The engine compartment is very hot, and hoses are vulnerable to heat. But
the main problem is that if it does leak (and all rubber hoses leak
eventually unless they are replaced frequently), it spreads fuel over very
hot surfaces with a high probability of ignition.

I confess that I use a hose from my solid line down at the frame
crossmember to the carb inlet, but it is high-temp aircraft-grade hose with
AN-6 fittings. I would never use a plain rubber fuel hose over the top of
the engine.

As to the plastic fuel filters, even moreso. Just below the pump is quite
close to the exhaust manifold, and you do not want to spray fuel onto that.
The FRAM G-15 filters are in steel cans and they are easy to get and easy
to install.
