My '52 WRX engine rebuild has got to the stage of Inlet manifold pipes etc.

The complex pipe in this picture is damaged:



I have found a replacement in re-inforced silicone from these folks:

Has anyone any experience of these parts?

Also there are three other rubber pipes as in these pictures:





Does anyone know of silicone replacements for these? The originals are in OK condition but it would be good to match up the colours (blue) as well as finish off the job properly.

I have avoided taking off the fuel lines since I don't propose to change the injectors although reading through the forums changing the fuel lines/rails/ injectors does seem a common practice.

The engine rebuild has just a 'refresh' of a 150,000 miler which I have had from new. It's already had a RCM stainless header and up-pipe and I have a Hayward and Scott single cat system waiting to go in. Original turbo but larger fuel pump and air filter.

Any comments and help gratefully received, thanks
