Fuel Leak Fixed on Infiniti G35 Coupe

In the end of the previous post, we ended up with a fuel leak on the 2005 Infiniti G35 Coupe after trying to fix the fuel sensor issue. The car was towed to the dealer, who after keeping it for 10 days and quoting an exorbitant price of over $3000 to fix the fuel leak, did nothing to the car besides fixing a seat belt recall. I ended up losing $200 on the whole and got the car towed back home. Then with help from the g35driver.com forum post and the service manual’s Fuel System section I diagnosed the problem to be loose fuel pump cover bolts and bad O-rings.

Once I purchased the replacement parts from a local Infiniti dealership, I was able to fix the leak. This post describes what I did wrong, and what one should take care of when handling the fuel sensors.

Fuel Level Sensor Issues on Infiniti G35 Coupe

The 2005 Infiniti G35 Coupe came with a check engine light (CEL) code of P0462 (Figure 1). The fuel gauge always showed empty and I watched a few Youtube videos on how to clean the two fuel level sensors below the rear seats in the car to fix the problem. Apparently, after a while the fuel level sensors tend to collect grime over themselves that leads to the fuel gauge reading a zero value.

This post describes that process to clean it out. However, it turns out that the previous owner did try the same process, as the fuel level sensors were already clean. So this meant that the issue was probably the sensor electrical connection or the dashboard fuel gauge itself. I did the fuel level sensor cleaning/checking on August 3rd, and on August 10th (today) I filled up the tank fully. But it was a disaster. The fuel tank was leaking non-stop (Figures 25 and 26) and so I had to accept my limited abilities at this point and got the car towed to the dealer. The dealer wants me to install a new fuel tank since the current one is dented and has too much rust. 😞

Anyway, this post still describes the fuel level sensor cleaning in case you may benefit from it.

Replacing Air and Cabin Filter on the Boxster

Since buying the Porsche Boxster S, I had driven it for at least a 1000 miles in the last 2 years. However, I had never changed the air filter or the cabin filter. The Boxster was sitting for a few weeks in a dusty area in Texas before I got it, so I decided to do this change and reduce the smelliness in the cabin as well.

This is one of the easier changes to do in the Boxster and requires no tools. I recommend purchasing the Hengst Air Filter E458L (Figure 14) and Hengst Cabin Filter E951LC (Figure 17) for this task. These are the OEM filters that Porsche uses on the 986 model cars and it is best to stick to OEM versions for a perfect fit.

Aluminum Skidplate Install on the Infiniti G35 Coupe

While doing the oil change on the G35 Coupe, I realized like several other folks on the internet, that the plastic skidplate or undershroud gets in the way of taking off the oil filter (Figure 1a). The plastic skidplate breaks after a while and mine was cracked and damaged. The bolts holding it were rusted too. I saw someone on reddit install an aluminum skidplate, so I bought one on eBay for $115 and decided to install it. The installation is really easy.

New tires for the Porsche Boxster S

While swapping the winter wheels and tires back to summer wheels, I discovered my rear tires were really bald (Figure 1) on the inside portion. This meant the car had a bad alignment and it needed new tires.

I ended up getting new tires for the car as I had a TireRack gift card, and the prices of tires there were much cheaper.

For the Boxster with stock OEM wheels you need 205/50ZR17 (Figure 3) for the front wheels and 255/40ZR17 (Figure 4). I purchased the Riken Raptor ZR A/S (all season) tires with these specifications.
