Hi All,

I was looking at my engine bay today and saw some lines that seems to be vacuum one that are not connected... I am attaching pictures so you can tell me what I shall do please.

The car is a 951 from 1986.


Thank you

At first i saw only 2 and 3 and thought they were to be connected but then looking in i saw 1 and i got lost…

Can someone help me?

There are some very good vacuum line diagrams online. Let me try and find one for you!

Check this out and let me know if it helps. I haven't had a stock car in so long I don't remember what goes where.

Thanks Darwin, but not being a mechanic, it is a little hard for me to understand.

So, what would help is that someone that could tell me if I shall plug 2 into 3 for example or if they shall be this way.

Thank you please let me know

Here are some easier to read diagrams -

Probably a good idea to get the Lindsey vacuum line kit and replace all of those.

2 probably goes in to 3, but verify that 2 goes to the fuel pressure regulator per the top diagram on the lindsey site. Not sure what 1 is... so you'll have to trace it... I see you have and adjustable fuel pressure regulator per picture 1.

Hi Brantley,

Thank you for your feedback, i will then connect those two together as yes 2 come from the fuel pressure regulator.

As per your question i think the answer is yes i do have adjustable fuel pressure regulator, I am not really sure why as i just got the car, which is a little special as it is a 2.8 andial stroker.

This might help. Had to take care of a few lines not last week.

It's hard to say with certainty because picture don't allow you to see where the other ends go (and so many vacuum lines all look alike at one end). That said, in the fist picture below, is there a black rubber hose connected to that banjo bolt where the yellow arrow points? There should be, and it should go to a three way tee (probably one of the other ports on the #2 tee you point to. That tee has one hose going to the FPR and another hose going to the another tee near the front of the fuel rail. The second tee then has one hose going to the fuel damper at the front of the rail, and one hose going the bypass (blow-off) valve on the right side of the motor. I tried to draw it below.

Where does the other end of #1 go? And is #3 disconnected on both ends or is the end with the rubber piece on it a tee and/or connected to something? There is a hose on your FPR. Where does that go?

Hi Tom,

Thanks a lot for your feedback, to answer your question to the best of my ability.

#1 come from the upper side/top border of the engine where a lot of cable are (would be on the left on the above picture where i point my finger parallel to the windshield), and #3 come from a tee that connect to the AFR

Hope this helps
