Default Power loss

Hi
I have an 82 corvette, recently especially when I'm driving uphill, the engine is kind of shattering, between 2000rpm to 3000rpm, and I can see on the tachometer that the rpm is unstable....
On a flat road it feels less, (but it's there.....)
Could it be the fuel pump or fuel filter?

Tnx
Rani

I have 87000m, the engine is in very good condition, I'll try to clean the fuel system before I'm replacing pumps and stuff.....

What is your fuel pressure set to? You need to know that before doing anything really.
