i was just wondering what the size of the gas tank is for the '99-'02 silverado is. i made a bet with a friend that it is 24 gallons but in his manual it read that it was 26 gallons. since i have had my truck i have never filled up more than 24 gallons. anyways i was just wondering....

If I remember correctly, a short bed it 26 gal and a long bed is 34 gal I have put 25.4 gallons in my truck one time

 

ive run mine on the gas light for awhile before . most i ever got in it was 21 gallons . im starting to think its that big . everytime is around 20 or 21 . and a 5 gallon reserver is a lot in my book thats like 75 more miles or so

 

The size be stamped(molded) into the bottom of the tank. But it should be 26 gallons

 

I am with Badass, I have never put in more than 21 gallons in my truck.

 

a while back.. i put 26.024 gallons in my tank... hmmm and i know its the 26 gal tank, dont worry, i changed my fuel filter shortly after. Speaking of which.. whats the part number for the fuel filter, need to do that soon? its raining out today, dont really feel like getting underthere

 

I think it actually holds 26.5 I have put as much as 26.32 gallons in my truck. Of course the manual may not count the fill hose either, which I would imagine will hold at least half a gallon.

 

yea i hit 25 gallons almost everytime, but I have put in a little over 26 once or twice. It makes everyone so nervous when the fuel light comes on and I still drive another 50 miles, haha. The floatie thats in the tank must be pretty big. It just hits the bottom of the tank and thats what triggers the light. But the gas level in the tank probably sits in the middle of the floatie, so once it hits the bottom there can still be a considerable amout of gas in the tank. This is also why some fuel guages stay on full for a while.

 

ya i was wonder why before my gas milege sucked , because i was dividing by 26 gallons . now i go by how much i pumped in and to fill again and divide . im gettin 16 to 17 miles a gallon . i got like 13 towing a grand prix on a transport trailer from miami to ocala doing 75 to 85 crusing

 

Most I ever eeked into my tank was almost 26 gallons.
