On a multi-port injection system it's called the "fuel rail"
It a special order retainer kit from your local dealer. Dealer item only. Cost you about 40 bucks
It is inside the upper intake manifold. To get to it you must remove the throttle body, upper intake manifold, and several electrical lines and fuel lines.
Which vacc. line and what size engine? Vacc lines are usually plugged into a connection on the intake manifold.
You must take off the upper intake manifold and it is right there. Depending on the year it is generally quite simple. You have to remove the top plastic vortec cover. Then remove the throttle cables. After that there are some sensor wires and 3 vacume lines. 1 vacume line is under the throttle body and the other 2 are behind the intake manifold. Then remove the coil to the ignition. After that there are 10 bolts to the intake manifold. Once you have the off remove the upper intake manifold gasket and then the fuel distrubutor lifts up and out. No bolts holding it in but the fuel lines can be a pian (at least some of mine were)
The pressure regulator is located under the upper intake manifold. Find your fuel lines entering the manifold (right behind where the air enters the manifold)...the pressure regulator is on the bottom side of that cluster*%$. You will need to remove the upper manifold to reach it and change the regulator.
The vacuum lines on a 2000 Chevy Silverado run between the intake manifold and multiple valves across the top of the engine. The vacuum pressure is generated by the engine's compression.
If your engine is a 4.3L V-6 with CPI (central point injection) it is inside the upper intake manifold. The upper intake manifold is bolted on top of the normal intake manifold. The throttle body is mounted on it and your fuel lines terminate into the center of this.
Contour lines connect points with the same elevation or altitude. These lines are used on maps to help visualize the shape and elevation of the terrain.
draw lines and connect them
If it's in the way, then yes. Don't dis-connect the lines, though. Tie the compressor up out of the way.
You usually need a constant source from the intake manifold to the power brake booster, and a spark-ported source from the carb to the distributor. There could be other emission-related lines as well, depending on the year.
The intake manifold on a 1990 Acura Integra connects to the head of the engine. Loosen all of the nuts from the manifold to the head, disconnect the throttle body, vacuum lines, fuel injectors and coolant lines then pull the manifold from the head.
