No.
Assuming this is a 4.3L engine, the fuel pressure regulator is located under the upper intake manifold. The upper intake manifold must be removed to gain access to the regulator.
On the poppet bank under the upper intake manifold.
On the 4.3 engine it is located under the upper intake manifold. The upper intake manifold must be removed to gain access to it.
It is under the upper intake manifold, attached to the bank of poppets.
The 98 Blazer with a 4.3L V6 fuel pressure regulator would be located under the upper intake manifold. It would be attached to the bank of fuel injector poppets aka "the spider". The upper intake manifold would have to be removed to gain access.
4.3L fuel pressure regulator is under the upper intake manifold. It is attached to the fuel injector bank.
The intake manifold is to the right of the valve covers. The throttle body attaches to it. If that is what you are talking about then that is the Plenium. the plenium attaches to the intake manifold right beneath it.
Assuming you have the 4.3L engine it would be located under the upper intake manifold. After removing the upper intake manifold you will see the fuel pressure regulator attached to the bank of injector "poppets".
It is attached to the bank of fuel injectors (the spider) under the upper intake manifold.
A 4.3L engine has the fuel pressure regulator located under the upper intake manifold attached to the bank of fuel injector poppets.
If your engine is a 4.3L V-6 with CPI (central point injection) it is inside the upper intake manifold. The upper intake manifold is bolted on top of the normal intake manifold. The throttle body is mounted on it and your fuel lines terminate into the center of this.
The fuel pressure regulator woiuld be located under the upper intake manifold on a 4.3L. It is attached to the bank of injector poppets aka "the spider".
