The stock pick-up and baffle does NOT ride on the surface of the fuel if it is installed properly. In fact, next to using deteriorated or dirty parts, improper installation is probably the the second biggest cause of problems in the fuel tank. I will agree it can be difficult to properly assemble the stock parts inside the tank and get everything positioned just right. Once done though, it is a pretty reliable system. Having aluminum parts in the bottom of the tank is not the best idea. Water also gets to the bottom and will corrode the aluminum. The plastic/nylon parts are not affected by water or fuel. Dirt is the biggest problem followed by old, stale fuel. Just because the stock parts don't last forever is not a good enough reason to reengineer the fuel tank assembly. If, after 25 years, some parts are worn out, IMHO just replace them as long as correct replacements are still available. The baffle is also like a small container where the returned, excess fuel is dumped into the tank. That way, when the tank is very low the pump can still get enough fuel so it doesn't suck air.
