Mancini shows SB mech pumps - one street and one strip.

Also with the Carter versions MP used to sell a coated fuel pump eccentric that they recommended to be used with it. Not sure if they still sell those, or if they are needed?
I know someone with a very modest 408 who runs low 12's still using a parts store stock replacement fuel pump and the factory 5/16" fuel lines. See lots of guys who run around that zone or slower who have huge fuel lines and race spec electric pumps that they don't even need most likely. It's like ignition parts - people go crazy buying next level stuff they don't need before they tap out what they have.
