Does the 12v 4.5-7psi pump have a check valve so fuel can only flow in one direction?

Yes, this fuel pump has only one check valve and fuel can only flow in one direction.

Anyone find the male end for the electric connection? What do you search

There should be a mating plug on the 02A car. If there is no mating plug, you can cut off the plug and connect red to positive and black to negative.

Can i use the 2.5-4.5 psi model to add an external fuel tank to a gravity fed 3400w generator? will it flood the carburetor?

This pump output pressure is 4.5-7psi,so you can't use this model.But you can buy another pump that is E8016S in our shop, which can add an external fuel tank to a gravity fed 3400w generator.

Do not buy as it does not work.

Does not suck. AT ALL! Tested under the most favorable conditions and it spit diesel. Container above pump while rotating through 12v 2amp/10amp. Pressurized tank to aid in air clearing. Would not work. Wasted a whole day.
