This very important! Never use camping fuel it contains alot of additives. Also PVC is a bad idea use a stainless steel turkey baster (pick them up at upper end bakeware stores) PVC will release nasty chemicals when doing butane extractions.
Ther is a brand of Butane that is filtered five times that is sold at cigar shops but the name escapes me at this time.
