Re: PVC Tank How To
You can cut washers out of plastic from soda bottles, gatorade bottles, and the caps to those. They will hold up to fuel for a long time. I have used gatorade jugs for replacement fuel tanks on resurrected lawnmower engines. Look for baby formula bottles (1Qt size from Similac etc. They have large, soft, flat sides that you can cut with scissors easily. Coffee can lids might be a similar type of plastic. Do not use the green mtn dew bottles for anything with fuel! IT MELTS. I used to carry spare soda bottles full of weeder gas for weed-eating at the cemetary (all day job). The clear ones work ok if they have a pinhole vent. The green ones melt!
