How To Remove A Rusted Fuel Filter


When your car needs its first quick refresh after years of idleing, you want to make sure everything is checked out before starting any repairs. One area that often gets overlooked is looking at the engine’s fuel system components.

As drivers, we don’t give much thought to how our cars get us from A to B, but their success depends on them functioning properly. The vehicle will not run if something goes wrong with the liquid fuel it contains.

Too many things can go wrong with the gasoline in your car including oxidation (it eats away at the chemical compound structure), water contamination, or microbial growth. All three are detrimental to engine performance and even cause damage to valves and other parts.

This article will focus on removing a rusty fuel filter for use in either an automotive service shop or your home. While some people refer to this as “changing the oil”, that term actually refers to changing the oil in your engine. Changing your car’s oil every 6-7 months is a good idea, but replacing a burnt up fuel element once in a while is just as important!

Removing a rusted fuel filter correctly will avoid damaging the engine. Fortunately, it is very easy to do! Read on to learn more about fuel filters, what could be going wrong, and how to remove yours safely.

Clean the filter

While it is not good for your engine to have an empty fuel filter, rusted filters are even worse! If you notice that there is no longer enough space in your engine’s bowl to fit the new filter, then it is time to replace it.

Make sure to buy a replacement fuel filter of the right size first before putting it into the car. You can usually tell if this is the case by looking at the back of the filter; make sure it does not look rusty or like it could crumble away.

Once you have found a suitable one, remove the old filter and put the new one in its place. Make sure to screw it in properly and check that it has no sticking threads. Once done, re-fill the tank with gasoline and try starting the vehicle up to see if it works!

Removing a fuel filter from a car is quite simple and should only take a few minutes per part. Hopefully, you will never need to do this step, but just in case you ever do, here are some tips.

The next step in how to remove a rusted out fuel filter is to make sure you have identified what type of fuel filter your vehicle has before trying to do anything else!

There are two main types of fuel filters for cars, canister-type filters and sock-style filters. I will go into more detail about which one goes where later in this article, but for now just be aware that there are different brands and models of each kind so check your car’s owner’s manual or talk to someone who knows about cars to help you identify yours!

Canister style fuel filters look like little cylinders with plastic pipings coming off them. These usually fit right over the top of the engine block. Sock style fuel filters are similar to ankle socks, only they attach to the intake pipe instead of being attached at the knee.

Replace the filter

After determining that your car is trying to tell you something, it’s time to look for the cause. If you noticed water coming out of the engine or if there was a smell, chances are good that the fuel filter has been ruined and needs to be replaced.

The fuel filter keeps excess particles from entering the engine. These can include dust from outside the vehicle, dried food bits, and even hair (ouch!). A bad fuel filter could also contribute to poor performance or damage to the engine.

There are two types of filters: canister and tank-to-tank. Canister filters work by containing debris in a container, while tank-to-tank filters use porous material to catch fluid residue. Both are easy to replace!

To save some money, don’t buy aftermarket replacements unless you have done this before and are certain they are made properly.

Check the engine for damage

In fact, if you feel confident doing so, you can use your hand to remove the filter! Simply take off as many of the plastic parts as possible and see what kind of fuel comes out.

If there is no clear liquid coming out, do not force it. That could cause more damage to the pump or the car. Instead, try using a tool to help pull the old filter out.

Since this article topic focused on how to easily remove a rusted out fuel filter, we will now talk about some helpful tools that can be used.

There are several different types of tools that can be used to scrape away the debris in the tank. Most people refer to these as fuel system tools. Some have even made their own versions to make them easier to find and use.

Run a fuel test

After you determine that there is no fluid in your engine, it is time to remove the old filter!

Most vehicles have a dipstick that removes the filters for you. You simply pull up on the filter and it will come out with help of gravity. If this does not work, use pliers or wire brushes to get it off. Do not force it, as this could damage the pump or needle valve.

After you have removed the filter, make sure to wash it and the area around it with soap and water. This will prevent dirt from getting stuck in the hole and causing clogging. Make sure to also check the oil level, as this may need replaced as well.

Now that you are confident in changing your own vehicle’s fuel filter, go ahead and do it yourself! Hopefully you learned some tips here today.

Make sure you do not attempt to remove your car’s fuel filter without first checking to see if there is any damage to the engine.
If possible, pull back the hood so that it does not block access to the engine!

If you feel able to take the top off the tank, doing this now is helpful as you can check the position of the dipstick more easily. If the stick comes up all the way out, then the filter was removed before and put back in incorrectly, which could cause water or gasoline to get into the engine.

Removing the old filter and replacing it correctly will help prevent fluid loss and potential engine damage.
