Step 3

Cross tails, take up slack & ensure wire is not too close to tube end prior to twisting.  A needle nose pliers works well here.  Twist wire about 1/4" Do not be too concerned if a small gap under twist is present as the second wrap provides tension.

Step 4

A slight dent in the tubing is all that required for positive retention.  Too much and you can cut through the tubing.  Trim wire end and fold down.  A peice of shrink tubing can even be used to cover sharp wire ends. Do not use shrink wrap inside fuel tanks.
