Has anybody replaced all those plastic vacuum lines with rubber hose? My brother's truck (92 F150, 5.0L, MT) has thrown a lot of codes all at once for pretty much all the vacuum related sensors. We just swapped the engine and the wiring/vacuum harness did get beat up a bit, but I went over the whole thing inch by inch and I am still not 100% confident that it is leak free. Thanks.

 

one more thing - I wanted to make sure all the vacuum stuff is solid before I start looking at replacing expensive sensors. I was thinking I could make a repalcement rubber vacuum setup for a lot less than sensors that may not work without vacuum.

 

I replaced all mine with rubber vaccum hoses i got about 30 ft of hose just for some extra, and a variety pack of those plastic t's and what not. Mostly used the forks and the t's. Just read the vacuum diagram and follow the directions use your old plastics for reference. Afteri got it all hooked up correctly the engine purredlike a kitten.
