Replaced the fuel pump and EGR, it is still hesitating when RPMs get over 2000?
What is your question?
Is there another fuel pump or fuel sensor somewhere? It runs fine as long as I don't let the RPM's get above 2000.
My truck is a 5 speed...
Please help ...

Sounds like a restricted catalytic converter. Its choking the motor by not letting exhaust escape fast enough at higher rpms. Just a guess with the limited info at hand
