Dumb Question..

[MSimpson]

This may be a dumb question but do the 1995 GMC Jimmy have a gaslight? When the fuel gets low in my truck I never see one. So I am not sure if mine is bad or it just doesn't have one..

No, pay attention to the fuel level.

If you know about what fuel economy you get (MPG), you can use the trip meter to help you tell when you're about to run out too. I have to do that with my 98 because the fuel gauge sits at full for 100 miles, then drops quickly to 1/4 and stays until I'm almost out of gas. I know when I get up near 300 miles on the tripmeter, I've used 13-15 gallons and it's filling time. The light comes on when I've got about 2 gallons or less left, and I don't like to get it that low in case I'm not near a gas station that I want to stop at (I only use top tier gas).

Also note, is is not a good idea to constantly run your tank to empty before filling it.

1/4 should be the lowest you allow it to plunge to unless in a situation where you cannot find a station.

The gas also acts as a cooling agent for the pump.

Also, condensation in the tank becomes a major factor when leaving the tank empty.

Condensation from what? -Water in the gas? Just curious

When the tank empties, it draws in air from the outside.

This outside air has moisture.

Very informative. I have never really worried about it in my truck but I have always worried about it in my sled. I am constantly pouring in isopropyl fuel additive to keep it from freezing up on a really cold night.

Easy way to stop it is to keep the tank above half at all times.

Plus your fuel pump will last longer.

added note, the pump uses gas as coolent as stated, if it gets warm, around all the cool stuff inside, thats how the moisture condences, like a cold drink on a hot summer day
