RPO Codes beginning with the letter N

 

NA4

NP1

NP5

NT9

 

Anybody know what size can I have? New to me truck (04 2500 HD 6.0) gives a low fuel light and only holds 20 Gallons.

Otherwise the DIC says you got very few miles to empty.

 

My thoughts are that a 22 gallon can is awful small for a 6.0 HD truck. But this seems consistent with the fuel gauge and the DIC.

 

Am I gonna have to carry a 5 gallon can and pull a Cosmo Kramer just to see how low I can go?

NA4 - 8600 emissions

NP1 - Electric transfer case

NP5 - steering leather wrapped

NT9 - ??

 

Look for N23 - 22 gallon tank, or N03 - 36 gallon tank

 

Also, you can run your Vin thru this website and it should tell you too.

assuming your truck is a standard bed(6.5'), then your fuel capacity is 26gal, long bed is 34gal....

 

there have been isues with the fuel sending unit showing less fuel in the tank than was actually there.....

 

yes, the tanks are on the small side to be sure...

That's what I like about this site!

 

There is no RPO that describes my fuel tank. All specs alldata etc says it oughter be 26 Gallons. (Yes I am Crew Cab Short bed).

 

I guess Cosmo Kramer here I come. I am going to drive around with my low fuel light on until it quits.

 

Yeah I know I am gonna be sorry too... gonna suck up all the water and goo in the can and maybe even overheat the fuel pump.

 

Hopefully I will just run out of gas though.

Do what I did; I went to Transfer Flow and had them take out that 26 gal. tank and had them put in a 45 gal. tank. I'm quite the happy camper now. I can quite comfortably go over 600 miles on a tank.

Be prepared to replace your fuel pump

+1 Why do you need to run it till it quits? Thats just asking to burn a fuel pump up.

My 08 CC dually is the same. When the dic stops showing miles to empty it only takes 24-25 gal. to fill.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
