Thanks for all the help and such guys, sorry bout the long reply, I got a bunch of help here this morning and pulled my motor, got it on the stand and got carried away with installing my Driftmotion stuff. (They really are great to deal with BTW! And my order was BIG, complicated and HEAVY).
I would have thought the softlines inplace of hardlines is simply a bad idea from a more easy to rupture angle of concern. My car doesn't ever see anykind of weather other than nice though so I doubt the danger would be much higher. I also worry about the track saftey guy turning down my car during saftey inspection perhaps.
I am running all steel braided lines under the hood, to and from all the various bits and such and ya it looks great. But where they tuck down under the transmission tunnel and head back from there all lines get attached to what I assume is aluminium tubing with threaded connectors. Whatever the stock sizes may be.
Dropped my fueltank yesterday and it looked fairly clean inside after 20+ some years, no nasty sand filled nightmare like someone was so unlucky to get here recently. Anyone here running a fuelcell at all? I never run with a spare tire in my car and the fuel tank seems to be really convoluted outa shape to form itself to the bump for the tire. I believe they are lighter, although granted it is backend weight. Seems to me you could likely put a tank right in that spare tire well easily, a good sized on too. Not sure what this would do to the airflow dynamic under the car though, if there are really any to speak of to attempt to preserve.
