Thousands of years ago, the "hot setup" as espoused by another forum was to replace the TBI pump with the ACDelco EP241. Supposedly "fixed" all sorts of problems with the TBI pump.
I crammed the '241 into my '88. Been there for years. Works great. Downside is the pump outlet is not the same size as the TBI pump outlet, so the hose connecting the pump to the rest of the hanger tubing gets stressed some. There is no concern at all about the OEM regulator being able to control fuel pressure.
I'd use the Vortec pump if I were doing that job again. Hopefully, the pump outlet size is the same as the hanger tube size, so the hose is a simple fit. Use "Fuel Injection" clamps instead of those hateful non-shielded worm-gear disasters. And the hose itself is "special" because it's rated for submerged-in-gasoline use.

If your fuel pumps are only lasting a couple of years, SOMETHING ELSE IS WRONG.
1. I always install an in-tank wire harness to replace the (typically corroded) wires inside the tank.

The new harness is often "generously" sized. It's like spark plug wire kits--the replacement wires are always longer than the OEM wires.

2. Always clean the inside of the tank. Contamination--rust particles, dirt, grit, and water--are the leading cause of in-tank fuel pump failure. And always install a new filter sock on the new pump.

3. I refuse to replace an in-tank fuel pump without verifying AT LEAST the voltage supply to the pump, as close to the pump as practical; and verify the voltage on the ground wire as close to the pump as practical, WITH THE PUMP RUNNING (assuming it runs at all.) Better still is to verify voltage AND amperage draw. And the best-possible diagnosis is to use a low-amperage probe connected to an oscilloscope, which then allows you to examine the current draw of
each individual bar on the fuel pump motor armature, and calculate the fuel pump RPM.
Low supply voltage--or high resistance on the ground side--makes the fuel pump motor run slowly, reduces fuel pressure, and in general is bad for the fuel pump.
4. New fuel filter with a new fuel pump. Restriction in the fuel supply makes life hard on the pump, causing excess wear and higher operating temperature.
