Factory Bosch Carb Fuel Pump for PMO 46 Install?

[Super90]

Will the factory Bosch fuel pump for carbs on my 1970T (Zenith carbs from the factory) support PMO 46s for my 3.2 motor install?

Anyone know the delivery rate (gallons per minute) and pressures that it produces and will that support the PMO 46s ? I am under the impression it will.

EDIT: Found this in the factory data showing that pump delivers 21 gallons per hour. Wonder what the PMO 46s require.

Thanks !

So, looks like I am slowly finding the answers to these questions. Many thanks to Mr. Paul Abbott of Performance Oriented, once again.

Per his website and a quick email, one needs 0.1 gallons/hour of fuel delivery per horsepower. So, if the 3.2 at 10.5 compression ratio, twin plugged, puts out, say 250hp (hoping for more obviously!), we would need 25 gal/hr of fuel supply.

Looks like we would be short at 21 gal/hr from the factory pump.

Hope this helps someone.

If a person drives at 60 mph for 1 hour and uses 25 gallons of fuel this would be 2.4 miles per gallon . Something is wrong , I don't think a 3.2 could use this much fuel .

I think the calculation is more about what it takes to provide enough fuel to the system at WOT for some time. Maybe just a few minutes. I am not under the impression it is about WOT for a full hour. Its that fuel delivery rates are typically quoted at gallons or liters per hour because that is easier to relate to instead of fractions of a gallon or liters per minute.

If the pump cannot supply fuel at a sufficient rate, you wont be able to drive at WOT for even a minute or two. That's my interpretation.
