How to deal with paranoia about fuel leaks

ACVW's catch fire because of the type of rubber fuel hoses they used. It didn't age well.

X2 on no drip pan, for the stated reason.

Liquid fuel is pretty hard to light on fire (not impossible, just hard). It's vapors are not. Airflow is key, 'flush' the vapors away.

After nearly losing a whole dyno room to a diesel fuel spill I really, really don't like to use hose clamps and avoid them as much as possible. Don't have to go the full AN route to get away from them, but it is an investment. Have a look at "Push-Lock" or "Barb-Tite" type of hose ends. On my Valiant I'm using these fittings with SAE J30 R9 "barrier hose" as an experiment to see how well that hose works with the fittings. Going on a year with no issues.
