Hi. Can't find the specific diagram for my year. I'm changing the aftermarket fuel regulator back to stock and need to know what the vaccum lines are located. Some of mine are disconnected and or rotted. Thanks

 

Do you not have the emissions sticker still on the radiator cover? It shows all the lines.

 

No. Nothing is there. Specifically I need it because i think there is one missing from the end of the fuel regulator. Maybe it fell down or its in wrong spot. This is a car I just bought so i will remove this aftermarket one and go stock

 

It should definitely be hooked up to a vacuum port. 93s are different and I can't find a picture or diagram of exactly where it goes. Post 93s are like this. Yours may go to a port on the driver's side of the intake.

 

The 93 factory manual shows there are two vacuum fittings on the passenger side of the intake manifold, identical to the 94-97. Given the fact the 93 fuel pressure regulator is on the passenger side rail, above and to the rear of these fittings, I'd bet it connects to the same port as the 94-97's.

 

Ok that helps a lot. Thank you

 

Fred, isn't it that way on Corvette's? I thought the 93 F-body regulator is on the driver's side front.

 

Mine was one the back of passenger side fuel rail. Pain to get off but I did. Aero motive and it is junk

 

Ok, cool. I guess I had a wrong picture in my head.

 

Well unless someone relocated it to the rear. Ha

 

I should have realized this from the fact that the 93 intakes don't have a fuel rail crossover in the front, so the 93 rails have to crossover in the rear. I don't look at many 93s.

Fred's never wrong.

 

Yea. This is my first 4th generation and LT1 are another breed altogether. I'm learning a lot since joining this site.
