I'd also done a lot of research into the use of electric fuel pumps on military vehicles during the war as a fix to operational problems in hot regions prior to going that route on my own T-16.
The modern pump I ended up using is rated for 4-7psi but this is restricted by the adjustable fuel pressure regulator that I have set at 3.5psi since the wartime manuals mention that pressure in association with the carburator.
Not sure how this equates to actual fuel flow since that would entail math formulas dealing with the pressure and capacity of the fuel lines
