Rubber fuel line will not pass tech inspection. Just not very safe to run that much rubber line.
This weight savings is minimal, and weight can be saved elsewhere, without a compromise in saftey.
Aluminum is the solution, and it bends easilly. Make sure it is supported well, and will not rub on the chassis or frame. Any chaffing will rub a hole right through it.

so, aluminum fuel line is the lightest? cool, i get light weight with a good amount of saftey.
mwvdub: not sure how much weight i can shave off. im going to put some more time and money in to it, get it in to shape and then see if it sells. if not im taking a hole saw to it. i wanna swiss cheese the doors and dash. i havent done it yet because im not sure anyone but me would want it like that. but if no one buys it, i guess no one wants it.

NHRA rules for street class racing is no more then 12" TOTAL of rubber fuel line (braided and pushlok line is ok)
This also applies to auto trans cooler lines, not sure about PS lines.
I ran braided on the ranger and on the galaxie went to alum line and like it, even all the way from the trunk to the fenderwell and I only used half of a $30 roll of it (25ft roll)
one other thought since your doing the fuel system, I don't know what your doing with the truck but NHRA rules say that no part of the fuel system can be attached to the firewall (or even to any body part that directly enters the passenger compartment so don't secure it to the floor pans themselves either) a lot of off road places don't get that picky but you might run into a place that goes by NHRA or SFI rules so keep that in mind when you do it so you don't have to spend more time and money fixing it.

Caution notice
If you're going to use aluminum, isolate it well from any steel in the area. DO NOT let it come in direct contact with any other metal. If you don't, it will create a galvanic corrosion condition in the presense of any moisture and it won't take long to put a hole in your fuel line.
You can imagine the consequences of that scenario, from merely an annoying and smelly cutout of your engine, to a catastrophic and deadly fire.
