I have the vacuum diagram but does anyone know the sizes for all the rubber lines for the 4.2? Mine have never been swapped and I had an elbow go on me and I replaced it now I've got a hose that has a leak so I'm just going to swap them all. Much appreciated

 

I'm not sure what size of hose your 2002 lighting uses, but I just changed my vacuum hoses on my 1996 F150 Inline6. I did a full post with the site I got my silicone hoses with pics Hope this helps. http://www.ford-trucks.com/forums/14...-4-9-pics.html
