Going to jump around here some. ALL combustible fumes are poisonous but alcohol fumes not only stink but also make your eyes water, bad. Watery eyes and cutting a good light don't mix well. Plastic 8 gallon fuel cell which I removed the foam. Barry Grant 400 fuel pump set at 5.5-6 pounds pressure. Number 10 black fiber line ran to front, number 8 to front and back of carb out or regulator. I do not use a block heater as the system I posted above works for me. My son has a water heater in his block that goes into a soft plug and are sold by jegs. If I prime my carb, give it 3 pumps to the floor mine starts well for me so I use this technique for my first start up of the day. If it's 20-30 degrees out I use the above technique plus I may dump a small amount of gas into the carb. Nothing special between races or at the end of season. Float are Polyurethane and listed for alcohol use at Summit. Stainless steel or titanium needle and seat. If I had a toilet set-up I WOULD have a primer plus system to aid heating and to save fuel but I don't.
