TLA? Not sure what that is?

Fuel pump and filter replaced. Runs like a banshee!

Appears the evap system is deleted. No canister. How do I overcome the vacuum build up? Car didt have any of it when I got it.

TLA = Three Letter Acronym. ;)

My recommendation on the evap system would be to replace what's missing... otherwise you really are just wasting fuel (it does NOTHING to affect power output).
