Use of silicone hoses

[stevefh]

Hi all, those of you who are using silicone hose in your induction and purge canister systems have you had any problems with your lambda sensor due to silicone contamination. I started to think about this when deciding whether to make replacements for the rubber connectors in the vacuum system ,that continually split, out of silicone .Has anyone made successful replacements? Will 2.5 mm I/d stretch to 4+ mm I/d in silicone ?

In general silicone hoses are not fuel resistant. If you renew the hoses for the purge cannister system use some good quality fuel hose.

For the vacuum system you can use silicone hoses.
