Baby fuel pumps?

What does the GSL395 look like? Have we figured out if fuelpump draw varies depending on load, pressure etc. ? That chart looks like it does.

It seems that all of the pumps listed are the same dimensions.

Certainly current draw will be affected by the pressure, but I still think that the pumps will flow around the same LPH all the time.
The difference being how much is returned to the tank vs how much goes through the injectors. Also, I guess the flow through the injectors in a small application would be very small compared to what is returned.

I recently acquired yet another pump. This is smaller yet and is a WalBro. It was listed as a Harley EFI pump and the WalBro number is R-12973TB. It is not an inline style rather intank but not mounted with a flange. I believe it could be mounted in the tank with the supply hose attached and wires connected and submersed under the fuel. This is similar to how K-model BMW motorcycles were set up in 1985 and probably other years.
