with regard to any work on the typical fuel distribution system. has anyone ever used gaseous nitrogen to purge gasoline vapors from the entire system prior to opening for tank repairs, hose replacement,etc? seems as though this would remove most of the fears in working on the aforementioned items without the concern of lighting up one's self. what does s.f. have to say along these lines?
While it's obvious that gasoline is a fire hazard, unless you are smoking, grinding or welding in the immediate vicinity (not recommended) a little common sense should suffice. Keep an extinguisher handy and work in a well ventilated area (outside is recommended). Keep in mind that gasoline vapors are heavier than air and will collect in low places. Purging tanks and lines with inert gas can't hurt but unless you keep the gas flowing continuously it's difficult to assess whether you have saturation or not.
