Vacum hoses loose, where do they go? 1990 ford f150 4.9

Brother took engine apart to replace fuel injectors, left the truck for me to fix. He didn't label the vacuum lines. The diagram is under the hood, but not complete enough. Can't figure out whee the lines go. Example, throttle fuel pressure sensor has one hose connection that goes to the intake manifold, On the other end it has two hoses coming out the other end...where do they go. I need a good diagram.

    ok so any guesses on where the two hoses would go?Being they are from the throttle sensor valve? Or where I can go to get a better diagram? Chilton has the same diagram that is under the hood it is not complete

There was a diagram under the hood from the factory of the hoses. We do not have the diagrams.

SOURCE: Vacuum hose missing

Your PCV valve has two port's, it also should have came with a plug ( Plastic ) That you break off of the PCV and plug the small one.Canada Emissions is the only one that uses both port's.

SOURCE: Ihave a 2001 Ford Escape.

Check to see if the catalytic converter is plugged. An easy way to do it is to remove the oxygen sensor from the manifold or exhaust pipe (if it is located infront of the cat). This will open a small hole for the exhaust to escape from. If the cat is plugged, you'll see a noticable difference in power.
If you've had bad sensors, there is a chance it's plugged. You could remove it and try to blow the clog out with compressed air. If that doesnt work you'll need to replace it.
for a temorary fix, break the ceramic out of the inside of the cat with a bar or pipe. This may be illeagal and will throw engine codes if you have a O2 sensor after the cat.

I have vacum leak on top left side of my engine as if u were standing on the passengers side of the car its a hose that goes in between the 4th and 6th fuel injector, right underneath were the fuel lines...

If the hose itself is leaking replace the hose. If its the plastic fitting, remove the hose, remove the plastic fitting from the intake (should clip in), replace the o-ring on the fitting, reinstall the fitting into the intake, and install the hose onto the fitting.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa
