Just sold these. I knew they would not last long. To get these on, you tape up the fuel line and edges of the cover and very carefully slip them on then remove tape. They say it helps to heat them a bit in the sun to promote flexibility to get around the fuel line. I never installed these because I knew I could not stop once the engine mods started and I have been there before.I did help a friend put his on though and they went on fine with no scratches, but you don't want to do this job in a hurry
