A resin intake manifold includes a chamber section having an intake port which leads to a throttle body 91, and a plurality of pipe sections 7 which connect interior of the chamber section to cylinders of a multi-cylinder internal combustion engine. N predrivers receive an output enable signal and a corresponding one of the N delayed data bit outputs and generate a predriver output signal based on the output enable and the corresponding one of the N delayed data bit outputs. The access hub is movable in the port assembly, is engaged therewith through a resilient ring coupling and forms a seal with the resilient barrier, reducing the amount of volume to be primed. A user grips the middle portion of the elongated member with his or her hand and places his or her forearm on the forearm support member. A portion of a first LC resonator inductor and the first LC trap capacitor define an input-side LC trap circuit, and a portion of a second LC resonator inductor and the second LC trap capacitor define an output-side LC trap circuit.
