Okay, having a bit of a lapse here, does anyone know whether the fittings on the braided steel fuel lines off the back of the TBI are flange style fittings or O-ring style? I am talking about the end away from the motor. Also, the air cleaner stud was missing when I got the engine and I found it today laying on the intake under the cruise control module. It has been broken off. It's been awhile since I have messed with a TBI, so where does this thread into the TBI, is it right in front of and between the injectors? Thanks for all your help with my stupid questions.
