Replacing The Fuel Filter In Your 1990 Honda Crx

If you're looking to replace the fuel filter on your 1990 Honda CRX, you're in the right place. This is a maintenance item that should be replaced every 40,000-80,000 miles, so it's important to know how to do it safely. The process is fairly straightforward and can be done at home by an intermediate DIYer. You'll need to relieve any pressure in the tank by opening the gas cap, then remove the bolts on the top of the filter, and the bolt holding the filter strap in place. Dispose of the old filter properly, then install the new filter with new fuel line washers. Finally, check for leaks once everything is tightened up. The average cost for a Honda CRX fuel filter replacement is between $89 and $109, but parts and labour can vary depending on your location.

Prepare tools and safety measures

To prepare for replacing the fuel filter in your 1990 Honda CRX, you will need to gather the necessary tools and safety equipment. Here is a list of the tools you will need:

• A new fuel filter: Ensure that you purchase a compatible fuel filter for your 1990 Honda CRX. You can find these at auto parts stores or online.
• Wrenches: You will need various sizes of wrenches, including 10mm, 12mm, and 17mm. An oil filter wrench can also be useful to hold the filter in place.
• Socket and ratchet: A socket and ratchet can help with removing tight bolts.
• Shop rags or towels: These are important to have on hand to catch any fuel that spills or drips during the process.
• New washers: It is recommended to replace the washers on the fuel lines when installing a new fuel filter.
• Thread sealant: This is optional but can help with sealing the connections.

Now, let's discuss the safety measures:

• Work in a well-ventilated area: It is important to have adequate ventilation when working with fuel to avoid inhaling fumes.
• Eye protection: Wear safety goggles or glasses to protect your eyes from any fuel splashes or debris.
• Gloves: Wear gloves to protect your hands and avoid direct contact with fuel.
• Fire extinguisher: Keep a fire extinguisher nearby in case of any accidents or fuel spills.
• No smoking: It is crucial to avoid smoking or any open flames during the process to prevent fire hazards.
• Remove ignition sources: Disconnect the negative battery cable to remove an ignition source and prevent accidental engine starts.
• Relieve fuel pressure: Before starting, open the gas cap to relieve any pressure in the tank. You can also disconnect the fuel pump fuse and crank the engine to reduce fuel pressure.

By gathering these tools and adhering to the safety measures, you will be well-prepared to replace the fuel filter in your 1990 Honda CRX. Remember to work carefully and follow the instructions provided by the manufacturer or a trusted repair guide.

Remove bolts and the fuel filter clamp

To remove the bolts and the fuel filter clamp of your 1990 Honda CRX, you will need to follow these steps:

Firstly, locate the fuel filter on the passenger side of the engine compartment. Before you begin, open the gas tank filler cap to relieve any pressure in the system and observe all fuel-handling precautions. Wrap a shop towel around the fittings to catch any fuel that may spill.

Now, you can start to loosen the bolts. Using a proper wrench, slowly loosen the two banjo bolts from the fuel lines. You may need to hold the filter in place with a wrench or screwdriver to prevent it from spinning while you loosen these bolts. Place the wrench or screwdriver in the space underneath the banjo bolt or in between the two bungs on top of the filter.

Next, remove the bolt that holds the fuel filter clamp in place. This bolt will be located on the firewall, connecting the fuel filter bracket to the firewall bracket. Once this bolt is removed, you can take off the clamp and carefully lift the old fuel filter out of the vehicle. Remember to dispose of the old filter properly, as it will be full of fuel.

It is crucial to replace all of the fuel line banjo bolt washers every time you loosen the bolts. If these washers are not replaced, the fuel lines will leak pressurized fuel, creating a risk of fire or explosion.

Remove the old filter

To remove the old fuel filter from your 1990 Honda CRX, first open the gas cap to relieve any pressure in the tank. Place a rag underneath the filter to catch any escaping fuel.

Next, remove the two bolts on the top of the filter. You may need to hold the filter in place with a wrench to do this. If your CRX has a small bolt to relieve fuel pressure, loosen this first, then remove the remaining two bolts. If not, just remove the two bolts.

Now, remove the bolt that holds the filter strap in place, and take out the filter. The old filter will be full of fuel, so dispose of it properly. You can funnel the fuel back into the tank or put it in your lawnmower.

Finally, install the new filter with new fuel line washers.

Install the new filter

Now that you have removed the old fuel filter, you can install the new one.

First, wrap a shop towel around the fittings and slowly loosen the fuel line fittings using a proper wrench. Attach the new filter to the fuel lines, using new washers, and tighten the bolts to 20 ft. lbs. (27 Nm).

Next, tighten the clamp mounting bolt to 7 ft. lbs. (10 Nm). Ensure that the filter is securely in position.

Finally, start the vehicle and check for any leaks. Put the gas cap back on and turn the ignition key to the ON position. Wait for the fuel pump to prime, and check again for any leaks.

Check for leaks

Once you've replaced the fuel filter in your 1990 Honda CRX, it's important to check for leaks. Here's a detailed guide:

First, make sure you have tightened all the connections and fittings securely. This includes the fuel line banjo bolts and the clamp mounting bolt. It is recommended to tighten the clamp mounting bolt to 7 ft-lbs (10 Nm) and the banjo bolts to 20 ft-lbs (27 Nm).

Next, start the engine of your Honda CRX. With the engine running, carefully inspect all the connections and fittings that you disturbed during the fuel filter replacement. Look for any signs of fuel dripping or leaking from these areas. Pay close attention to the banjo bolts and the clamp mounting bolt, as these are critical for maintaining a secure and leak-free connection.

If you notice any leaks, immediately shut off the engine and address the issue. Leaking fuel can be dangerous and can lead to fires or explosions. Ensure that you replace the fuel line banjo bolt washers every time you loosen or tighten these bolts, as worn washers can cause leaks.

Additionally, check the area around the fuel filter and lines for any signs of fuel spray or misting. This could indicate a leak or improper connection. If you notice any fuel spray, carefully retighten the connections and inspect for damage to the fuel lines or fittings.

After you've confirmed that there are no leaks, let the engine run for a few minutes to build up pressure in the fuel system. Then, shut off the engine and inspect the fuel filter and lines once more. This step is important because sometimes leaks may not be apparent until the system is pressurized.

Finally, if you have access to a vehicle lift, raise the car and inspect the underside for any signs of fuel leaks. This step ensures that you haven't missed any leaks that may be hidden from view.

Remember, working with fuel can be dangerous, so take your time, follow safety precautions, and address any leaks promptly.
