My pump is like this

it's the static advance mechanism i believe it's called . .

that pictured one appears to be ecu controlled at a guess . .or maybe not lol

Cold start advance solenoid - seems to be on older bosch pumps, I'm surprised the 405 one doesn't have it tbh. All it does it advance the timing a little to make cold starts a bit easier

Nothing to worry about.

Its for the load dependant timing. Makes no odds tbh, the are both exactly the same performance, but one with the blank off causes slightly noisier cruising speeds because it maintains rpm/advance curve where as the one with the pipe backs off the advance depending on how far your foot is mashed.
