EGR - Exhaust Gas Recirculation: Exhaust gases containing unburned fuel are recirculated back into the engine to be re-burned. EFE - Early Fuel Evaporation: Right side exhaust manifold gases (heat riser side) are recirculated to reduce emissions and shorten engine warm-up time. TVS - Thermal Vacuum Switch: A temperature sensitive switch that controls vacuum supply to other engine components by opening and closing at specific temperatures. A.I.R. - Air Injector Reactor (Smog Pump): A belt driven pump that injects cool outside air to the exhaust valves to promote combustion of unburned fuel. TCS - Transmission Controlled Spark System: Introduced in 1970, this system controls exhaust emissions by eliminating vacuum advances in the lower forward gears. Emission Hose Sets Vacuum hose kits include all correct color hoses and connectors to properly connect the following components as required: Distributor vacuum advance control, carburetor choke vacuum control, smog pump diverter valve, EGR valve and fitting, EFE valve and fitting, spark controls, carburetor idle control, air cleaner vacuum diaphragm, and clean air and choke tubes. 303500 68-69 Vacuum Hose Kit, 3x2......................................12.95 303531 68-69 Vacuum Hose Kit, 1x4........................................8.00 303543 70 Vacuum Hose Kit, 300/350 HP........................10.00 303537 70 Vacuum Hose Kit, 390 HP..................................9.95 303553 70 Vacuum Hose Kit, LT-1....................................13.00 303547 71 Vacuum Hose Kit, LT-1....................................14.00 303550 71 Vacuum Hose Kit, 270 HP................................10.00 303534 71 Vacuum Hose Kit, 365 HP..................................8.00 303557 71 Vacuum Hose Kit, 425 HP................................13.00 303540 72 Vacuum Hose Kit, 200 HP..................................8.00 303560 72 Vacuum Hose Kit, LT-1....................................13.00 303542 72 Vacuum Hose Kit, 270 HP................................13.00 303536 73 Vacuum Hose Kit, 350 w/Standard Trans........13.00 303551 73 Vacuum Hose Kit, 350 w/Auto Trans...............15.00 303546 73 Vacuum Hose Kit, 454 w/Standard Trans........14.00 303539 73 Vacuum Hose Kit, 454 w/Auto Trans...............17.00 303556 74 Vacuum Hose Kit, L48 w/Standard Trans........13.00 303549 74 Vacuum Hose Kit, L48 w/Auto Trans...............14.00 303532 74 Vacuum Hose Kit, L82 w/Standard Trans........13.50 303554 74 Vacuum Hose Kit, L82 w/Auto Trans...............13.00 303544 74 Vacuum Hose Kit, 454 w/Standard Trans........14.00 303558 74 Vacuum Hose Kit, 454 w/Auto Trans...............16.00 303541 75 Vacuum Hose Kit.............................................22.00 303555 76 Vacuum Hose Kit, L48 Exc.
