What about heat from both pumps being on all the time. My fuel gets hot after a long ride with both pumps on all the time. I mean hot. I'm getting ready to change over to the hobbs switch to control the second pump to see if I can't keep my fuel a little cooler.
30K plus miles on a turbo car with no issues like this. Stock GT500 setup has pumps running while the car is....so whats the difference?
