I understand the hose will not work with E-85, but is the regulator itself E-85 safe?

Hi, the regulator compatible with E-85.

Is the fuel pressure regulator E85 compatible?

no, the stainless steel braided CPE fuel line can't be used for E85.

How does the gauge mount? Can it be remotely mount?

There is one 1/8" NPT gauge port on the front, apply some thread sealant to the thread, and install the pressure gauge on the regulator.

Hi can i use this on a 4g93 gdi engine?

Hi, the adjustable fuel pressure of the regulator is 30psi -70psi. It can be used as long as the pressure is adjusted to meet your needs.
