Quality fuel injector cleaners that use polyether amine chemistry do clean the fuel lines. The additive also needs to be properly sprayed through the fuel system.Know More
Fuel injectors work by pumping a pressurized amount of fuel into a small opening. Overtime these injectors build up carbon deposits; these deposits disrupt the flow of fuel to and from the engine.
Two Common Types of Additives Used in Fuel Injector Cleaners
Polybutene Amine (PBA)
PBA is commonly used as an additive in gasoline mixtures. This additive, when used with the recommended dosages, prevent build-up from inside the system. Unfortunately, over-using PBA additives will contribute to carbon deposits inside the engines chambers.
Polyether Amine (PEA)
PEA is a higher grade fuel additive that helps maintain combustion chambers. PEA is commonly used in dealership rated fuel system cleaning services.Learn more about Car Parts & Maintenance
Most fuel lines can be repaired for no less than $120 dollars. If the fuel line has to be replaced entirely, the cost depends greatly on whether the mechanic has to drop the car's fuel tank to replace the lines. If so, this can add an additional $400 or $500.Full Answer >
To change the fuel filter on a Kia Sportage, disconnect the fuel lines, and replace the old filter with a new filter. You need a floor jack, jack stands, open-end wrenches and a new filter.Full Answer >
Fuel additives designed to clean fuel injectors, carburetors, ports and intake valves do work, according to RepairPal, particularly if they have polybutene amine, or PBA, as part of their chemical makeup. However, those with polyether amine, or PEA, chemistry deliver the same benefits without causing deposits in the combustion chamber.Full Answer >
Fuel injector issues can become apparent with many different symptoms including problems with the car starting, idling problems, a failed emissions test, generally poor car performance and an inability to reach high revolutions per minute, or RPMs. Two major problems exist with the fuel injector. There are bad, faulty, clogged and leaking fuel injectors, which generally cause a decrease in performance, and a leaking fuel injector, which can cause fuel odors within the vehicle as well as poor performance.Full Answer >
