used in vehicles with performance modifications or turbochargers to supply the increased amount of fuel.

Pump selection is also dependent on the fuel-compatible type. Ethanol is a common fuel in many modern vehicles and it is not friendly to pumps that are not specifically designed for ethanol, which are prevalent in the industry. Pumps that are compatible with ethanol are usually made of corrosion-resistant materials such as stainless steel, making them more reliable in these situations. For vehicle types that utilize E10 or E85 fuel blends, mechanics recommend opting for an ethanol-ready pump, which can last up to 30% longer than standard pumps–reducing how often you need to replace it.

That fits as it should, matching the inlet and outlet, which are typically 8mm or 10mm for most standard vehicles. Also the electrical compatibility of the pump, since most systems need a consistent 12–14 volt supply to operate properly. To minimize the chance that wiring will need to be changed around, relays and connectors will have to match the electrical needs of the pump. An insufficient pump can tax the electrical system, shortening burn life.

Cost and warranty are also important factors. Fuel pumps generally run anywhere from $50 to $300 depending on quality and features, and a great warranty — typically up to 100,000 miles — suggests a well-built pump that can handle the rigors of everyday driving. Not that all of those are going to be well and good, but as Ed China, automotive expert and presenter will tell you, “A decent quality fuel pump, [is] designed to run as long as the car itself,” so they’ll be a long lasting piece of history.

Choosing a high-quality, genuine replacement Fuel Pump with the right specifications allows your vehicle fuel system to work dependably, improving performance, lifespan and avoiding expensive repairs.
