How to deal with paranoia about fuel leaks

"I think it amazing that all the high-pressure fuel injected cars (since ~1992) haven't caught fire more often."

One thing to keep in mind is that the hose clamps used for FI cars look similar but are different and provide a more even and much tighter clamping force all around the hose end without the tendency of the standard hose clamps to dig into the rubber. Similarly, the high pressure hose is built differently and is a lot more rugged for the 50-60 psi constant pressure.

So, the OP can ask for fuel injection type hose clamps and use those and things will be more secure. Also, just like heavy electrical parts (starters, alternators), don't go to Autozone or Advance or similar box stores for any sort of hose; their hoses tend to be kinda crappy. Get a name brand like Gates if you can or at least get it from NAPA. It'll will be of a better quality.

Good story on the Dauphine and the gas in the bottle....!
