If the entire fuel tank was replaced, then the fuel pump and filter were removed. You might want to check those two spots for vacuum leaks. Pull the rear seat bottom cushion and check that both have good o-ring seals.

I would take it back to whoever replaced the fuel tank and tell them to fix it properly, since they didn't.
