Replacing a Fuel Pump (Honda Civic 1999)!

My 1999 honda civic still has its original fuel pump. I have had problems of the engine not starting on mornings when I remote start. As part of my proactive replacement program I decided the replace the pump with a denso pump from Amazon.com.

Read on for how I did this replacement job.

Removing the Backseat.

The backseat is held by a 10mm bolt that is off Centre to the left between the base and back paddings. Once the backseat is out the fuel pump and gauge are fully accessible.

Accessing the Pump Assembly.

There is a cover held by 4 Phillips head screws that protects the pump and gauge. Once off I unplugged the fuel pump electrical connector and disconnected the 2 fuel lines. The fuel line with the special connect is a little tricky but the yellow tabs needs to be squeezed and the line rotated a bit and pulled apart.

The pump assembly is held by nuts and I used my Ratchet and socket to remove all and set them aside.

Removing the Pump Assembly.

Carefully sliding the assembly out at an angle the entire unit was now out. I put it on a rag on the trunk lid.

Taking Out the Old Strainer and Pump.

Taking off the electrical connector and hose clamps I proceeded to remove the strainer. The tiny spring clamp has to come off first. I used a flat blade screwdriver to do that. Next the plastic strainer came off and the pump itself I levered out.

The denso replacement is identical to the oem.

Assembling the New Pump and Strainer.

The new piece of house I slid onto the put first then onto the discharge tubing. The retaining clip for the strainer was a pain to get in properly.

Making sure everything was in place as it should be I went onto the next step.

Putting the Pump Into the Tank.

I slid the assembly carefully into the tank. Next I bolted up the cover and reinstated the 2 fuel hoses.

Testing and Checking for Leaks.

After plugging back the electrical connector, I put a piece of paper towel under the discharge line. I put the car key onto the position right before starting the engine to make the pump active for 2 seconds. I did this 4 times and checked the paper towel for gasoline stains each time. Happy there are no leaks I went ahead to complete the works.

Completion.

Once I put back the cover on the pump and gauge Bay, the backseat went back on and now the car runs well with a brand new pump!
