advise on electric fuel pump

Rail mounted inline pump from a newer Ford pickup. They are Walbro "in tank" style but are exterior mounted. Plenty of volume, must use bypass regulator somewhere in the system. These are the pumps supplied with the Edlebrock (and others) EFI retrofit kits if you choose not to use an in tank unit. Mount them in their foam insulator sock and you can barely hear them. Mercedes used them outside the tank too.
