The slave cylinder is a pressure controlled, single acting, spring return unit.  It has a lever with rod endis suitable for connecting with a high idle cylinder or with a link to the lever of the fuel pump.

The lever is adjustable for precise adjustment of the stroke and is reversable for the pulling instead of pushing function.  The lever attachment is turnable in 90deg intervals relative to the munting bracket and the bracket can be adjusted along the length of the cylinder.

Pressurising the cylinder against the internal springs results in a lever movement proportional to the pressure, activating the fual pump.  When the pressure is exhaused, the springs are retracting the lever back to the initial position.
