I can't tell ya how much is left in your tank but in my 92 it's 5 gal.
Hey take that thing to a Cummins shop. I bet they can figure it out in no time. It's at least worth a try. Had a friend of mine go through power problems in a new truck and when the day was done they gave him a new truck. Cummins said they could probably have fixed the problem in a couple of hours.

good luck

 

neveragain -
115.4 Liters = 30.49 gallons
115.6 Liters = 30.54 gallons

Divide by 3.785

 

Just filled up 29.4 gallons 500 miles = 17 MPG. All city driving.

 

i can hit 700 miles before the low fuel light comes on, on my last tank it was at 819.2 miles when it dinged at me, i made it too 889.6 miles before filling.

 

ramtd02 - How many gallons did you squeeze in there?

 

anywhere from 39-42, it takes me an extra 10 minutes or so. It works out too an average of 22 mpg +or- 1.

 

How do you know those mileage figures are accurate? Did you work from the odometer or from a known actual distance? Did you change anything such as the size of the tires? (Yes, I know you said it was stock)

 

Now you guys got me thinking I only get about 550 KM City Driving before my fuel light comes on thats like 342 miles doesn't sound very good thats with 410 gears and a 29 inch tall tire thats on 27 US gals

 

See if ya can get some 33's one there next tire replacement. They will bring that 410 down a bit and maybe a bit better milage.

 

When I retire it will be a true 35in tall tire with a lift

 

Ok guys & girls. To boil this thread down, what did you do that had the biggest effect on increased mileage.

 

I think the thing that helped the most was the pump mods.

 

I figure I have done just about everything I can think of to boost my mileage. The exception is probably IF a box like the Smarty TRUELY can help, but since I have kicked out the money for the Ramifier, am happy with it, I am not inclined to purchase another unit unless I KNOW there will be a substantial payback, plus it is my understanding that there is not one for the CR engines yet.
The fact that it is an automatic, 3rd. Gen, and 4X4 is all working against me. I am full synthetic, did the tone ring mod, should be pretty well broken in, I can tell when I am sincerely trying. To answer your question, the farthest I remember going on one tank was 640 miles before stopping. On my most serious effort, I truely believe I could have gone 700 miles (34 gal. tank with the vent kit mod), but it was pretty painful to be that good for 306 miles (needle was straight on top of the 3/4 mark), and now that I hear that low fuel levels can kill pumps, I probably will give up on my dream of seeing 700 miles before pulling in, unless I do it in stints or something. which brings up a question: Any guesses on how fast the fuel heats up from being pumped? Let's say it is a 70 deg. F day, I am driving steady on the hwy, and there are 5 gal. left in the tank?

 

Ramtd02.......
I notice you are in Canada. Are you POSITIVE we are talking U.S Gallons and MILES? Something doesn't sound right for a 4X4 06.
Also, I thought the Longbox tank was rated at 35 U.S Gallons. Even allowing for a couple more to fill the neck, if you run it bone-dry, you still come up with 37. The fact that it takes 10 minutes tells me (along with your statement that the truck is stock) that you have not done the fuel breather mod. What am I missing?

 

hey, first post, i just thiught i would chime in on the milage thing. 96 2wd, auto trans, i usually drive it like a bat out of hell, fill up once a week at around 450 miles on trip odometer. i average 18 miles a gallon or better, up to 22 mpg at slow speeds. don't say i don't know how to figure fuel milage, as i am an over the road truck driver, and i keep a close eye on fuel consumption, so i am assured my fuel bonus.
