ashwinearl Posted September 16, 2019 Share Posted September 16, 2019 Is this typical? I am putting in a boost gauge and tapping into the hose at the front at the manifold by the round foam thing. The original hose from the foam piece to the manifold nipple broke while I was manipulating it. It was rock hard and brittle. 155k miles on a 2005 LGT wagon. I'm wondering what other pieces are hard/brittle. Is this when people switch all the lines over to silicon vacuum lines? Link to comment Share on other sites More sharing options...
Infosecdad Posted September 16, 2019 Share Posted September 16, 2019 That’s “normal” for ~15 yr old rubber. It’s basically porcelain now. I addressed it by buying a bunch of 4, 6, & 8mm silicon hose from Amazon. Link to comment Share on other sites More sharing options...
