How to reconnect vacuum line behind intake manifold?
To reconnect the hose, you will either have to remove the intake or get the truck in the air on a vehicle lift and reach up on the drivers side of the transmission to reconnect it. Also, can you give me the VIN#. Ford did have a recall on this vacuum hose for this very problem.
Is the base of a vacuum tube replaceable?
Most vacuum tubes have a limited lifetime, due to the filament or heater burning out or other failure modes, so they are made as replaceable units; the electrode leads connect to pins on the tube’s base which plug into a tube socket.
What does it mean when a vacuum tube is overloaded?
When a vacuum tube is overloaded or operated past its design dissipation, its anode (plate) may glow red. In consumer equipment, a glowing plate is universally a sign of an overloaded tube. However, some large transmitting tubes are designed to operate with their anodes at red, orange, or in rare cases, white heat.
Where did the idea of a vacuum tube come from?
The earliest vacuum tubes evolved from incandescent light bulbs, containing a filament sealed in an evacuated glass envelope. When hot, the filament releases electrons into the vacuum, a process called thermionic emission, originally known as the Edison effect.
Where do you find the code on a vacuum tube?
Look at the print on the vacuum tube to identify it. A series of numbers and letters is printed on the side of every tube. This code is what you use to figure out where to place the tube in the tester. For example, the lettering on the tube reads something like “12AX7.”
Where do you put a vacuum tube in a tester?
Look at the print on the vacuum tube to identify it. A series of numbers and letters is printed on the side of every tube. This code is what you use to figure out where to place the tube in the tester. For example, the lettering on the tube reads something like “12AX7.” Insert the tube into the tester’s socket.
Are there any vacuum tubes that are still made?
Some brands still produce vacuum tubes, but its often possible to find new or used tube models made by brands that discontinued production years ago. Some examples of the brands that make these electronic components include Amperex, GE, Mullard, RCA, and Sylvania.
How can you tell if a vacuum tube needs to be replaced?
Before turning on the electricity, give the vacuum tube a quick inspection. Notice any evidence of broken glass or bent pins inside the tube. Loose parts or discolorations are signs that the tube needs to be replaced. If you see that the tube is broken, don’t test it.
Where are the outlet ports on the intake manifold?
Because of this, the intake manifold will often have many vacuum outlet ports found on it. Vacuum Accumulator / Vacuum Box Some custom application intake manifoldsor those manifolds equipped with individual throttle bodies, do not have enough room to accumulate sufficient engine vacuum.
Why does my engine not have enough vacuum?
Because of this, the intake manifold will often have many vacuum outlet ports found on it. Some custom application intake manifolds or those manifolds equipped with individual throttle bodies, do not have enough room to accumulate sufficient engine vacuum.
What causes a vacuum line to leak at idle?
Having a good seal from the piston rings most people understand, but when running a very large and aggressive cam, often there will be more overlap in the duration between intake and exhaust valves that will cause a loss of vacuum at idle. This loss of vacuum causes the motor to struggle when idling at low RPM’s.

How do you remove plastic connector from intake manifold?
To disconnect the plastic connector, you need to press in the grey ring and then pull the whole connection off the brass fitting on the intake manifold. Unbolt all 10 8mm bolts that hold down the intake manifold to the engine. These are the 10 bolts that DON’T have threads on both ends.
Because of this, the intake manifold will often have many vacuum outlet ports found on it. Some custom application intake manifolds or those manifolds equipped with individual throttle bodies, do not have enough room to accumulate sufficient engine vacuum.
