On Wednesday 6/20/18 I took the Porsche to the track for Track Night in America at NJMP. This is such an awesome experience and I recommend this to anyone who is into cars and high performance driving. It is a low pressure, easy going atmosphere and the Novice groups (which I registered for) was very laid back. I felt quite comfortable going out on track with the group of people I was with and with the instruction that was given.
That being said, this is the second time that I have been to NJMP for Track Night in America. The first time was also a good time and the experience was very low pressure. The first time that I went, I filled up my car on the way down, and then filled it up again when I was close to the track. This allowed me to make it through the sessions without issue or even thinking about fuel.
This time, since I drive a slow, fairly fuel efficient car, I decided to just fill it up on my way down and let it ride. This was fine until my last session where I started having some stuttering issues. I believe it was fuel starvation and was happening on hard right turns. After doing some research, I found that it might be due to the fuel strainer in the tank. This is how you change that!
Use up as much fuel as possible! I cannot stress this enough, I thought I used a lot but when it came time to drain the tank, I had more fuel than expected and had to scramble for additional containers to catch it.
The fuel strainer is located on the passenger side of the car, kind of attached to the fuel tank with a strap.
You will need to remove the strap and the cover to gain access to the fuel strainer. Use a 13mm socket to loosen the bolt that holds the strap in place.
You can then let the strap hang down. Move it out of the way carefully. These cars are old at this point and you don’t have to replace it if you don’t have to.
Now, you can remove the cover for the fuel pump. There is a zip tie that is holding the fuel pump to this cover that I had to cut off. I’m not sure if it was supposed to be like that from the factory but mine was and I put it back with a new zip tie when I was done.
The fuel strainer that is in the tank should now be visible.
You will need to use a flat head screwdriver to remove the hose clamp that is leading to the fuel pump. Loosen the clamp and slide it back so that only the hose is on the strainer.
Have your container ready! Slide the fuel hose off of the in tank fuel strainer. Fuel will come pouring out! Be ready! As stated earlier, there was a lot more fuel in the tank than I anticipated so make sure you have enough container capacity. You can always slide the hose back on and look for more containers if you have to.
Once all of the fuel has been drained out, use a deep socket 17mm to remove the in tank strainer.
This is what the old one looked like:
This is the new one! You can see why I was having a problem! This did fix my fuel starvation issue with lower amounts of fuel in the tank. I believe that the filter section holds onto enough fuel to allow the pump to still pick up the fuel while under hard cornering. You can see in the picture that the old one was completely missing is filter elements.
Put the new strainer in, making sure that you use the seal that came with the new strainer. Now put it all back together in reverse order! The only thing that I had an issue with on the installation was getting the strap to get bolted in. I don’t think that I had the cover for the fuel pump on correctly and was struggling. I eventually got it but it was the cover that was the issue, not the strap. Keep that in mind….
