Be careful on the psi vs hp rating. If you boost reference a turbo car with a base fuel pressure of 58psi....then add 20 lbs of boost...the flow rate tumbles for two Walbros at 78psi.Less than 600lbs/hr for two Walbros over 78psi vs 740lbs/hr for two 044 Bosch pumps at the same pressure. Two Walbros at 50psi are almost good for 800lbs/hr.

Yes, gasoline only. No methanol, I don't use it on any of our cars.
Dual walbros, stock feed line and filter. Upgraded rails, adjustable FPR (mounted up front), stock evap line used as return.
