How much peak HP you are making will determine how many GPM you will need. You can rig the CV Products FP without a regulator up to 750 HP (green spring) but it is pretty pricey. You can spend less than 1/2 the price of a CV if you are in the 500 HP range. Hardin Marine should have what you need.

Any recommendations for a more reliable "Sea Water pump mounted" fuel pump to replace the standard HP 500 EFI Merc units. The Mercury design diaphrams have a short service life.
