Moeller tank discoloration

Installed on a boat that is rarely used and is kept covered and garaged year-round. Only use non-ethanol fuel. Anyone else experienced this? I've emailed Moeller asking if this is normal but can't believe it is, as it was bright white when new. http://oi66.tinypic.com/2i5lds.jpg2i5lds.jpg http://oi68.tinypic.com/nxqaa8.jpgnxqaa8.jpg

This is not a defect. It is normal due to the color of the fuel. Lesson: enjoy that shiny white tank while you can!

I though I read that these tanks are painted anyway to keep the UV from hurting the plastic. Looks like a good ole Lake Hartwell red mud stain:)

I never thought the white ones looked good in a desert tan boat however. I use the red Tempo and Moellers, and they still look great after 12 years now. Trying to keep them away from extended UV exposure is always a good idea.

They normally handle an impact and will shatter when bleached out. Having a red or other colored plastic on a fuel tank is a good safety feature. For years I ran a kayak shop selling those plastic tub kayaks. It was surprising how many cheap people would bring in sun-bleached hulls with huge cracks and want them repaired. After hearing a ton of horror stories, I would give $75 trade in credit just to get the dangerous boats off the water! TP

This may be an option unless you plan to replace with a red tank. Thought to share... Angel M. 1996 Dauntless 15, Sportsman Pkg. - 2007 Yamaha 90 HP 2-Stroke
