I am putting together a DET in a S14 and kinda ran into a problem with a tube running up from the block. I can't remember where it ran too. I think it went to the AIV but I am not sure. I am not talking about the turbo oil outlet. Its the larger pipe above it. Secondly we also lost the place for the outlet on the Fuel pressure regulator.. Not sure where it goes or if it is just a air line leading out??? any help would be great!
