How to deal with paranoia about fuel leaks

Yeah, the SAE J30 R9 spec "low emissivity" hose is more expensive on a $/foot basis, but if you're replacing regular hose every couple of years (or more often) and this stuff lasts for ten years then which is the more expensive hose in the long run? I don't know that this stuff will last that long, but given the OE's warranty situation they need 100k mile fuel hose. The liner in the R9 spec hose looks to be either teflon or polyethylene and either will stand up to this strange stuff sold these days as "gasoline."

For hose clamps the best that I've found thus far is "ABA" brand and the most reliable place that I've found to get them is West Marine. These are the type with no holes in the band for the rubber to extrude through.
