Picky, picky, picky. That's the trouble, once you get educated you all become critics !
Naturally it is best to go factory original on the fuel pump, the fuel lines, wiring clamps etc. etc.
You can say this Carter installation was for "demonstration purposes only" or for the "photo shoot" or for the emergency "roadside installation". Once the mounting, wiring and plumbing were worked out and finalized, the correct hoses were installed, a rubber boot was used to cover the wire terminals and the metal fuel pump cover was installed.
Yes Walter, only correct rubber fuel lines should be used for fuel. In this case they need to be rated for gasoline at 60 PSI or more on the pressure side. The feed side to the pump can be the standard 30 PSI fuel line since it is under no pressure. Never use a hose rated for coolant for fuel, it will start swelling and degrading almost immediately.
I have seen new old stock factory fuel lines fail before their time as new fuel formulations quickly degrade some old rubber fuel lines. Use newer inventories on fuel lines.
