Well by your question...im guessing you have the HPFP. To tell what GPH you have you need to look at the motor and motor block. Then compair to the following:
EM-1001 with "A" Block = 150 GPH
EM-1001 with "B" Block = 95 GPH
EM-1002 with "A" Block = 200 GPH
EM-1002 with "B" Block = 120 GPH (90 @45 PSI)
EM-1002 with "C" Block = 240 GPH
As for converting the HPFP to a FASS....we dont offer a kit for that conversion. We getting the FASS, using only what you need in the kit and then sell the HPFP with the unused items in the FASS kit to give it a new install kit per se.
