Introduction: Replacing a Fuel Return Line.

Picture of Replacing a Fuel Return Line.

Due to the age of my 1999 honda civic, I wanted a fresh fuel return line in the engine bay. The original route consists of two hoses and a hard line at the fuel injectors.

I bought a reel of gasoline rated hose and went to work.

Step 1: Removing the Old Connections.

The hard line was held by two 10mm bolts. Removing those and the hose connections at the fuel pressure regulator and the fuel return line, I put these aside.

Step 2: Making the Connections.

Using stainless steel hose clamps I made the connections at the pressure regulator and the return line. I made sure the clamps were tight.

Step 3: Completion and Testing.

I used a zip tie to secure the loose section of the hose. I started the car and she works just fine now! This new fuel hose line should provide several years of service!
