Wrong ones. The ones I'm referring to are the ones used in OEM fuel collectors. They run well for years. I'll try and find an example already in production and available.

As far as the second fuel pump goes, I'd run if off of a relay with the coil connected to a WOT or boost switch. No speed controller needed.
