One line made it 400 miles before breaking at the fitting. One week later another line has a pinhole in it. I’ll be replacing all with the old lines I removed tonight and ordering new lines from CAT tomorrow. I do not recommend these injection lines!

The metal they are made of is softer than what you will get from cat . I bought this set to keep under the bunk. When I broke a fuel line I replaced it installed all the clips put it back just like it should be. About 3,000 miles later the new line broke, at least I was close enough to home to limp in. I will buy another set but only as spare parts to get home on it’s a fair price compared to loss of revenue and shop time or a road call. Also I haven’t broke the one I got from cat make sure you have clips on them because they will not last at all
