I used tube tech for my 69. It is all stainless & comes with everything. Was simple to install.

I am doing a 68 firebird now. Its more of a budget build. I decided to try to modify the stock hard line. I bought a new stock line & C5 vette filter. Bought the fittings for the quick connectors from summit & had a local shop make me some steel briaded lines to go from the engine to hardline & from filter to tank. I have about half the money in this than the tubetech setup. It took 3 times as long & a lot of measuring & running around. I think if I did it all again I'd just buy the tubetech setup.
