Boot and Transfer Plate Installation
NOTE: Installation of the boot is the same whether the tank has the standard collar or the Sure-Flo
Feed Flow Control.
Slide the boot as far as possible into the tank collar or the Sure-Flo Feed Flow Control opening.
(See Figure 1.) Align the boot with the Flex-Flo System that will be installed. Using the holes in the
collars for guides, drill eight (8) 11/32" holes into the boot rim. (See Figure 2.)
Mount the boot to the collar with the hardware provided. Bolt the Transfer Plate and Unloader Braces to
the boot as shown. See Figure 3 for proper usage and assembly direction of hardware for mounting the
boot and the transfer plate. All connections should be tightened until they are “snug”.
