Fuel Line Plumbing?

By the time you buy the GOOD aluminum tubing, not the stuff that Summit sells, the industrial aeroquip teflon isn't that much more and you will have fewer opportunities for leaks because the good aluminum is usually restricted to 6 foot lengths unless you get coils and have to deal with wavy looking lines.



Here is a good tutorial:

Here is my 2 cents on working with the teflon. Take 3/4" painters tape and wrap the teflon braid 2 or three times adjacent to the mark on the hose. This will ensure that you will get a nice square end when you cut the outer braid and the inner teflon core. Take a dremel tool (not a die grinder) with a thin cut off wheel and follow the edge of the tape around, cutting only the braided portion of the hose. Don't cut the teflon liner at this time. Follow up by cutting the teflon with a sharp razor blade, slicing through the teflon coreas straight as possible. I sometimes use a bench grinder to dress up any imperfections in the brading or the core or to square the end. You could use a file too. Wash the hose out with brake cleaner and blow out the junk that might have gotten into the hose. Clean any burrs off with a small exacto knife. Slide the nut on the hose before putting the ferrule on. Remove the tape and insert the ferrule on the core making sure that no braids are under the ferrule. Use the flat side of a work bench to help with pushing the hose on the ferrule, making sure the hose bottoms out in the ferrule. Take your fitting and chuck it in a vise. Lubricate the threads of the fitting and the inside diameter of the hose with a grease or light oil. I use Aeropuip hose lubricant or you can use a lubriplate or equivalent. Slide the hose over the fitting nipple until the ferrule bottoms out and screw the nut on the hose fitting. I screw the end on until there is about 0.035" clearance between the nut and the fittings hex shoulder. This will give you some opportunity to clock the fitting once installing it on the car.
