I have an Eldebrock mechanical fuel pump that creates 10psi. I only need 6psi to run 3 dueces. I put a adjustable fuel pressure regulator in place. My question is should would it be better to get a mechanical fuel pump that produces 5 or 6 psi than reduce it down this way? Are there any takeaways short/long term on the 10psi fuel pump being reduced down like this. Thanks.
