as my former working experience at RIIFO, I know that RIIFO has a set that are especially for transfering gas-PAP and PEX tubing with F5 fittings. As I learned that gasoline transportation can be done with PAP or PEX pipes, and it’s OK to connect F5 fittings. But gasoline corrosion resistance of PEX is grade C, which implies that at 80℃, the maximum operating pressure does not exceed 60% of the working pressure, that is, the design working pressure is 6bar, and the maximum gasoline transmission pressure is 3.6 bar.
Both PE/AL/PE or PEX/AL/PEX pipes can be in contact with LPG for a long time. The melting point of PE is 125℃, and PEX does not melt.
So I think the answer is YES!
