Fuel pump broke, emission tube broke and car won’t run, repaired tube with metal sleeve, will it be okay to replace pump and use on car
That would be entirely up to you and the laws in your area.
Catalytic Converter (CAT)
Catalytic converters are used to convert carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NOx) into water vapor (H2O), carbon dioxide (CO2) and nitrogen (N2). The catalysts used to create these conversions are palladium, platinum and rhodium, depending on the type of converter.
During engine operation, all of the exhaust gases flow through the converter where a chemical change takes place. This change causes the temperature inside the converter to be higher than the temperature of the exhaust gases when they leave the engine. Due to this increase in heat, the converter is insulated so that its outside temperature is about the same temperature as the muffler. However, due to its solid mass, the converter remains hot much longer than the muffler. The converter body is made of stainless steel designed to last the life of the vehicle and may be of the monolith or pellet type.
Although all vehicles with a catalytic converter must use unleaded fuel, small amounts of leaded fuel can be used in case of an emergency. To prevent adding leaded fuel, the fuel tank filler nozzle has a built-in restrictor.
The conventional Oxidizing Catalytic (OC) converter uses palladium and platinum, included as a fine coating on the substrate, to reduce harmful exhaust fumes.
The Three-Way Catalytic (TWC) converter contains palladium and platinum as conventional oxidizing agents in addition to rhodium.
The dual bed (TWC+OC) type converter is two converters in one container. The front or upper half is a Three-Way Catalytic (TWC) converter, while the rear or lower half is a conventional Oxidizing Catalytic (OC) converter. The rear or lower half has a provision for air injection.
The Warm-Up (WU) converter is installed in the exhaust system ahead of the main converter and operates on the same principle as the main converter, but reacts more rapidly to incoming gases. It is especially effective in converting gases immediately after start up.
The maniverter is a combination exhaust manifold and catalytic converter and operates on the same principle as the main converter.
The catalytic converter may be installed at or near the exhaust manifold or in the exhaust system along the vehicle underbody or may be a maniverter which is a combination exhaust manifold and catalytic converter. The converter body should be inspected for distortion and other types of damage. Excessive heat can bulge or distort the converter. Since excessive heat buildup is not the fault of the converter, the fuel or ignition system should be inspected whenever a converter is damaged by overheating. Also inspect for missing or improperly installed converter heat shields.
