Hi
What does this little pot do on the top of the engine?
gets the dribble from the injectors on this perkins engined 2A.
there is a brass thing on top and a pipe to the tank and one to the inlet manifold-thanks in anticipation of shared wisdom.

Looks like a swirl pot, or pressure regulator. Or could be a spill return from the IP.

Is there a return to the tank?
 
Hot start, basically you hold the key against spring pressure, this activates a coil that gets red hot then some diesel is allowed to run across the coil, this catches fire and voila early glow plugs!
But I notice you have no wire on the glow unit itself.

Gosh- i will have a look for some cables... the wiring was such a mess- 90% has been stripped out and there may be something like that.
 
Very similar system to early Transits.
On really cold days when Diesel would 'jellyfi' the fitter would soak a rag in diesel and use a welding rod to stuff it down the intake whilst we turned it over. And I should mention he set light to it ! Not just a wet rag ;)
Happy Days :)

Feeds the cold start aid screwed into the inlet tract. Get it going, I have had several, on Perkins engined tractors and Land Rovers.
Better than glow plugs, and don't put so much load on the battery in cold weather.
