Purge is on driver fender well area.
It has a fairly large vac line coming to it from the engine . It says MOT on top,
When eng is warm , place it in your hand and you should feel it vibrating @ 5/6 times a sec.. Feels like a hearbeat.
They get crap in them and stick.. a trick is to take the line off between the purge and canister and fill it with a few squirts of WD40, rehook it up and the engine vac will suck it through . cleaning the valve in the process...
