which the system may be exposed, in accordance with Sec. 56.07-10(b) of 
this subchapter.

fixed storage tank having sufficient capacity to recharge at least one 
power actuating system including the reservoir. The storage tank must be 
permanently connected by piping so that the hydraulic system can be 
readily recharged from within the steering-gear compartment and must be 
fitted with a device to indicate liquid level that complies with Sec.
