Measure the inside diameter of the fuel tank filler neck.
Measure the length (Dimension A) of the fuel tank filler neck using a tape measure inside the neck.
Review the available anti-siphon tubes and their dimension (Dimension B) from the underside of the top lip to the tip of the last barb.
Select an anti-siphon tube with Dimension B greater than Dimension A to insure that when installed the barbs will catch on the bottom of the filler neck and prevent removal of the anti-siphon tube.
Insert properly sized anti-siphon tube into filler neck and press into place. If you pull back on the anti-siphon tube after installed and it can be easily removed, it is not sized properly. It is recommended that you re-check of the above noted dimensions.
