Also, I have been putting in the anti-gel stuff recommended for very cold weather and hoping that is not screwing up my world too.

So this Stanadyne product, when you say additive, I know they don't have any type of "heat" like for gas, but what does this additive do? Do you change out your fuel filter frequently too?? OH... what if I drained my tank to hopefully get out any water in it as well, or would a separator installed be the remedy for that?? Thank you too sir for the input!

Steve
The fuel additive helps with lubrication, and anti-gel. Some use 2 cycle engine oil for the lubrication. I am not an authority on additives and fuel, I am passing on the information from my mechanic to help prolong the life of my injectors.

I change fuel, oil, and spin on tranny filters at 8,000-10,000 miles.

edigert,

What do you mean "spin on" tranny filters... are you talking about external filters you can change yourself? Sorry for all the questions...

No problem, that is what this place is for. Yep, the allisons have an external spin on filter. Very easy to change. There are vendors on here that have package deals for filters. I use madjackracing.com You can pick what type of filters you want, and they have fuel, oil, and tranny in a package.

The hydroboost (master cyl) runs off the power steering pump and if you don't keep the fluid changed or your working the thruck the powersteering runs hotter and my brakes when I got it real hot didn't even wanna work, so after burning through 1 hydroboost from running the wrong fluid and 5 pumps from heat, I put a 8x10 cooler on. Its a little excessive but I already had it laying in the garage so why not. Been good to go ever since.

For starters...

THANKS for all the feedback... got my Dodge sitting in my garage and now not sure what to do with it... trying to work with some car lots for an 05, but wanting to make sure our payment is not huge...

Thanks WVRigRat05... did not know that that system worked that way, LawnPro, we tried to get a NEW truck, but the payment was just out of this world... don't want to eat Top Ramen for the next 7 years...

Edigert brings up a subject that I have heard more than once not only on here, but since I have had these injector problems and that is "lubrication"... ; ) Fun word but do you all use or recommend Lucas Oil lubricant in your fuel? Aside from that, I am thinking, IF I keep this Dodge, of putting a water separator on it too... can't be too careful I guess in light of all the BS I have been going through with injectors... Any suggestions on what separator to use?

What makes me so dang mad, (I have other words for it...), is that after they installed new injectors, they did NOT put a new fuel filter in the truck... going to probably do that tomorrow... I just shake my head at the way they handle stuff, or not handle stuff at some of these dealers... which might be my biggest problem... dealers... Take care all and have a great day...

Buy an airdog lift pump if you get the chevy, they have 2- 2 micron filters one of which is a fuel/water sep. if you keep the dodge they already have a pump factory, I'd just put a filter housing on the frame rail and run a cat fuel/water seperator.

WVRigRat05,
Thanks for the response sir… questions though… when you say “pump factory”, not sure what you mean by that… (when I change out the fuel filter, I am pretty sure I turn a valve to drain the filter housing before I change the filter... not sure if that is what you mean... ) Also, the cat fuel/water separator… I have heard of a Caterpillar separator… is that what you are talking about on the frame? Thanks in advance!!

I second the airdog 2 lift pump so the water separator will help you out....if you are looking at 13's grab it....I have one and love it.....it has a stronger frame, bigger brakes, more hp and torque......it will pull your trailer any speed you wish.......

You're dodge has a factory fuel pump that the duramax does not have. The duramax relys solely on the cp3 injection pump to "suck" fuel from the tank to the pump then feed the injectors. This can be a problem if you run big tunes that require more fuel which the cp3 can not suck enough fuel to keep up so it drains the fuel rails and then IIRC puts the engine in limp mode (limits truck to 2000 rpms) and you'll have to clear the code with your programmer or scanner to get back out of it. It also takes the work off the cp3 since the lift pump pushes fuel to it so it wont have to suck as hard to get the fuel which is good considering this is a 900 dollar cp3
