I run alky injection and have a primer on mine that I use to build heat and start the car with regular pump gas. I put alky in mine back in April and haven't touched it since. I run a vacuum pump so my oil stays as clean as if it were on gas. Can run it a whole season on one oil change. At the end of the year I drain the tank, blow the lines out, spray the barrel valve and pump down with WD40 and let it set till next spring.
