Did you also replace the fuel filter?
Sounds like you may have already but wanted to confirm.
The instructions for replacing the filter are below.
I would advise when you have the the old filter removed try blowing back through in reverse direction into a container and seeing how contaminated the fuel entering was.
How did the inside of the tank look when you replaced the pump?
