Replaced 308 Fuel Hose
You've seen those FFV's (Flex Fuel Vehicle) on the road, but now your 308 can be an FFV...
As stated in several automotive magazines and TV/radio shows, the currrently used flexfuel causes breakdown in older rubber fuel lines. The old rubber used on original 308s will prematurely desintegrate due to the harsh fuel mixture.
For this reason, I had the original fuel hose replaced with a heavy-wall fuel hose made of composite material which is unaffected by flexfuel (up to 85% ethanol).
Just about every oil company is now using at least 10% of the alcohol-based fuel in their gasoline and it is hard to avoid.
To manually test your 308 fuel line, go behind the left rear wheel area of your car and pinch the fuel line from one end to the other. If you can feel any uneven area in the wall (thin in one area, but thick in another), you may want to consider changing the line.
Also before replacement, I had both fuel tanks drained from the middle connection. This allowed for drainage of sediment which may have collected at the bottom of the tanks throughout the years.
The new fuel is with us, so it is a good idea to consider replacing the hose line with new flexfuel-friendly composite material to prevent possible future gas leakage due to breakdown in the original rubber hose.
