I try to fill up at the light. When the low fuel light comes on I have reliably had 5-6 gallons left in the tank. Light came on at 503 miles, but I typically get 450 miles to the light. I filled up at 519 miles and put in 34.8 gallons. Cruiser gets much better economy at 60-65mph than it does at 75-80mphWith your LRA tank - you must be getting 500+ miles between the fill ups!
