I'm having some major confusion hooking up my vacuum lines. Specifically on the Red cable (known as TAB). My diagram shows that it's supposed to split off and connect to the MAP sensor, and also connect to the intake manifold. Vacuum Diagram
I believe I accidentally broke the joint that goes to the map sensor. This is what that joint looks like now.
This is how I plan to hook it up.
My questions:
1) What do I need to buy to replace that broken joint?
2) Where is the MAP sensor in my vehicle?
3) Is the hookups I outlined in that picture correct?
I was looking at pictures of new MAP sensors online, and it occurred to me that there's something square and black mounted near the battery (by the voltage regulator) on the passenger side... I'll go out and look again, I can't remember if it had a vacuum port on it or not.
If that vacuum line is a simple 3-way split, then I should be able to buy something like this. Does anyone know what size tube that vacuum line is?
Also, really glad I realized this wasn't connected.... I assume the MAP sensor is one of the most important vacuum lines to have connected
Yes, that is a simple tee fitting hooking the MAP sensor up. They usually have a rack in the store that has things like that. If that truck was fuel injected, I bet it would not run at all with the MAP disconnected.
