Default Fuel Filter

A dealership is telling me that they suggest that you change the fuel filter out on the car every 15k miles?Best Plugs? Best Wires?

I can see for a modded F/I car. But for a basically stock N/A car, I would do it every 25-30k, depending where you live.

You'll need a 3/8 and 5/8 fuel line plastic tool(come in a package of different sizes) and probably a 18mm opened ended wrench. Might want to let pressure out of the schrader valve on a cold engine first.

Every 15,000 is way overkill in my opinion to replace a fuel filter. Especially one that's the size of the ones in the CTS-V, a Lightning and a Mustang Cobra. I replaced my filter in the Cobra 2X while racking up 113,000 miles. No loss in performance either. Out of curiosity, the Cadillac dealer quoted me $91 to do mine which includes the filter. Maybe when mine hits 35,000 miles I'll have them do it. I don't like messing with the gasoline.

naa....just pull the fuel pump relay...start or attempt to start the car and your golden....

either way I changed mine out at 20k and it was pretty bad...lots of black **** and couldn't blow through anywhere near as good as the new one....every 15k does seem a little excessive though.

Very simple install. Took 30 minutes tops on a lift so maybe 45min-1hr on your back.

I have a 05 c6 vette and it has a filter in the gas tank , just wondering does any of the ctsv's have the same setup and if so when do you change out the intank fuel filter?

Most the time you change the intank filter when the fuel pump takes a dump. Never heard of anyone changing the sock on the pump unless the entire pump was changed.
