Hey Guys and gals, I recently took ownership of a 99 Limited. The spec for the truck says if has an 18 gal fuel tank. When I get down to the point that the fuel light comes on and I fill it , I can only get about 13 gallons in it. I thought I read somewhere that there was an issue with inaccurate fuel gauges on the 99 4Runner but when I called Stevenson Toyota (local dealer), they have no record of a TSB. Any help would be appreciated. Thanks in advance.
