How often does the fuel filter needs to be changed? My dad's 1988 honda civic DX sedan is eating up gas like crazy. I changed new spark plugs, air filter, give it regular oil change, etc. The only thing I haven't touched are the o2 sensor(s?) and the fuel filter, particularly because I don't know where they are located at.

Anyways, How hard is it to replace them and will they make some differences in the mpg? I think they are still stock filter and sensors. lol! at least it hasn't been changed in the past 5 years that i'm aware of.

Well working for ford we say replace the fuel filter every 30,000 miles but we strongly recomend it every 15,000.

It will def. eat up your gas and can cause driveability problems later down the road.

Your 02 sensor for that car is on the exhaust manifold right underneatch the heatshield looking for one wire coming off the sensor itself.

what about the fuel filter? where is that located at? thanks!

Its on the firewall to the left when your looking at the engine, its a black cansitor(not the long one) the short one with two fuel lines going into it.

Go to a parts store and tell them the correct year/make/model and that you need a fuel filter, once you have one in your hands you can look at the engine and you'll realize what and where it is exactly.

The fuel lines can be a bitch to get off the first time Ive had better luck unbolting the fuel filter from its bracket and then hving better access to the stationary nut(underneath the fuel lines) its like a 16 or 17 mm wrench or use a crescent wrench put that on the filter to hold it then put the correct size wrench on the banjo bolt and turn it will eventually come. Be careful when removing the fuel lines from the filter there are two banjo bolt washers on each fuel line one for each side of the bolt to seal it. You should get new ones but just reuse the old ones, ive actually had new washers leak.

And dont put the lines on backwards its hard to do since each one only goes into it a certain way but I know some people cant even figure that out(not that you cant just speaking in general)

oh and to relieve fuel pressure first loosen the small 12 or 14 mm bolt on the fuel inlet hose, this will let out pressure in the lines so you can easily crack the fuel lines off and fuel wont spray all over you.

I recommend using OEM fuel filters. They also come with a full set of washers.

how much would an OEM filter cost, approximately?

Another way to relieve fuel pressure is to simply take off the gas cap.

That will help but it wont relieve pressure after the filter......and no matter what you'll still get some pressure its just gonna happen, its kinda messy but you get used to it, I change on average two fuel filters a day at work, gasoline in the mouth isnt as bad as you'd think.

But obviously the fumes ARE..

isn't there a fuel pressure relief valve/bolt on the fuel rail? The F22 engines have them so you probably have one too. You still have to place rags around the relief valve but at leaset you can control the flow. hope this helps

Kasper.

On d-series engines there is no pressure relieve valve I cant speak for much more honda's since I havent had enough experience with them.

The screw on the inlet fuel lines banjo bolt is your pressure relieve as well as taking off the gas cap.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Mrock &raquo;</TD></TR><TR><TD CLASS="quote">
