What pressure? When the SP500 had the stronger alloy tanks up until 2003 there never was a problem, its the weaker plastic oil tanks that are giving out. There older pre 03 SP500s with 10,000 miles still running around with there original oil tank and motor.

 

yeah, 10/4 TLc, the ones i remembered were in the winter within a month from each other. cold probably made the thin plastic brittle.for the only 20 dollars or so i'd be changinging the plastic one yesterday,,,,,,,,,
