The carter hv pumps 120gph 6-8 psi. I used it on my 540 with a 950 holley. I know several people that run them on there blower motors.

Try here. You didn't say whether they were on your blocks or sea water pumps. The levers are different.

I had no problems with my 1050 Dominator.

Merc uses the stock carter on the 525SC to feed a 1050. Same part# for my 454 mags or for 525SC.

Got the Carters on my 540's with 1050 Dominators and FP guages on the dash...Pressure never varies from idle to WOT. Except once when something was stuck in the needle and not sealing and at an idle it was down about 1 lb and pulsing with each pump of the diaphragm . Meantime I'm dumping gas down the back barrels

Any car parts store has the same ones Cp Performance sells at twice the money. What you do is use the top part of the Merc pump and replace the bottom with the Carter HV. This is the same thing CP sells you.
