It has been discovered that improved polystyrene products may be obtained by polymerizing styrene in the presence of at least one multifunctional initiator, at least one chain transfer agent, and at least one cross-linking agent. The endoskeleton may include columns to support fuel system components, first and second beams staggered with respect to one another and having tank contact portions attachable to the tank body, and walls extending between adjacent first and second beams to baffle fuel and to yieldably restrain movement of the body. The header contacts have mating segments for termination to corresponding receptacle contacts of a mezzanine receptacle connector and terminating segments for termination to a circuit board. The indicating means includes a processor and receiver and wherein the transmitter transmits the signals generated by the determining means and the receiver receives the signal and provides the signal to the processor for determining the position of the bolt and generating a signal indicative of the determination. With an operating portion and a displaying portion having an input field with a plurality of lines, character information such as titles of individual programs in a plurality of character formats can be input at a time.
