I've read the life of fuel line's is 8 year's, so just replace all at the same time.

Eight years eh? OY! I'm heading up to the dealer tomorrow, I'll look at those lines, eight years on mine... May as well have them replaced as the truck is already in pieces and in the air! I don't know why I didn't even think of those. I am having some other lines replaced for the transmission...
