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.
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...
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.
