I just did my fuel filter for the first time and the whoever changed it last left 2 orings on . Pretty simple job. it didnt want to fire right away though. I left key on and off 6 times before trying but it eventually fired up.

 

its normal after you change your filter, if it continues to do it then you have an issue. The lift pump does not turn on with the key you need to bump the starter in order to engage the lift pump.. and it still takes a lil wile for them to fire but its normal.

 

A fuel gauge is excellent for determining when fuel filters need to be changed. When my fuel pressure drops a few psi I change my filters. Filters actually filter better the older they get.

 

Filter better? I figured they would have a higher likelihood of damage and let more junk through.

 

This is a common misconception and the reason for dumpsters full of perfectly good filters at every quickie lube, car dealership and automotive service center of every type all over the world. At least the filter manufacturers are making money on it.

The only thing a used filter is "likely" to do is clog. The buildup of contaminants on the dirty side of the filter media increases their ability to trap ever finer particulates right up until that point. That is why a fuel pressure gauge (not the odometer) should be your main fuel filter monitoring tool. The primary filter on my 1st Gen has been in service over three years.

Oil filters are a different story.

 

I was on another site and a guy is changing his Cat filters every 3K and he was doing to to get the best filtration. We tried to explain how it worked, but........

 

I had a ford superduty with the 6.blow
And that one had a water seperator filter does the dodge filter do the same ??
The older the filter would get the more water it would pass right ????

 

That's why there is a drain on the bottom of the filter - to let the water out. Assuming there is any there to begin with. I've never seen more a few drops come out of my FW separator drains.

 

Ok coo
I'm new to dodge
Bought a 2006 3500 dually mega cab 4x4 with 135000 miles with a 6spd

About to do the first service to it what do u guys recommend in using and changing at this amount of miles
Sorry for the thread jack

 

At minimum...fuel filter and oil/filter. I don't care what people say the injectors on a cr are so picky I'm gonna change my fuel filter at least every 10k miles. Filters are cheaper than a $2500+ set of injectors. Use a Baldwin pf7977 for fuel and a Donaldson elf7349 for oil.
