Made 2 holes in the Jam Jar lid and inserted hose (used tape to cover holes), connected pump to one length of hose with lots of tape, removed air filter box\maf and inserted other length of hose down the pipe, blocked up hole with t-shirt to prevent smoke coming out, lit pellet and placed in jar, added lid and switched on pump. the smoke was then forced out of the hose into the air install pipe and as it happens can out the split pipe. Becareful the jar gets very hot.

And I must admit, I did do the happy dance in the garden when I saw smoke coming out of the split pipe.
