Smile D.I.Y. Replacing Fuel Filter

With fuel being the life line to your Honda engine, it's always a good idea to change your fuel filter at regular intervals. Here's a quick D.I.Y. article.

Approx. cost of fuel filter: $20
Time: 30 minutes max.

Required tools: 17mm spanner, 12mm ring spanner, 10mm socket attached to a ratchet and a screw driver.

Step 1. Disconnect the negative battery terminal.

Step 2. Locate your fuel filter. In this pic its behind the intake pipe.

Step 3. Remove the air intake pipe.

Step 4. Open the new fuel filter and look at the parts you got with it. (5 washers & fuel filter)

Step 5. Place suitable quantities of rags or something under the fuel filter, just in case any spillage may occur.

Step 6. Now you have to de-pressurise the fuel system. This is the service bolt.


Step 7. Hold on to the service bolt with the 12mm ring spanner & use the 17mm spanner to hold on to the banjo bolt. Loosen up the service bolt a bit then start turning the banjo bolt slowly. By doing this, it would de-pressurise the fuel system. This must be done slowly and the rags that you placed underneath the fuel filter would collect any spilled fuel that would have ejected.

Step 8. After loosening the fuel line connections and de-pressurising, Loosen up the bolt that holds in the fuel filter.

Step 9. Take a look at the new fuel filter it will have arrows on it. The one that is pointing outwards, you connect that to the hose that goes in to the fuel rail. The one pointing inwards, you connect that one to the hose that is coming from the firewall.

Step 10. Install the new washers.

Step 11. Installation is the reverse of removal, make sure to use new sealing washers at the banjo unions.

Step 12
.Remove the rags and flick the car to the 'ON' position a couple time to have the fuel fill up the new fuel filter and inspect for any leakages.

they told my dad the same thing about his '01. It's probably in the tank part of the fuel pump unit.

Good post Rob. I just had a problem with this fuel filter on my winter beater (Nissan Sentra). I had changed the filter last year. Well about 2 weeks ago, the car was cranking and i could hear the fuel pump working but it just wouldnt start. I checked for spark and there was, injectors where working, battery was fine and alternator, and i changed the cap and rotor just to be sure and still no luck. My brother tells me its the fuel filter but i told him its new with about 10-15000kms. So i go get a new filter and the car starts and is running smoother than before.

I dont know how many of you do this but dont let it run close to empty in your gas tanks. As your gas level gets lower, particulate matter will become more concentrated. Also, as the gas level gets lower, the intake will suck in only gas that is near the bottom of the tank, and therefore any gunk near the bottom can clog your filter.

Correct. On most cars nowadays, there is no external filter. One more way to cut down manufacturing costs!
