* Silicone Vacuum Hose: While not a direct replacement, high-quality silicone vacuum hose is often a very suitable substitute, especially for the smaller diameter sections. Silicone is highly resistant to heat and chemicals, and it's flexible enough to work around the engine bay. You may need to use clamps to secure it.
* Steel Tubing: This is the most durable and long-lasting solution. You'll need to carefully measure the existing lines, and possibly fabricate new sections using steel tubing of appropriate diameter. This requires some fabrication skills and the right tools (pipe cutter, flaring tool, possibly a bender depending on the curves).
* Replacement EGR Pipe Kit: Your best bet might be to find a replacement EGR pipe kit specifically designed for your 1995 Dodge Ram 1500. These kits are often available from auto parts stores or online retailers. This will ensure proper fit and materials.
* Combination Approach: You could use a combination of silicone hose and steel tubing. Use steel for the higher-heat, higher-pressure sections and silicone for the less demanding parts.
Important Considerations:
* Heat Resistance: Whatever material you choose MUST be rated for high temperatures. Exhaust gases are very hot.
* Pressure: The EGR system operates under pressure, so make sure your chosen material can withstand that as well.
* Clamps: Use high-quality hose clamps to securely attach any new tubing.
* Proper Fit: Ensure any new piping fits correctly to prevent leaks.
* Correct Routing: Pay close attention to the routing of the original pipework to ensure correct system operation. Improper routing can lead to performance issues.
Before starting any repair, consult a repair manual for your specific vehicle. This will help you identify the exact components and ensure you replace everything correctly. Failing to do so can cause damage to the engine and potentially lead to serious issues.
