Fuel filter: how often to replace?

[jeremyc74]

Um dealers are blaming poor fuel for injector damage left and right. And hpfp failure as well. It's a very common excuse for them to weasel out of a $10,000 repair for a complete fuel system replacement. It's even more prevalent in the diesel engines.

If you let them get away with that you're crazy. For them to deny warranty for something like that they have to prove it was the fuel.

Can you post an example? BMW blamed fuel for HPFP failures on the N54 engines, but they warrantied every single one of them, and then extended the warranty to 110k miles out of fear of EPA backlash.

The emissions system warranty isn't the same as the vehicle manufacturer's warranty. The coverage on that stuff is mandated by the EPA regardless of the standard warranty.

Still, gas stations still keep gas in metal underground tanks and those still corrode and get old and you never know when the fill-up truck left fifteen minutes before you got there and stirred it all up. I like having one, and if I have one, I'm going to change it. People have to change injectors all the time on these trucks. If it saves me one injector change, a new filter is worth it.

The EPA forced the stations to get rid of all the steal tanks. Everything now is double walled, with a corrosion resistant inner tank and leak detection between the inner and outer.

Most of the steal tanks had to be replaced in the late '90s. That's probably what allowed the vehicle manufacturers to drop the fuel filters completely.

I would but I'm to lazy to dig up my old logins. If you want just start searching Google. It's very common.
