gas tank sending unit

In a recent post here I pointed out that the sender had been improved in the physical or mechanic aspect. The original, long, one bend, sender had its faults. At approx' 1/8th of tank, that sender float would bounce against the bottom of the tank. Steel ( the harder metal ) wears brass. Float gets a hole and sinks.
Backing over objects like tricycles is one of many ways to distort the tank. The one bend tube is quicker to move the flange, break the seal, open the bottle. The multi bend tube not only is more apt to distort at more than one bend thus protecting the seal but seems to improve siphon and resist the soda straw like backflow too.
Every time I read a post where owner stated he bent the float arm attempting to improve aftermarket sender signal, I want to reply, "Keep a 1/4 tank minimum fill or go ahead and buy another float".
