I have a 1998 gmc sierra and mt oil pressure gets
Well, they may be right in saying that normal engine wear is causing this problem as the distance between the bearings and the oil passages gets bigger, the oil pressure drops.
If you want to spend the money on a new oil pump, you can, but there is no guarantee that will solve the problem.
You're right, the oil pump's passages might be wearing along with the rest of the engine causing this gradual low oil pressur problem.
Have you had the oil changed along with the filter to see if maybe there's a circulation problem in the engine?
I had low oil pressure on my 1997 Cadillac Deville Limousine, that was intermittently flashing the low oil pressure light.
I read that it's recommended to change the oil to the proper viscosity and that seemed to clear up my problem on my GM Northstar engine.
It's worth a try.
Good luck on this repair.

Power steering hoses are made to withstand very high hydraulic pressures.
They are assembled with equipment made to do that which is impractical for a home-owner or even most shops to buy.
Your only two options in your case are either to buy a replacement hose (pre assembled) or to have a specialty shop (usually large machine shops that do work for heavy equipment or farm vehicles offer that service) make you a new hose.
Anything you try at home will quickly blow apart.

I have a '97 Chevy Silverado 2wd, auto trans, 5.7,
THE CODES AND THE DEFINITIONS:
P0134 - Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 1 Sensor
P0135 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 1
P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1
These codes mean that the oxygen sensor in the bank one # one cylinder side of the engine is not working properly, I suggest u replace the Bank one sensor one O2 sensor.
The bank one sensor is located in the exhaust pipe before the catalytic converter on the right bank of the engine (this is once again the bank that contains cylinder #1) as u stand in front of the truck, it takes a 7/8" wrench to remove. replace the sensor with a GM sensor, aftermarket sensors can trigger more codes and are no cheaper than the OEM sensor from GM parts. Below u can find a diagram of the cylinder layout, as u can see bank one is on the right.

this DTC determines,if the distributor is installed incorrectly,or if there is a mechanical malfunction in the engine.
check the following items
A loose or missing distributor hold down bolt
A loose CMP sensor causing a variance in the sensor signal
Incorrectly Installed distributor-1 tooth off in either advance or ****** positions
Aloose distributor rotor on the distributor shaft
excessive free play in the timing chain and gear assembly.
