There is fittings available for what you need. When you cut the line for proper length you need to wrap the line with tape such as 1 inch wide masking tape and then put it in a vise to hold it, but do not sqeeze it and collapse it. Just tight enough to hold hose. Then cut it through the tape where you have marked the length needed using a good cutoff wheel on a air tool. It is easy to do with an air tool however you can do it with a hack saw if you do not have air tools. The fittings on the hose comes with a sleeve that screws on to the hose. You have watch to make sure that you do not bottom out the hose in the fitting but it will be close. Then screw in the inner part turning the opposite direction. Blow out the hose with air before installing. Then admire your work before installing. It is not hard, just time to learn a new skill.
