My pickup has a hydraulic clutch that I had to "re-engineer". Just about
every thing on it is plastic. master cylinder, slave cylinder, and the
lines. And the line is NOT reinforced plastic. It is just a poly type
plastic hose. I have it spliced with just a standard plastic airline
fitting.
There is not that much pressure in the hydraulic clutch system to worry
about line expansion.
I would suspect that you have a high spot in the system that is trapping
the air. the bleeder valve should be the highest point.
