To connect rubber hose (SAE 30R7, 30R9) to 3/8" AL tubing you need to 'bead' AL tubing. This is a must since there is nothing to keep rubber hose from sliding of the end of the AL tubing, but a bead will keep it in place. Forming a bead is easy with a right tool. If you are planning to work only with 3/8" tubing than Earl's EZ-BEADER will produces a correct bead per SAE requirements. Look for Earl's part number 008ERL which is designed to bead 3/8" tubing.

If you are planning to do other tube diameters you can purchase additional EZ-EADERs from Earl or go with professional (pricey, but very nice) ATS Tube Beading Kit. I hate to admit, but I am a tool freak. Sorry, it is a weakness

As far as safety is concerned. Fuel supply line must be built to withstand up to 50 PSI. The reason for this is that most TBI service rated pumps are capable of 20 to 40 PSI deadhead. Fuel supply must be either AL tuning (0.035 is good) or -6 size braided fuel line. I used both in my conversion since I had -6 line on hand and later I picked up the spool of 3/8" AL tubing.

Beading tool is a must if you plan to attach 3/8" rubber hose to a fuel line. Otherwise plan to spend on -6AN adapters and hose ends.
