The stock VACUUM activated petcock leaks (common issue)

My 2004 Bandit is now 10 years old (I bought it used in 2009).
It has about 32,000 kms/18,000 miles on the odometer, a Yosh Slip on, K&N Stock replacement filter, (Probely a jet kit) and has run great since I bought it (it had all these mods before).
Pingle does NOT seem to have any thing listed.
What is a viable alternative to replace the stock vacuum with a traditional (on/off/reserve) unit?

i tried that when i was waiting for my new vacuum fuel tap to arrive , bike ran like a sick pig , its not a brilliant idea , rather pay the extra money and go for the standard vacuum tap if yours is giving issues
