It's time that I must pull the tanks, so I am going to install the hard lines off the tank, move the feeder line outside the frame, and all that stuff at the same time. A friend has suggested using nylon(?) lines instead of steel lines, as all new cars use.

His reasoning is that: a) all the newer cars use nylon lines, and they are impervious to all the brews and concoctions that the mfgrs of fuels might come up with. b) They do not absorb heat as rapidly as does steel, so are less likely to contribute to vapor lock. c) They are somewhat flexible, making it easier to route them. d) They are fairly cheap, e) even the fittings are pretty cheap as it turns out. f) Since the new car manufacturers use them in todays hot engine compartments, with proper anchoring, they should be safe. g) No rubber lines are needed to absorb engine vibrations and flex. h) They can handle EFI fuel pressures, whereas some rubber lines cannot. j) Quick disconnect fittings are readily available for nylon lines. k) With nylon lines, fuel has less restrictions to flow, since they are an end to end solution, with no restrictive or turbulence causing fittings along the way.

These types of lines have been very difficult for the average guy to work with in the past, and the tool to install the fittings is expensive (~$100). Here is an alternative to that tool, and more information about them.

I have not yet made a decision on whether I'll use steel lines or these nylon lines, and I'm leaning toward sticking to the steel lines. I'm just starting my research. However, it's something to think about, as some of the arguments for them are quite compelling.

I wanted to ask Emory's opinion since he has done the hard line change, but he does not accept PMs. Hopefully he will see this and respond with his thoughts.
