rubber fuel line

I've never heard that but then practically all cars use steel fuel line. Vapor lock is caused by the fuel line being too close to hot engine components and the gas vaporizes forming a bubble that prevents the flow of fuel. Years ago we would wrap tin foil around the fuel line as a heat shield,and it worked OK. Regardless, rubber fuel line has no place on a motor, as the risk of fire is severe. It is used in short sections to make the jump from the car frame to the motor, but it is far away from ignition sources.
I would say that it really depends mostly on where the line is in relation to a heat source. Most fuel lines are metal for more than one reason. Reliability, durability, and safety. Rubber lines are necessary to allow for movement or ease of replacement, such as near a filter. Metal is almost always the better choice in most areas and applications, but can be more difficult to fabricate. Metal has a longer life span and doesnt swell or collapse the same way rubber lines do. Get the best rubber lines you can find, such as for fuel injection systems, which are 3 times the cost, but are 3 times better...JMOmobileaudio25 said:
I would recommend braided lines. There more expensive but more durable compared to rubber and more flexible compared to steel. Best of both worlds IMO. I was always replacing my rubber lines like every 6 months due to dry rot and I made the changed to braided last weekend. Oh and I forgot, they look a helluva lot better than steel or rubber 8)
Also remember that old rubber line doesn't meet the new requirements for alcohol resistance. I forget what year but the US Coast Guard mandated a new specification for alcohol resistant fuel line to prevent boat fires when alcohol became common in gasoline. The automotive industry later followed their lead. Old stuff found in your garage or basement may not be resistant. Rubbing the line with a rag soaked in gas will test it. If you get black moosh rubbing off, don't use that for fuel line.
I'm upgrading my fuel pump and adding an inline fuel filter, this is why I am asking...
I'm running a steel line from my pump to the carb with only about 3 inches of rubber hose for the filter....
My local napa carries a high pressure fuel line that I was looking to use from the tanks metal line to the new fuel pump. I was planning on running the rubber through the frame or up the inner fender furthest away from the headers as possible

Using high pressure fuel injection hose has no advantage (unless of course you're running close to 50psi or more) If you are running steel fuel line 95% of the way, why wouldn't you just get an inline fuel filter with inverted flare inlet/outlet and run the steel line the whole way :?: A 3481 NAPA GOLD fuel filter would be perfect for you 
The quality and alcohol resistance of HP rubber fuel line is vastly superior to general purpose hose....so there are some advantages in my opinion.
