In my lovelife corolla, I used the 60L cylinder type tank. My spare still stays in my spare tire well. Trunk space has been reduced by over half though. But still enough space for a week or two of grocery shopping.
From what I have gathered, it depends on the vaporizer & frequency of use. Mine has never been overhauled since it was installed. I just have it drained of water once a year.Does the vaporizer need to be overhauled regularly (like yearly or so)? According to the technician at Clean Fuel where I fill up, this should be done annually. He advised me this when he noticed during tune up that the rpm adjustment no longer affects the way my engine runs during idling and suggested an overhaul.
