Your fuel filter is mounted on the firewall on the passenger side. Pretty easy to change yourself and you can buy a Fram fuel filter for around $20 at WalMart, etc. It would be a good preventive maintenance thing to do anyways, although it may not even be necessary.
Did they say why they thought it was needed?
Was that a Honda dealer or a place like Grease Monkey, etc?
For fuel injector service, I would just add a can of Chevron Techron Concentrate or a can of SeaFoam to your gas tank, fill it up and run it down to a couple of gallons before refueling again. Those cans are usually around $10 or less. That is also a good preventive maintenance move.
Happy to hear it is still running well. The 2000 was an excellent vehicle.
The NGK V-Power Copper spark plugs, ZFR6F-11 I believe, are cheap and seem to work well on that yr.
Don't forget to check the rotor, dist cap and wires if you start having any misfiring problems.
Brake fluid change and coolant change are also recommended
And, don't ignore changing the automatic transmission fluid, if you have an automatic tranny, using either Honda DW-1 or Valvoline Max\Life Dex\Merc atf or another synthetic compatible atf.
If you have an AWD, then the rear diffy fluid (Honda DP-2 fluid) may need to be done,
All of the above are very easy to do yourself, with the possible exception of the brake fluid flush (still pretty easy to do).
Whoops, almost forgot, get the valves adjusted or do it yourself.
Enjoy your 2000 CRV.

Thank you for all the great advice!! I'm not too bad at mechanical things for a woman but I do try to keep the bills in my pocket when I can. It sounds like the fuel filter is relatively easy to change so I will attempt that. I'm up-to-date with the differential and transmission fluids. I had a new radiator installed not too long ago so I think the fluid is still ok. I think valves and wires were also taken care of somewhere near the 100K mile mark when the timing belt was replaced. I have a good mechanic but I have to leave my car overnight and get rides both ways so it's sometimes difficult to arrange. Thanks again for the help!

 

I totally agree with Buffalo4. If you can stay away from those Grease Monkey places.

 

If you attempt to do the fuel filter yourself you want to look up on depressurizing the fuel system first. I believe you pull the fuse to the fuel pump and then crank the engine over a few times. If you don't then when you unhook the old filter it will spray gas everywhere.

 

If your car is running well, no issues, then paying for a "Fuel System Service" is a waste of money.

As Buffalo stated, you can try a fuel system cleaner, make sure you use it "as directed" on the bottle. The Chevron Techron I use sometimes says to put the bottle in just before a fill-up...drive around a few minutes, then fill the tank with fuel.

I think that an occasional "run to redline" also helps keep fuel injectors clean on their own. The increased duty-cycle of the injectors during full-throttle runs helps keep them clean.

An occasional use of Top-Tier Gasoline (certified to include extra detergents) is another good practice. I've noticed that GasBuddy.Com lkists Top-Tier stations now.


Regards the fuel filter: typical symptoms of a clogged filter would be missing or hesitation during high-demand situations such as full throttle (IE, pulling onto a freeway).
