The carburetor is a way of life for some people. Could it be easier or cheaper? Maybe it’s all you know as far as getting fuel into their engine. Have you considered fuel injection and all the benefits that come from it?
Why electronic fuel injection? Fuel injection is much more efficient than a carburetor. Instead of relying on suction from intake air, fuel injection forces fuel through a small nozzle (your injectors) under high pressure and gives your engine the exact amount of fuel that it needs. There is no “falling on it’s face” with EFI as all of the fuel is pressurized and electronically controlled. Never again will you have to worry about stalling up an incline because your fuel swished to the wrong side of the bowl. You can decide the rate at which you wish your fuel to be delivered by changing fuel tables. If you’re a fan of MPG, fuel injection will give you noticeably improved fuel mileage.
Just like on your carb, when you press the gas, the throttle body blades open and the Throttle Position Sensor (TPS) sends it’s measurements up to the ECU where it then decides how much fuel needs to be sent to the injectors based on humidity, temperature changes and inclines which in turn, mixes with air and shoots into the cylinder, giving you the proper air-fuel ratio. Just think of how much work you’ve just saved yourself by letting a self tuning EFI system take control of your engine.
