You're still getting air in somewhere.

Loose hose. Bad connection. Cracked old hose. Bad o-ring

Did you change all hoses?
Did you use the correct size hose?
Did you use Toyota hose clamps? Or cheap worm drive clamps?

Are both o-rings on the filter good? If not lubed when installing the filter they can twist and deform.
