( should have just changed my filter ) my two cents . Between my flywheel / clutch "upgrade " and this my new moto is if it ain't broke don't fix it lol . The problem of only improving one point of a stock system is the rest doesn't work together well . If you put in a lower bar fuel pressure gauge to make an aftermarket pump happy then you have to adjust the tune . It's a slippery slope .

For an >1200whp S38 turbo car that my mechanic built in his days, he had a stock fuel pump feeding a fuel catch system and 2 external Bosch 044 feeding the fuel rail. (just a remark, not an argument)

I think we're good with the stock fuel pump. Thanks a lot for your constant feedback, i just cancelled my order of aeromotive fuel pump just because of this thread and your feedback.
