Bad Fuel Reading - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lts70 · 10-31-2007, 08:03 PM

When I fill my blazer tank up on my truck the fuel gauge reads ¼ over full capacity. As I drive it around it seems to stay at the ¼ over full to full mark for quite awhile then quickly drops from there. As it works below full the needle sometimes gets a bit jumpy but not always. I would like to know how I can get it to read more accurately. All it is really good for right now is telling me it is full or almost empty. I have the tank bolted directly to the frame so I don’t know how a bad ground could be the problem even though it is the first thing that comes to mind. Thanks.
