Five-fuse explosion that's gushing forth (8)

I believe the answer is:

effusive

I'm a little stuck... Click here to teach me more about this clue!

'gushing forth' is the definition.
'effusive' can be an answer for 'gushing' (I've seen this in another clue). I'm unsure of the 'forth' bit.

'five-fuse explosion' is the wordplay.
'explosion' is an anagram indicator.
'five'+'fuse'='fivefuse'
'fivefuse' with letters rearranged gives 'EFFUSIVE'.

'that's' acts as a link.

Can you help me to learn more?

(Other definitions for effusive that I've seen before include "Two-wheeler" , "(Of person) gushing" , "lyrical" , "Pouring out words" , "Gushingly emotive" .)

I've seen this clue in The Globe and Mail.
