im sorry if my information is hard to understand.(it would really help if someone could show me a diagram***my car is 89 GTU nonturbo)

 

All the info you need is in the Factory Servce Manaual. If you don't have the FSM, click here and download it in PDF format for free. Look in the Fuel & Emmission Control Systems (Non-Turbo) chapter.

 

thank you for the FSM!
