Has anyone observed thier fuel gauge reading being off? When refueling between 1/4 and 1/8 of a tank indicated, I cant hit 17 gallons. I once ran it down until the low fuel warning came on. It took 17.6 gallons. I can appreciate a gauge that reads a little low but this is rediculous.

It's a 21 Gallon tank, so the light coming on at 17.6 isn't that big of a deal. You should not be running your tank that low any way, it's inviting gunk to get into your fuel line and at best, clog the filter.

The gauge is a bit strange though as 3/4 of a tank is not really 3/4 of a tank.

This is one other reason to spend the money on a ScanGauge. :)

As far as I remember since I started driving all my vehicles have traveled farther on the first half of the tank than the second. Seems to take forever to hit halfway then the next day the guage is at empty...

Exactly the same here: 60% of the millage on the first half and 40% on the second half...

Yeah, that will happen. Your gas mileage will get a bit better as the engine breaks in.

Mine though has got worse. Chalk it up to 500+ lbs of steel that wasn't there before. :)

Hey cheapo! Buy yourself a Scan gauge II and know exactly how much fuel is left! (adjustable) And know a lot of other things too! On the web! Search! My gauge was pretty much right on, But it reads different at times.

I'll second, don't be running it down to less than 1/4 or it will draw gunk. It's also not too good on the pump.

My scan gauge is within 1/10 of a gallon after I calibrated it. How could I go without one?

At ECXC my dash gauge was reading 1/2 then 1/4 then 1/8th, drove me nuts. Had it not been for the scan gauge I would have gotten very nervous. I just decided to go with that and it was right on. I had 2 gallons to spare at the end of the day.

If you ever really looked at how the gauges work, you will see how easily they can become hung up on the slider in the tank, both lever action and spiral do the same thing. Although spiral a lot less and more accurate. I don't know what one we have.

I am glad the warning light comes on early, vice late, I am not used to it coming on before 1/8 of a tank.

With 2700 miles on the odo, the mileage has remained unchanged, around 16 mpg. With 2700 miles on the odo, there better not be any gunk in the tank.

Too bad I didnt see that Scan Gauge before I bought my CarChip. I like the display, which CarChip doesnt have.

In this weather, You make the gunk, the less fuel in the tank, the more gunk you will be making. Ever gone to survival school? Know how to make water? Same principal. Seal your tank and let the temp change a few times, water in your tank. (Condensation) Mix that with all the varnish from the fuel = Gunk. The fuller the tank, the less the condensation and the formation of varnish form fuel.

I been to quite a few auto plants. Trust me, new don't mean anything there. Where do you think they piss when the Foreman won't let them stop the line? Not on the floor where they work.

Oh yea, the Nissan Maintenance Manual shows the fuel level transmitter to be a lever type. This is not enough of an issue to open that can of worms.

How was the installation on the Scan Guage, was it hard?
Where did you put it?

I believe and MC correct me if I am wrong. You just plug it into the Data port under the drivers dash. You will need to run the wires to your mounting location. No power wires needed.

That is right. I mounted mine in the space below the 4wd controls.

I noticed some of you talking about the fuel filter. I tried to locate it once before with no luck. Do we even have a fuel filter?
Page FL-5 of the Service manual... The fuel filter is part of the "Fuel level sensor, Fuel filter and Fuel pump assembly" inside the fuel tank...
