I was wonder if my 1995 Chevrolet S10 Blazer LT 4.3L have a spider injector?

I don't know if I have Reman or not in there right now. But some people at work said they are good brand and some of them said it isn't a good brand. So I don't know but isn't order nothing until I get the numbers when I do the fuel pressure gauge test this weekend.

1995 CMFI:
The fuel pressure test port is next to the distributor on a 3/8" steel line attached to the rear of the engine. This image is a CSFI engine, but yours is located very similar:

1) Key ON, engine OFF, fuel pump running, pressure must be 55psi to 61psi.
2) It must remain above 50psi for at least 10 minutes after the pump shuts off.
The results of these tests will tell if the fuel delivery system is working properly or not. If there's a problem, it does NOT tell you what the problem is. If it does not pass both of these tests, further diagnosis is necessary to determine what the problem is.

The fuel delivery system is working properly.
The fuel pump relay is energiziging the fuel pump as it should.
The fuel pump is able to deliver sufficient pressure to the injector.
The fuel pressure regulator is regulating at the proper pressure.
The system is able to hold pressure sufficiently.
The fuel injector is not leaking.
The fuel pressure regulator is not leaking.
The lines inside the plenum are not leaking.
There are no restrictions in the fuel lines.

It only hesitation while accelerating easy the first 8 miles of the day when acclercate easy or taking off from the stop sign. But it don't do it when floor it to the floor only when holding your speed or slow accelerating.
