[TR6 radiator drainage vlave]

I have acquired a new (old stock) radiator with no drain valve fitting (and no valve).Why is this ?  and how are you supposed to drain the system ?

[TR4a Brake servo vacuum connection]

I have a '67 TR4a with the factory fitted vacuum oil vent valve on top of the rocker cover.This connects to the intake manifold,the idea being to draw the oil fumes into the engine.Fine.

But where can I connect my new aftermarket brake servo ? I'm wary of merely fitting a T peice to the manifold vacuum connection because this is designed to suck in oily fumes from the rocker cover and therefore it won't provide the full vacuum effect for the servo (and might contaminate the servo diaphragm ?).Help please !

[AC fuel pump]

Does anyone know how to remove and replace the flow valves in the AC fuel pump fitted to a '67 TR4a.They seem to be held in place by 6 small punched deformations around each valve but I've no idea how to remove these to change the valves and then how to secure the new ones.

Or should I just give up and send back the rebuild kit and buy a replacement pump ?
