				Hi group.
     I am changing my clear plastic gas lines on my  Kolb  firestar , with a 503 rotax , I use a pulse pump, elec . fuel  pump, gascalotor,  and a fuel filter...the gas line I use is the heavy  clear plastic line that I get from Lockwood avaition...it is also used for pulse  lines....the old line is discolored and been on about 4 years now...here is my  concern....when cutting the old line I noticed that the inside of the line was  coated with a very smooth white substance....I took a knife and scraped some off  and it scraped off like very fine dust....the line had been with out gas in it  and was dry...the engine has run perfect with no trouble....I still have to  finish replacing the new lines and then will start the engine for the lst time  this year....your thoughts as to cause of the white build up inside of old line  and cause is needed......I am using 87 octane car gas and pre mixing phillips  air cooled 2 cycl oil  50 to 1.....and have for many  hours....thanks    Jim Swan
