On a test run at battery voltage, each pump flowed just over 4.5qts. on an individual 30sec test & together flowed just over 9qts in 30sec.
Unsure how much fuel was pulling across from the Venturi, as I didn’t have a separate reservoir setup with tube installed.

XRP’s big bore HS-79 hoses are very light & flexible in the -8 size

Well done installation. That HS-79 probably ran you more than the pump hanger Its nice stuff indeed.
