Fuel Filter Question

Postby Iurynnt » Tue Apr 09, 2019 11:55 pm

The old Dodge is turning 5 years old next month and the O.D. just rolled over 12.5k miles. I'm wondering about the life span of the fuel filter. I know you are to change them out every 15k, but I'm still using the original filter. Should I change out the 5 yr. old filter or is it not a problem to wait for another 2500 miles.
Also, any good air filters out there for the 6.7 Cummins https://bestarny.com/air-filters-for-6-7-cummins/ or should I stick with the OE filter. On my last Ford Diesel, I was told thatr the Ford filters were the way to go.

I’d say if it’s between: wondering if the extra year/ 2500 miles is ok to run, or changing it now for peace of mind, peace of mind is worth a lot to me :D

You’ve gone 5 years without having to worry about it, go ahead and change it and be worry free for another long while.

The Fleetguard FS1221 is another good filter for the first gen.

If you have a pressure gauge post-filter and see pressure never dropping off, would anybody still change the filter?

Depends on how much you drive it. If you drive it quite a bit I'd change it every 2-3 years anyways. I run mine maybe 4-5k a year and change filters about that often.

Filters filter better the longer they stay in service, right up until the point where they no longer flow enough.

Only if it's been years and I really have nothing better to do. Jiffy Lubes all across the country have dumpsters full of perfectly good filters behind them. But you need to worry more about the engine oil. And don't forget to filter the coolant, as well.
