2000 GMC SIERRA 5.3 low fuel light after fill up
I have owned my truck for about 8 years and it has been this way since I bought it. After I have burned off a few gallons it seems to read an accurate fuel level. I have seen many posts about this problem but would like some people that have had this and had it fixed to explain what is wrong and est cost to fix.

I'm curious. Doesn't the fuel pump only feed fuel into the line and engine ? Does it also measure the amount of fuel in the tank or wouldn't that be a fuel level gauge sensor ? Just trying to narrow it down. I'm sure you know what you're talking about but trying to get multiple opinions on this. Thank you for your information .

I known of some that removed the assy , then cleaned it put it back in to work great for a time then only to act up again.
I use techron fuel treatment with a few ounces of marvel mystery oil to the fuel to reduce the jumping readings ...it will clean some of the reostat..
