Here's a breakdown of how to check your fuel lines, keeping in mind that some aspects will require mechanical aptitude and potentially specialized tools:
1. Visual Inspection:
* Locate the Fuel Lines: Start by identifying the fuel lines. They run from the fuel tank, through the fuel pump (located in the tank), and to the fuel rail on the engine. Consult a repair manual specific to your 1995 Subaru Legacy GT for precise locations. These manuals often have diagrams.
* Look for Leaks: Carefully examine the entire length of the fuel lines, including the connections. Look for cracks, corrosion, bulges, or any signs of fuel leakage (wetness, staining, or fuel smell). Pay close attention to the connections (clamps, fittings).
* Check for Damage: Look for any signs of rubbing against the chassis, suspension components, or other parts that could cause damage or abrasion.
2. Pressure Test (Advanced):
This is the most thorough way to check for leaks, but requires specialized tools. Do not attempt this unless you have experience working with fuel systems. Improperly performing a pressure test can be dangerous.
* Fuel Pressure Gauge: You'll need a fuel pressure gauge that's compatible with your Subaru's fuel system. These gauges typically connect to a Schrader valve (similar to a tire valve) located on the fuel rail.
* Procedure: The procedure involves disconnecting the fuel pump's power, using the gauge to check the fuel pressure within the system, and observing pressure loss over time. A significant pressure drop indicates a leak. The specifics of this procedure are in your repair manual.
3. Checking the Fuel Pump (Indirectly related but important):
A faulty fuel pump can manifest as problems that *seem* like fuel line issues.
* Listen for the pump: Turn the ignition key to the "ON" position (don't start the engine). You should hear the fuel pump prime for a few seconds. If you don't hear it, the pump might be faulty, preventing fuel from reaching the lines.
* Check Fuel Pressure (as above): Low or no fuel pressure also points to a fuel pump problem.
4. Addressing Issues:
* Minor Leaks: Small leaks might be repairable with specialized fuel line sealant or by tightening clamps.
* Significant Leaks or Damage: Leaking or severely damaged fuel lines require replacement. This is a job best left to experienced mechanics unless you're comfortable working with fuel systems. Improper repair could lead to a fire hazard.
Important Considerations:
* Repair Manual: Obtain a repair manual specific to your 1995 Subaru Legacy GT. It will provide diagrams, specifications, and detailed procedures for working on the fuel system.
* Safety: Prioritize safety. Work in a well-ventilated area, use appropriate safety glasses, and have a fire extinguisher readily available. Never smoke near the vehicle.
If you're unsure about any part of this process, it's best to take your Subaru to a qualified mechanic. Working on the fuel system is complex and potentially dangerous if not done correctly.
