The real governing factor is if you have too much pressure it will overcome the needle and seat and flooding will occur.
Those pulse or solenoid pumps are available in the under 5 psi range

I've read somewhere that I will be able to run a 12 volts electric pump at 6 volts so it will be easier to find a near perfect match, unless you have a company name and part number that would work just fine for this application. Thanks.
I would be buying a low pressure 6 Volt Fuel Pump. You can run 12 volt pumps on 6 (at least some of them), but it is a crapshoot as to what your results will be as to PSI.
Consider something like this: www.macsautoparts.com/ford_mercury_early...ord-and-mercury.html

If you are interested send me a PM with your number, I'll give you a call.
The bitterness of poor quality remains long after the sweetness of low price is forgotten.
Be of Good Cheer
