Instead of rebuilding, you should replace the fuel pressure regulator. This is a relatively straightforward repair, though it does involve working with fuel, so safety precautions are crucial. Here's a general outline:
Before you begin:
* Safety First: Disconnect the negative battery terminal. Fuel is highly flammable. Work in a well-ventilated area, away from any open flames or sparks. Wear safety glasses.
* Gather Supplies: You'll need the replacement fuel pressure regulator, new fuel lines (if necessary, depending on the condition of the old ones), wrenches (sizes will vary depending on your truck), and possibly some rags or shop towels.
Replacement Procedure (General Steps - Consult a Repair Manual for Specifics):
1. Locate the Fuel Pressure Regulator: This is usually mounted on the fuel rail. Consult your vehicle's repair manual for the precise location.
2. Relief Pressure: Before disconnecting any fuel lines, relieve pressure in the fuel system. This is usually done by starting the engine and letting it run until it stalls (due to the lack of fuel pressure after disconnecting the lines). Or, there might be a bleed valve on the fuel rail. Again, your repair manual will give you the proper method.
3. Disconnect Fuel Lines: Carefully disconnect the fuel lines from the regulator. Have rags ready to absorb any spilled fuel. Be extremely cautious as fuel under pressure can spray.
4. Disconnect Electrical Connector (if applicable): Some regulators have an electrical connector. Disconnect it carefully.
5. Remove the Regulator: Use the appropriate wrenches to remove the regulator from the fuel rail.
6. Install New Regulator: Install the new fuel pressure regulator, ensuring it's properly seated.
7. Reconnect Fuel Lines and Electrical Connector: Carefully reconnect the fuel lines and electrical connector.
8. Reconnect Battery: Reconnect the negative battery terminal.
9. Check for Leaks: Check all connections for leaks.
10. Start the Engine: Start the engine and check for any problems.
Important Considerations:
* Repair Manual: A repair manual specific to your 1995 Chevy Silverado is highly recommended. It will provide detailed instructions, diagrams, and torque specifications for your particular model.
* Professional Help: If you're not comfortable working on your fuel system, take your vehicle to a qualified mechanic. Incorrectly working on the fuel system can be dangerous.
This information is for general guidance only. Always consult your vehicle's repair manual for specific procedures and safety precautions. Improper repair can lead to engine damage or even fire.
