Here is something you don't see everyday. Some good used Nostalgia/ Lil Bertha fuel pump gear sets with wear plates. Each set includes two gears and two side plates. RBS realizes that over time a racers combination can change and the need to change the gallonage on a Waterman fuel pump happens quite regular so take adavantage of the gear trade in program.
Here is a breakdown on Waterman Little Bertha gear sets. They start at 13 gallon and can up to 32 gallon. Gears with wear plate will measure 1.700" overall width. With each .050" increase in gear width the racer will gain a gallon of fuel. Example below:
.700" 16 gallon
.750" 17 gallon
.800" 18 gallon
.850" 19 gallon
Nostalgia gear sets are good for 10 gallon to 22 gallon fuel pumps and gear sets do not interchange between the different versions of Waterman fuel pumps. Gears with wear plate will measure 1.200" overall width. With each .050" increase in gear width the racer will gain roughly gallon of fuel. Example below:
.600" 13.85 gallon
.650" 15.00 gallon
.700" 16.50 gallon
.750" 17.25 gallon
.800" 18.50 gallon
.850" 19.50 gallon
.900" 20.50 gallon
.950" 21.75 gallon
1.00" 23.00 gallon
1.10" 24.95 gallon
1.20" 26.75 gallon
1.30" 29.00 gallon
1.40" 31.25 gallon
1.50" 33.50 gallon
