Lil Olds started running rough. Tried everything under the sun to fix it. No dice. Gave it one last look and it turned out to be a slit vacuum line. Now the Olds is purring like a Caddy.
LOL! Actually all it took was a pair of scissors. First to cut the hose to length. Then to use as a id deburring tool because the hose i got was too small for the fitting. So ha and a hi-ya!
