Best Fuel Filter Buying Guide
While going through the market, you are going to find plenty of low-end models and many high-end ones. Low ends are usually cheap, and cheap does not always mean bad. You can get comparable performance out of the budget-friendly ones if you know what to look for before making a purchase.
We got your back in that regard too. The factors that you should look into before buying are:
Engines
Many gas-powered engines do not need any replacement of fuel purifiers as it has some kind of built-in mechanism. On the other hand, if your engine feeds on petrol and diesel, it will surely need replacing. Diesel fuels usually contain more contaminants and are thicker than the other types of fuel.
So, before you start looking for a purifier in the market, you should know the type of your engine.
Compatibility
Not all the cars that are out in the streets have the same motor. Different series of vehicles have a different model of engines. For that reason, there is no universal fuel purifying unit available for all the cars.
If you get a unit that is for the Duramax engine and you have a Dodge Ram 2012 model, you will not be able to fit it in your fuel line. That is why you should consider the compatibility of the unit first.
So, while you are looking into a fuel purifier, look for the official supported list first. If you can find your vehicle or the engine of your car in the listing, then you should be all good. But, if you can not find your four-wheeler in the listing, ask the supplier about the compatibility because many are cross-compatible with the engines.
If your supplier can not give you any information regarding the fitting, then you can compare the dimensions of your OEM unit with the one that you are planning to get. The dimensions should be on the packaging or the body of the purifier. If the numbers match, then you can get it without having to worry too much.
The Service Life
All the purifier units that you are going to find in the market will not be of the same material. Some might have a premium construction, while some manufacturers might skimp on the overall build-quality. The materials and the quality of the purification papers will dictate the life span of the unit.
You probably know by now that fuel purifiers need replacing after a period. The reason behind it is that the capacity of the purification papers and other units is quite limited. In that case, the better the quality of the purifier, the longer it is going to last.
By getting a decent quality unit, you will be eliminating the hassle of replacing the filters from time to time. That is why you should invest in a purifier that comes with good quality materials and papers.
Understanding the Purifier Units
Depending on the model of your car, the entire fuel purification system might have more than one unit. In that case, you should have a decent idea about the purifiers and what it does. Other than that, you will not be able to choose the one from the market that actually needs replacing.
Usually, most of the vehicles come with two separate purifiers. One of them is the water separator. It separates water and liquids of the same viscosity from the fuel. You can easily recognize it by looking at the unit because, in most cases, it will have a chrome exterior.
The other purifier that usually comes with the vehicles nowadays is the nanonet purifier unit. It screens out nanoparticles such as dust, debris, specs of rust and other particles from the fuel. Usually, you can see filter papers on the inside part of the canister, and it will have a brushed exterior on the outside.
Overall Installation Process
As you have stumbled upon this article, you are probably going to replace the fuel purifier by yourself. Going to the manufacturer for getting it replaced usually costs more, and you can save yourself some bucks by installing the unit by yourself.
In that case, you should look for the ones that are easier to install. Usually, replacing purifiers is a messy job because old ones are filled with gunk and all. But, after you take off the old one, most of the hassle is lifted. The part that you should consider is the process of fitting the new one.
So, go for the ones that do not require that much of tools and have no intricate threadings that you have to worry about.
Included Accessories
In case of fitting a purifier in your fuel line, you are going to require a few O-rings and rubber gaskets. If you want, you can reuse the previous ones, but they will not be that stiff and might even strip off while replacing. For that reason, you have to make sure that the unit you are purchasing comes with all the necessary accessories.
Other than rubber gaskets and O-rings, some units might also require proprietary sockets. Getting them from the market is a tedious process. Instead, just make sure that all the accessories that are needed come in the packaging.
Sets
Depending on the engine and the model of your car, the overall number of purifiers might be more than one. In that case, you might not have to replace all the units in the system at once.
Considering that scenario, you might think that it would be better only to get the one that requires replacing. But we would suggest you go for sets. As you know by now, fuel purifiers get gunked up over time and need replacing.
If you require to replace one of the units, the chances are that you might have to replace the rest of the units sometime soon.
To mitigate the hassle of shopping frequently, you should just invest in sets if your car has more than one purifying units.
Value
You are saving quite a few bucks just by replacing the units by yourself. But, if the ones that you are replacing with offer a good value proposition, the savings get doubled. For that reason, you should consider calculating the overall value of the purifiers that you are going to invest your money in.
We would recommend you to go for the ones that come with two-pack deals. Those usually offer more value than the individual ones.
But, that does not mean you can only get a good value proposition just by getting packs. OEM parts that sometimes go on sale are also the ones that offer an excellent value proposition. As car manufacturers usually install those, they are more reliable and can provide superior overall performance.
Manual
As you know by now, replacing the fuel purifiers from the line is a tedious job. It requires much more patience and effort. Proper guidance on how to replace the unit that you are getting will make the process much more comfortable. So make sure that the unit comes with some sort of manual.
Frequently Asked Questions
1. How often do you need to change the diesel fuel filter?
Compared to the other fuels, diesel has more contaminants in it. It’s thicker than other fuels and usually harder to purify properly. The purification task is a little bit taxing and will make the purifier clogged up relatively fast.
Depending on your overall driving style, we would recommend you to change the purifier after treading ten thousand to twenty-five thousand miles. This range of miles will also depend on the type of engine and your driving style.
You should also go through the manual of the car; generally, it states how frequent you should change the filter of the vehicle.
2. How often to change fuel filter?
In the case of gas engines, you will not have to worry about changing the purifier that often. Some even do not require any replacement at all. So, to get the exact information, we would suggest you go through the manual because most of them will have the period stated.
Besides that, for other engines, there is an easy trick to know whether your purifiers need replacement or not. Find an open road, and then go hard on the acceleration. If the car does not have any hiccups, then they are good, but if it does, you have to change the units.
3. How long does it take to change a fuel filter?
It depends entirely on the engine that your vehicle has. Depending on the model of the car, the purifying units might be in between or in the engine. There might be more than one purifier in the fuel line. So, the overall time that will be needed will depend on your car.
But, usually, the whole process will be a little time-consuming. Even though it might seem a bit tedious, you can certainly do it by yourself. Also, many units are shipping with step by step instructions that make the process easier.
4. What should I do before attempting to replace the fuel filters by myself?
There are a few things that you should consider before changing the fuel purification units by yourself. Firstly, you should know what type of vehicle you are working with, that is, to see the layout, the engine, and the location of the units.
Secondly, you have to wear protective gear. As fuels are flammable, anything can happen during the entire process. So, you should wear safety goggles and appropriate clothing before replacing the units.
Then you should have proper knowledge about the overall replacement process. If you start the process without knowing what to unthread and what to thread, then you will inevitably be stuck in the middle.
Lastly, while replacing, you are going to need a container for keeping the fuel that was in the old purifier unit. So, keep a large one around you before attempting the replacement.
5. What will happen if my fuel filters get clogged?
As fuel purifiers continuously screen out the impurities from the fuel, it gets clogged up after some amount of time. In the earlier stage of the clogging, you might not notice any change. But, you will see changes in the overall performance of the vehicle after using the same clogged up unit without replacement.
The overall fuel demand of the engine will increase during load. It will not be as efficient as it once was before the clogging. You will get comparatively less mileage. During hard accelerations, your engine will have performance hiccups. You will find it hard to start your vehicle. Lastly, you may even get engine misfires.
That is why you should replace the units as soon as you find out that they are clogged.
