Dude. You won't get very far on a cruise with a tiny fuel cell. Its about the best weight saving you can make, but it comes at a very hefty price: cells generally contain enough fuel to go the duration of the race and don't hold enough to go all that far.
Why are you thinking about a fuel cell setup to cruise around anyway? Sounds to me like a huge waste of money especially seeing as how the Earl's and Speedflow fittings don't come cheap at all(bomb-proofing my fuel system cost almost AU$600 by way of OS lines, braided lines and fittings, and this is with retaining the standard tank! I'd need a trailer to go to the track if I went with a fuel cell because of the tiny capacity)
All in all, its a great modification for a track or drag car but it's about the worst modification you can make to your road car. And its an even bigger pain to get an engineer's certificate for(see reinforced skin) Are you trying to go for the "race look?"
