What kind of vacuum line does a Ford 300 have?

When did the Ford 300 6 cylinder engine come out?
Ford 300 Inline 6 Cylinder Engine The Ford 300 inline six-cylinder engine was first introduced for the 1965 model year to be used in the popular F series pickup truck. Ford would keep the 300 in production all the way up until 1996.
Is the Ford 300 inline straight 6 still good?
Today it is not uncommon at all to see a Ford 300 make it to 300,000 miles or more with no major problems at all. Because of its great reputation for reliability and ease of maintenance, the 300 I6 is still sought after among many Ford enthusiasts.
What kind of transmission does a Ford 300 have?
This was enhanced even more by an available transmission setup that offered either a 6.32:1 lower gear in the T-18 manual transmission or a 6.69:1 lower gear in the NP-435 transmission. Today it is not uncommon at all to see a Ford 300 make it to 300,000 miles or more with no major problems at all.

What is the vacuum line configuration on a 302 V8 truck?
On that old Ford the transmission modulator is a critical input. If no vacuum is applied the line pressure would be extremely high and upshifts would be extremely high and harsh. What year truck?
What kind of vacuum cleaner does a Ford F100 have?
Edited by kylehaley84, 29 December 2014 – 05:55 AM. I am the go to guy for vacuum diagrams. or tell me all about your truck. Re-doing a ’79 F100 that doesn’t have any stickers on the valve covers, It is a 302 with egr, pcv, canister and thermal control damper on the air cleaner.
Why did Ford use 2 vacuum lines in the engine?
This is ancient history to me but I believe the reason for 2 vacuum lines was because Ford used a dual-diaphragm modulator valve that was supposed to help shifts and in turn aid emissions. This used both manifold vacuum and ported vacuum from the carburetor body and did not work too well.

Where are the vacuum ports on a Ford 78?
The red capped port will stay capped, and the ports on the passenger side, and the driver side on the front, are what will get used. I drew up a diagram based on everything I had on hand. It uses a blue ported vacuum switch (fully switched at 95°F). It doesn’t have the vacuum circuit for overheating.
What does the vacuum line on a truck mean?
The vacuum lines to the transmission tell the transmission’s vacuum modulator how hard the engine is working. Low vacuum means it’s working hard, because you have the throttle open more, high vacuum indicates the engine is not working hard because the throttle is closed more.
What kind of vacuum switch does a Ford’78 use?
I drew up a diagram based on everything I had on hand. It uses a blue ported vacuum switch (fully switched at 95°F). It doesn’t have the vacuum circuit for overheating. I learned that requires a red ported vacuum switch (open at 235°F) with three ports to switch between ported vacuum and manifold vacuum. My engine doesn’t have one.
How many ports does a Ford 351M vacuum need?
I found something that says EGR Port vaccum from the carb needs to be run to a ported vacuum switch. When cold, it runs vacuum to the advance. Once it warms up enough, it switches over to the EGR. But, I went and double checked… This system sounds like it needs a three-port VPS, and both on my 351M are two-port.

When was the Ford 400 vacuum connection made?
I did manage to find a vacuum diagram for the 400 dated for June 78, which was about a month before my car was built (as well as a couple 351M diagrams dated well after my car was built). But it includes a three-port PVS along with a pair of two-port switches. So, I’m not really sure it applies to its cousin.
