i have 2005 dodge ram 5.7 hemi quad cab 4x4, i but it with 112,000 i have 133,000 approximately now, i but it from a dealer so i'm not sure if the fuel filter was ever changed, do any of you guys think it should be something that should be done? if so, any recommendations on which ones, or anything, is it a pain in the ***? because its in the tank right?

Also anyone have an idea about maybe the pump too?

thanks a lot guys/gals every time i post on here someone really takes their time to help out really appreciate it, ok thanks a lot

 

The fuel pump and fuel filter are all one unit. The only reason to change the filter is when the pump fails.

 

Correct. I have pics of the sock filter on the pump in my gallery somewhere. I've never really known or met anyone that really needed to replace it

 

really so the filter doesn't really get "clogged" or needs to be changed like an oil filter or air filter?

 

Your fuels are filtered through the manufacturing process many times. They are filtered from the truck unloading them into the underground tanks at the gas station. They are filtered again just before the nozzle as it goes into your ride. So if you have anything that is in your tank other than fuel, you better find a new girl or stop messing with someone else's and buy a locking cap

 

thats a good one i actually did chuckle to myself at the end...i don't have a problem with any clogging or hesitation, or (crazy psycho people adding nice stuff to the tank) i just never had a car long enough to rack up over 100,000 miles so i thought that it was something on the "to do" list for when a vehicle gets a little bit of mileage on it, but thanks for the info, i appreciate it

 

The 3rd Gen setup is probably similar to the 2nd Gen, but "never say never" that the filters can't get clogged. The 2nd Gen fuel pumps have a screen, referred to as a "sock" at the bottom for the initial pickup; then a filter in the main housing, and finally, the pressure regulator acts like a third stage filter. When I rebuilt my 2nd Gen's engine I discovered three of the injectors were plugged on the inlet side and that there was a buildup of gunk in the fuel rail. I sent the pressure regulator to a friend who worked at the factory that (then) made the Chrysler pressure regulators so the lab techs could analyze a sample from real world use. The cut open pressure regulator looked like it was full of coffee grounds from captured gunk and sediment. Amazingly, the pressure regulator was still within tolerance.

The fuel tank was almost empty and I noticed, upon inspection, that it had a layer of gunk and crud along the bottom. I washed out the tank before installing the new fuel pump assy.

The gunk and sediment will enter the tank from dirt and dust that find their way to fuel station nozzles and their cradles. It takes a long time for little bits to find their way to the tank, not to mention if someone is filling a tank from a gas can and didn't take the time to wipe the nozzle inside and out.

Overall, a fuel pump & filter assy will last upward of 200K miles without any issues.

 

hey gary...or anyone actually, you brought up, fuel rails, i see that bbk and some other companies offer new fuel rails, mine looks beat to hell, all rusty and stuff, do you think that is something that is worth looking into getting? or just leave stuff alone, if it aint broke don't fix it, i just don't know if i'm losing any pressure or if the rails would help with performance in any way plus, is it a project that is very detailed? is there a way to see if i would need a new set of the rails, and how would i check injector flow, and sorry for all these questions, but you guys are so as hell pretty smart and witty, over all just really knowledgable thanks a lot guys

 

I wouldn't worry about replacing the fuel rail unless there's a need to dive in for major engine repair work. A rusty exterior is not indicative of the condition of the rail's interior.

Some people like to clean up the fuel rail and wrap it using a special insulation wrap that keeps the temperature of the fuel cooler during deliver. Apparently, that does increase the engine's efficiency a bit.
