I have searched and searched for information on just what to do to create necessary baffling in a fuel tank for the use of a tank mounted fuel pump.

I have found nothing

This is what I believe is needed:
1. The baffle needs to hold about 3 seconds use of fuel that would be used in an all out full acceleration.
2. The baffle should employ a design that lets fuel into the baffle but not out, at least not quickly. I am thinking of thin rubber sheets / flappers that work to cover a hole in the baffle on the inside so that fuel presses on the flapper to seal the baffle opening shut.
3. The openings on the baffle need to be close to the bottom so that when the tank is really low on fuel, fuel can enter the baffle with a minimum amount of movement.
4. The tank needs a very low spot for the baffle to sit in so that when the vehicle is not moving, fuel is readily available, even when the vehicle is on an incline (like a steep driveway).

Have I covered all of the bases??
Thanks
