OK... time to educate the old man...  I have a need to replace a section of 
flexible air tubing on a
air bag jack.  I fabricated a new handle to give the jack more reach and the 
original tubing is too short
 
I tried replacing original with H.D. stuff but it was too stiff to  slip over 
the fitting... The original tubing
is amber colored and very pliable...squeezes easily between your fingers.. the 
H.D. stuff was stiff
 
It press fits over a fitting with a holding nut keeping it in place.  I would 
imagine the working pressure
would be around 100#s since most compressors put out that much   
It's i.d. is 3/26 and o.d. is 5/16 or
its metric equivalent.  Only markings on the orig is "013M" but I don't 
think that means `13mm'
 
so first question  … what type tubing do I need  vinyl ??? PVC ??? Polyethylene ???? 
second question  … where to find it   """  pics attached
 
thanks
john
