Not to go against you because you know more than me...but for some reason i can fill up from E and only pump in 13gal MAX...RS come with a smaller tank maybe? Or is this not the tank that should be on there? I'm lost, but i know what he is talking about when he means he pumps in 10 gallons at the light. I get around 300 miles ish on my tank in city, at around 22 or 23 mpg. Around 375 on highway at right about 30 or 31 mpg (calculated the last few tanks for kicks). That means i get about 12 or 13 gallons into a tank. I don't know what's up, but i've NEVER pumped in more than 14 gal...even on E. Maybe my float is outa whack so it senses less fuel. My mom's buick has that problem, and i've noticed my gas gauge never reaches full when the pump kicks off. where can i get a replacement float?

Anyhow, sorry for hijacking the thread. Saw a discussion and decided to jump on the wagon because the new guy and i are having the same problem. Welcome aboard man! Use search often...just a word of caution.
