All the suppliers seem to state that the 5mm silicone boost pipe is not suitable for fuels, oils etc. Which begs the question what could you use for MAP readings off the inlet manifold? High pressure fuel line?

as theres not really any fuel/ oil in the line you can get away with the silicone stuff ok, somthing ive seen used is the ptfe line and fittings that is used for welding gas, pnumatics etc.

It's only what's connected downstream of the carb's jet you need to worry about, and then only if they flow enough to ingest petrol vapour - what's the volume of a MAP sensor or boost gauge  :D

I've always used 3mm ID vac hose. Never in all the years i've had it on my cars has it ever caused an issue.

Sod it. I've just been using silicone boost/vacuum pipe too. I'm just getting less gun ho and actually started reading things before I buy them. :-)
