Greg installed a 3/8" steel line down the center of my Spyder. It has a threaded end in the back, I installed a threaded brass T, and ran hard lines up each side, screw-in metal filter on each end. Just a short length of new German braided hose to each carb, secured with spring hose clamps.
Up front, I used a compression fitting on the hard line to a hose bib. I guess I could have just flared it a little. Short piece of hose to the pump, even shorter to the metal can filter, and then one more piece of hose to the tank. All secured with those spring hose clamps(NAPA) I mentioned.
Minimal rubber hose, maximum metal line, no plastic, no glass, and good clamps that do not damage the hose. Change the hose every 5 or 10 years and you're good.
Even with all that, the fire system is the way to go. Snuff it out before you even get out of the driver's seat. Seconds matter.......
