First of all the person that installed the hose may have
screwed up or pinched it while installing the hose.
Second make sure that you get a locate a business that
specializes in building hydraulic hoses, don't mess around.
Third, I have seen far more problems than a bad hose
problem here, this seems to me be a minor problem.
The other problem I see here is that if you are so worried
about this hose ask a local parts store or NAPA where
you can find a local business that specializes in building
hydraulic hoses and have it fixed there. I hate to be so
harsh but I can see if the hose breaks the you will have
hyd fluid all over the bottom, then complain about that,
so get it fixed thus you can sleep and not worry.
