Which item is not a part of the fuel system

Make sure you follow your manufacturers recommendations as to when you should change the fuel filter. This information should be in your owners manual. Symptoms include sputtering at high speeds or engine not starting at all.

Always check the ignition system first, if that's ok then the next suspect is the fuel filter. Next most common problem is the fuel pump failing. Most modern electric fuel pumps can be heard when you turn the key on.

If you don't hear the pump running and your car will not start, it could be your fuel pump. The first thing a mechanic will check is the relay which sends power to the pump. If this is operating correctly then the pump will have to be replaced.

Last but not least is dirty injectors. While the fuel filter does a good job of filtering the fuel, it's not perfect. Over time deposits and tiny particles lodge themselves in the injectors. This can clog an injector and prevent it from delivering the fuel the engine needs. It can also cause an injector to stick open and send too much fuel into the engine. A regular addition of fuel system cleaner like STP Injector Cleaner, or Techtron fuel system cleaner can help keep your injectors clean.

Most gas stations, department stores and all automotive parts stores will have a good cleaner available. Add it to your empty tank right before you fill up and it will clean as you drive. I recommend doing this every 3 months to keep your injectors performing like new. Mechanics also offer a cleaning service where they actually disconnect the fuel line and flush cleaner through the engine.

This is only necessary when you let your injectors get to a point where they can not be cleaned by a store-bought product. Regular use of a good in-tank cleaner will keep you from having to pay for this service. Believe it, or not, it can make a difference. Always buy from a well know national brand service station.

Gas stations which are not affiliated with one brand of gas tend to get whatever is left at the end of the day from the delivery truck. One day them might get Texaco, and Exxon another. Also water mixed with gas will cause problems with your engine. The engine will not run right, plus the water will promote rust in the fuel system. I have experienced this when I purchased gas at some no-name gas stations. The same can be said for any major component in your vehicle.

Having your fuel system serviced regularly can help prevent the inconvenience of a failed fuel pump, ensures optimal fuel efficiency, and the very best performance intended for your vehicle. At Sun Devil Auto, we know the fuel system and just what it needs to continue operating for peak performance. Replacing your fuel filter every 60, miles as well as a fuel system cleaning every 30, miles is one of the best ways to ensure your vehicle continues processing and burning fuel properly.

The pump sends fuel from the gas tank to the engine.

Some vehicles are equipped with multiple gas tanks and even multiple fuel pumps. Multiple fuel pumps are ideal for ensuring the vehicle always has access to fuel no matter the terrain that the vehicle is traveling on. For example, if a vehicle is making a sharp turn or traveling on a steep incline and gravity forces fuel away from one fuel pump, it guarantees that at least one of the pumps has access to fuel.

The pump forces fuel through the fuel lines that deliver fuel from the tank to the engine for combustion. The fuel filter is the next stop for gasoline before it reaches your engine. It is imperative that the fuel that enters the engine be uncontaminated and free from dirt or particulates. To prevent any debris from entering the engine, the fuel filter will aid in removing dirt or debris.

A clogged or dirty fuel filter is unable to trap harmful particulates from entering your engine and cause all sorts of damage. In addition to keeping solid particles out of the fuel supply and injection equipment, water in fuel must also be prevented from entering critical fuel injection system components.

Free water can damage fuel lubricated components in the fuel injection system. Water can also freeze in cold temperature conditions and ice may block small fuel injection system passages thus cutting off the fuel supply to the rest of the fuel injection system. Water can be removed from the fuel using two common approaches.

The incoming fuel can be subject to centrifugal forces that separates the denser water from the fuel. Much better removal efficiencies can be achieved with a filter media that separates water. Figure 3 shows a filter using a combination of media-type and centrifugal approaches. Different water separation media operate under different principles. Hydrophobic barrier media , such as silicone treated cellulose, rejects water and causes it to bead up on the upstream surface.

As the beads become larger, they run down the face of the element into a cup under the force of gravity. Hydrophilic depth coalescing media , such as glass micro-fibre, has a high affinity for water. The water in the fuel associates with the glass fibres and over time as more water enters from the upstream side, massive droplets are formed. The water moves through the filter with the fuel and on the downstream side, falls out of the fuel flow into a collection cup.

Increased use of surface active fuel additives and fuel components such as biodiesel have rendered conventional separating media less effective and filter manufacturers have needed to develop new approaches such as composite media and ultra-high surface area coalescing media [] [] []. Fuel filters can also contain additional features such as fuel heaters, thermal diverter valves, de-aerators, water-in-fuel sensors, filter change indicators.

A fuel preheater helps minimize the accumulation of wax crystals that can form in the fuel as it cools to low temperatures. Common heating methods use electric heaters, engine coolant or recirculated fuel. Two approaches that use warm return fuel to heat the incoming fuel are shown in Figure 1.

Fuel overflow and leak-off fuel returning to the tank also carries air and fuel vapor. The presence of gaseous substances in the fuel can cause difficulties in starting as well as normal engine operation in high temperature environments. Therefore, bleeder valves and de-aerators are used to rid the fuel supply of vapors and air to ensure trouble-free engine operation.
