Ran 2 Holley blue pumps in series from 1988-2006. Same pumps and regulator never an issue. Car ran 10.80-10.90 from 1988-2000. Upgraded the engine and got the car down to 10 teens w/the same set up. Only leak I ever had in my fuel system was the big Fram fuel filter.




Why would you run 2 pumps in series and not parallel
