Hey guys, I'm looking for opinions with this one.
After an extended dyno session, warm day, my fuel pump was making more noise. I would state same type of noise, but louder.
Performance was unchanged, but obviously I need to chase this.
I will look at usual suspects, but it occurred to me that I read about fuel pumps making more noise with hot fuel. Can this be true? Cavitation? Pre-vapor lock?
The tank was 3/4 full, so level was not low at all.
The stock fuel cooler is essentially inert since I have deleted the a/c.
This is another angle I did not appreciate ahead of time.
Running a stock fuel pump, based on mathematics with the low boost SC, I didn't see the need to upgrade to a Bosch 044 pump, but i could certainly add an inline cooler without a lot of effort.
Thanks.
