Fuel filter replacement size

What is the part number and manufacturer of the filter that you bought? Most likely they "think" that this filter will fit the 5.9L and 6.7L or their book is wrong and giving you the part number of the other filter for the 6.7L. Or they simply looked it up wrong. This year was an odd year. You could still get the 5.9L in a 2500 but you could also get the 6.7L.

The Mopar part number for this is 5015581AB and that should be used as other aftermarket filters just don't filter as well.

Hopefully this helps. Let us know if you have other questions as well. Thanks

I looked it up directly from Mopar's site and I get the same number. Did you just purchase this truck? What is the last 8 of the VIN and I will look it up directly from you VIN but I imagine it will be the same.

Awesome. That was going to be the next step so you were on it. I was thinking someone may have altered the vehicle so it was a matter of inspecting the housing. I didn't expect that though.

One thing I will caution you with is if you have stuff in the filter housing then that stuff has most likely gone through the filter into the injectors and back to the tank. The nice thing is, you have a 5.9L which does not have all the emissions stuff on it that the new trucks do. However, if the injectors are damaged then they will over-fuel and can cause engine damage.

I would clean all that out and then run the truck for a few hours (doesn't have to be at one time) and then change the filter again and inspect the housing. With this fuel return system it will filter the entire tank of fuel in about a couple hours of run time. That means it pumps all the fuel to the rail and that which is not used is returned to the tank. So it all passes through the filter and if you have stuff in the filter now, then you have it in the tank. I would just want to check and make sure the new filter does not get breached due to all this stuff overwhelming it and you drive the next 15,000 miles before the next filter with a breached filter.

A breached filter is when it becomes clogged and the high pressure pump just pulls the fuel and debris through the filter. This debris passing through the injectors is what damages them and causing them to over fuel.

The last thing I would do is get a bottle of the CRC diesel injector cleaner and run it through. Then change the filter after a few hours of run time and then change it again after a couple tanks of fuel. If the last one is clean then you should be good to go.

Thanks
