What mechanical fuel pumps are you guys running?

Why do you want 3/8 ports? Do you know how big that is? 1/4" NPT is plenty big.

3/8 npt is standard for most of holleys regulators - 12-841 is the part number I run on my racecar. Like to keep similar setups on multiple cars so they are easier to troubleshoot
