i have a 93 del sol si d16z6. I am installing nitrous and i need to know, whereabouts are the two unused vacuum lines. the zex site said one should be comming off of the intake plenum and another off the fuel pressure regulator. if you all could maybe give me some pictures and circle it that would be great. anything will help let me know thanks.

 

Sorry I lost my drawing "paint studio" thing. from the glove-box view, the left vac line is going to the Intake manifold, smaller vac line directly across from the "P" in A-SPEC.
The inner line in the top pic is going to the FPR at the front end of the fuel rail. hope that helps.

 

circles please anybody!!!!

 

i dont know if you should be attepting this if u dont know what the fuel preesure reglator is. but any who there's a short vacume line that goes from the intake to the fuel pressure regulator it's appoxmently 6 inches long. take that off and put somewhere for later use if u take the zex kit off. use a new piece of vacume line and go from the manifole to the zex box then another peice from the zex box back to fuel pressure reg. it's wierd small circluare piece on the end of the fuel rail on the divers end.

 

 

alright i know what the regulator is i never said i didnt i just didnt know what they meant by unused vacuum lines. and now i do so thanks for the info i appreciate it
