I am new to posting on this forum and very new to working on cars so forgive me if I am asking something stupid or repetative.
I noticed in part 4 of your sentra 1.8T project car (
http://www.nissanperformancemag.com/january05/qg/) third paragraph it is written that the 1.8s has a "return fuel system." I googled this, looked through the forums for a while, and could not find anything about this. Is the unused fuel filtered at the cat and routed back to the engine? or is it just a term for something every-day i have never heard of yet?
