G'day mate and welcome to the forum!
The handle on the left is the Fuel shut off lever, the right hand one was the Fuel hand pump, as you said.
C and D versions had an extra handle above the Fuel shut off lever (or Fuel c0ck), which was the Coolant radiator flap handle. Though this also appears in a drawing I have of an E-3 dash, it dosen't appear in photos, so I believe the latter!
Colours in colour photos I have:
Bf109E-1, DTM, Munich. RLM 66 cockpit. White Fuel c0ck, Yellow hand pump (cockpit unrestored, original colours)
Bf109E-4, BoB Museum, Hendon. RLM 02 cockpit. Yellow fuel c0ck, Yellow hand pump. (restored cockpit, unknown how correct)
Probably have more around in the stash, will post details if I find them.
(Btw, had to rewrite fuel 'c0ck' like that, as the computer thought I was swearing and censored the word!
)
