Abstract
A conversion mechanism for selective conversion of a conventional mechanical fuel pump computer to selectively extend the unit volume price range of the computer while maintaining the rotational speed of the right hand cost and volume counter wheels of the computer within acceptable limits and mathematical correspondence of the volume counter readout with the cost counter readout and the established unit volume price. The conversion mechanism comprises cost and volume drive ratio selector mechanisms and one or more sets of single transfer, double transfer and quadruple transfer right hand cost counter wheels and a decimal point selector mechanism for shifting the decimal point of the unit volume price setting and/or cost counter readout.
