Getting warning light "low fuel" nothing showing on fuel gadge when tank is over half fuel. Dealer replaced side tank module due to code P1431. A few weeks same thing again. Anyone else have this problem?:shrug01:
Where do you buy your gas? C-5's are notorious for fuel quantity issues. Something to do with the sulfur content of various fuels. I had this problem whenever I bought gas at Shell. Switched to either Texaco or Chevron with Techron and the problem went away. Might be something to consider.:yesnod:
