Does anyone know what is the lowest psi electric fuel pump?

I need to mount a tank lower than the carb on my 8hp Briggs,it is gravity fed . My ZTR has a diaphragm pump off one of the cylinders, don`t think that that would work on this old L-head . My question is ,does anyone know what is the lowest psi electric fuel pump? I am pretty sure that it can`t handle very high pressures without flooding the engine.

I've heard of people running vacuum lines for diaphram fuel pumps on single cyl engines from the dipstick tube. Dont know how well this would work. The crankcase vreather is the other obvious choice I think? But dont quote me on that lol!

Thanks ! I had not thought of taking it off the dipstick tube. I will look into the parts for that. study
