I’m going to keep this simple.

some vacuum hoses are broke and I’m getting 11 mpg.

how do I fix them. Thanks!

Find replacement hoses in local parts store and replace all hoses, IMO.

I'm having similar issues with my '88; most hoses are having split ends and need to be replaced.

I will keep my answer simple. If hose is damaged replace it, move on to next hose, if damaged replace, move on to next and so on and so on .................

5/32 rubber vac hose will splice over the hard line and join them together.
