The original line clamps were in good shape so we formed them to fit the5/16-inch and 3/8-inch tubing using scrap. We placed the 5/16-inch and3/8-inch tubing in the clamp. Then we used a lineup punch to keep theclamp in alignment while it was formed correctly. Installing thefuel-line clamps can be difficult, as the photo shows. Look closely atthe 1/2-9/16-inch slight offset box-end wrench. It was ground to fit theclamp bolts, allowing removal of any fuel or brake-line clamp bolt onthe frame.
