Not all cars are compatible with the same fuel pumps The fuel pump that each vehicle will differ by the design of its own type, as well as engine requirements and performance specifications. For example, fuel pumps for high performance cars may have to deliver more than 340 liters per hour (LPH), while standard or stock pump only need around 100-255 LPH in order to meet daily driving demands. Compatibility is determined by fuel pressure, and type (gasoline or diesel) as well whether the car innately runs a returnless or return-style system.
Fuel system parameters are specific to each automotive manufacturer, and a pitfall may arise from using an incompatible pump that might create inconsistent fuel pressure. An incorrect pressure-rated pump can cause the engine to misfire or choke from fuel starvation, and in this case owners may see a 10-15% decrease of their vehicles' mpg rating. Automotive News recently brought our attention to a notice posted, also by the NHTSA on its site that stated over 200,0000 vehicles were recalled for fuel pump failures caused by using pumps not of those models in question.
A product needs no manual to operate — as Elon Musk once said, “Any Product that Needs a Manual is Broken. The same principle applies to fuel pumps-choosing one should be easy, and it must easily fit the needs of the vehicle without stress. Older vehicles with a carburetor usually need low-pressure mechanical pumps, but newer fuel-injected cars require more expensive jacked-up psi electric ones ranging between 40 and 70.
An often asked question like are fuel pumps universal on all cars? the answer is no. Every vehicle has different fuel delivery requirements, and if the wrong pump is installed it can cause expensive engine damage or a decrease in performance. It is imperative to verify the specifications of a vehicle, checking that its Fuel Pump meets with (the) same ideal flow rate and pressure requirements as well fitment.
