electric fuel pumps

Does anyone know of a source for a 6V elec. fuel  pump with less than 4.5# pressure rating?

Ken - National chains such as AutoZone, O'Reillys's, NAPA, and Advance/PartsOne have web sites where you can ask about parts. They all have listings (although limited) back to 1944. I suspect the software & database are related on all these sites. If they don't have a listing for Kaiser or Frazer with a 226 engine, look for 54-61 Willys station wagons.
After seeing your request, I went to AutoZone and asked for a fuel pump for a 1950 Studebaker Champion. It showed only 1 electric fuel pump Airtex Master E8011 and I wasn't happy with the price. 2 years ago when I did such an inquiry, there were 4 part numbers (there are several different yet popular electric fuel pump designs). All of these worked on 6V and polarity (-  or + ground) wasn't a problem.
If you find a fuel pump available at one of these national chains, you can try going to the manufacturer's site and see if they have more specifications which in your case would be the rated psi.

I've been able to find some on ebay.  And you have to be very careful as there are some that will not permit fuel flow-through with the pump off. Also, unlike in the past at least the solid state type will not operate on + ground, so you have to hook them up to the battery/car as normal today, i.e., - ground. They bellows type seem to be being phased out due to the problems of the internal rubber parts with ethanol. I have used an AC Delco type similar to the E8011 but I just looked on my '54 Late Special and it's a 6V pump from Mac's antique auto...off ebay about $50.

Car Quest has the 8011, I also bought a pressure regulator to reduce gas flow
