Coils for these cars are pretty cheap too, and readily available.
As far as the rubber fuel line goes; Ideally, you would like to have metal, but in reality, if you use the proper rubber fuel line you are pretty safe.
The fuel line from the tanks to the two small block GM (Mercruiser) motors in my boat are rubber all the way from the tanks themselves to the fuel pumps. That's the way most boats are. I've never had a problem with them, and can't think of anyone I know ever having a problem either.
But, and this is a big but, they are the proper rubber lines made for use as fuel line, are carefully routed throughout the bilge, secured in place, and properly clamped.
