Default Model B Fuel Pump

I'm working on my "touring" motor and with the Weber downdraft carb they recommend a fuel pump. I've checked a few places and can't seem to locate one. Any recomondations on locating a pump (32 - 34 )

A 12 volt Holley pump will work fine on 6 volts. In fact it still puts out too much pressure and volumn, so you use a 4 ohm 50 watt resistor to drop it to the correct output. If you use the 12 volt pump with a 12 volt battery, then you need about a 16 ohm resistor. The 12 volt pump will be running on about 2.7 volts, so it takes less current, runs a bit slower, and will last longer.

This is an all metal rotary pump, so it has no diaphram to be damaged by crap gas.

From Snyders website installation instructions for Weber car kit suggest Carter/NAPA P60504 for 12V and P60430 for 6V, as per the link below

I am pretty sure I installed this pump, which has worked well so far for me.

Hope this helps
