I was under the impression that they were all 35 gallon tanks on the diesels. I know there is a 25 gallon tank on the gassers, but not certain about any others. My daughter has a 1998 12v QC/SB and it has the same size as my '96 CC/LB. Are you going by the fuel gauge for empty? Those gauges are notorious for going screwy..........

its been 5 years light comes on I fill up 25 gallons more or less every time How old is your daughter ? is she married ? :lol: I would love me a woman that drives a cummins so some do come with 35 gallon tanks then, a guy on eBay listed his truck with a 35 gallon tank and I thought he is just full of it

if i fill up when my fuel light comes on ther is still 5 to 7 gallons left in the tank. my 96 V10 had a 35 gallon tank. at 12 mpg it neede a 60m gallon tank:lmao:

Just look under it and measure how long the tank is. I will go measure mine and if they are the same then you have a 35 gallon tank. My light comes on at 5-7 gallons also. The gauge itself is not accurate at all. I mean it is close but when my gauge stays at F for 200 miles, flies down to half, stays there for 300 miles, then slowly goes to 1/4 then flies to E like a bat out of hell, it shows how accurate it is. The low fuel light is accurate though so I just go by that.

Long beds are 35 and short beds are 34. My fuel lights comes on and I can usually only get 26 maybe 27 gallons in. Im in the process of running it down right now to see how many it will hold. My lights been on for 30 miles ar so but I only have a little over 400 miles on the tank and at 17mpg with a 35 gallon tank I should get almost 600.

I get between 420 and 460 to a full tank before the light comes on

I know for certain my tank is 35 gallons. I have filled up at 34.5 gallons once. My light usually comes on at 700 miles.

I went another 20 mies and then filled up and almost got 27 gallons in. I forgot I pulled a trac hoe for a few miles and it cut my mileage down a little.

i have yet to take a long trip to burn a full tank of fuel..like interstate..cruise on..so back and fourth to work..which is 20 miles away one way and then get shut off and warm ups in the morning..the best i have gotten is 320 miles on a half of a tank...i don't think that is bad for an automatic truck..well what is in the sig..and just put the grid heater delete and ats arc flow on yesterday..so may improve alittle(and maybe alittle more when the new rv275's get installed).:thumbup2::woot:

Well I learned something today, i didn't even realize there is a light on mine!:lmao: I know my gauge isn't reading accurate but try not to let it go to low anyway. I usually fill up at half a tank and usually have about 400 miles on it, so i doubt there near that left in it.

Today I found out I have a smaller than usual tank I looked at a 2500 5.9l gasser for a second plow truck and it had a tank almost double the size of mine I had both trucks stand side by side and I crawled under the gasser to check for rust etc and I was shocked of the tank size :stuned:wish I had a bigger tank :cry:

There is a company advertising on tv that will sell a tank twice as large, the gasser might have one of those under it??? I have a 99 qcsb and have a 34 gallon tank, which is plenty as I am never more than 600 miles away from a diesel pump. As for a larger tank, it only means more money to fill it up, although if you find a cheap price it might be worth it, but in that case I can just throw my 100 gallon tank in the bed and get all the fuel I need for a while. As for you daughter, I am not sure if she could put up with me, as I too am very sarcastic!

According to FSM specs for 2001 its 34 gallons for short wheel based and 35 gallons for long wheel base.

According to my FSMs ('94-'96 and '98) there were two tanks available. One is 35 gallons and the other is 26 gallons. I never knew that until I looked it up.:cool:

most ive ever put in mine when the light comes on is 26 i recently drove it down to arkansas all highway driving 60-65 mph and without correcting for tire size ( dont know how to) i got 316 miles out of 3/4 of a tank which was about 16 mpg's with my edge on 1x1!!!! i guess this is ok for a truck with 315 tires and 4.10's with a NV4500???!!!!:shrug:

Umm... learn curve for Edge Comp boxes... The quick answer is 1x1 is going to give you the least boost of MPG over 5x5 will give you the most...

You main level is how much timing curve you going to get with the maximum amount of fuel. So for the most timing you need the main level set to 5. So 1 being the least amount of timing and 5 being the most.

Now as for sub level... Sublevel is how fast you get to full fuel and timing in relationship to boost.

1. 33% of stock fuel and timing till 20 PSI

2. 50% of stock fuel and timing till 15 PSI

3. 67% of stock fuel and timing till 10 PSI

4. Some extra fuel and timing at 0 PSI

5. Full fuel and timing at 0 PSI

So if you looking for the most amount of timing keep it on 5x5 and use a light foot... Another tip is as the boost rises above 5 PSI the timing starts to retard. This princepal is from the autoignition temperature.

http://en.wikipedia.org/wiki/Autoignition_temperature

The autoignition temperature or kindling point of a substance is the lowest temperature at which it will spontaneously ignite in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion. The temperature at which a chemical will ignite decreases as the pressure increases (Boost pressure) or oxygen concentration increases. It is usually applied to a combustible fuel mixture.

So to keep timing correct the VP44 is going to retard slighly to keep from over advancing the timing...

post-2-138698173236_thumb.png

Take notice the timing it more advanced at low boost pressures compared to high boost. So running the Edge Comp on 5x5 with a light foot and low boost pressures you can increase that stock table higher... :cool:
