Hotrod, I agree that fuel should never be put in the intake and I don't care for starting fluid. However, If a system is completely dry, I don't know how you get the air out of the injector lines other than cracking the lines at the injector. In the mean time, I will continue to crack the injector lines to bleed the air on my engines with Roosa Master systems when my guys run them out of fuel. It has been working for me for 45 years. I figure it will continue working for me.
