After reading the links I consider myself **** lucky to have accomplished this without removing anything. It took a lot of luck in having a clamp I was able to tighten with one finger. Yes you heard me.thats all there is room for and about 20 minutes to attach 1/2 inch hose with 2 fingers . Doing it according to the link, which I am sure is the correct way to do it looks like a big tough job.these hoses should have been fitted on every Spark before assembly was complete . It would take about $1 in parts and 2 minutes.
