BRONZE INLET FILTER

Installing a bronze fuel filter in a Rochester B carburetor is a good measure to ensure clean fuel flow and prevent any debris from entering the carburetor. Here's a general step-by-step guide to help you install a bronze fuel filter:

1. Safety First:
   • Ensure the vehicle is in a well-ventilated area.
   • Disconnect the vehicle's battery to prevent any accidental sparks.
   • Make sure the engine is cool to touch to prevent burns.
2. Locate the Fuel Inlet:
   • On the Rochester B carburetor, the fuel inlet is typically where the fuel line connects to the carburetor.
3. Remove the Fuel Line:
   • Place a container or rag beneath the carburetor to catch any fuel drips.
   • Using a wrench, carefully disconnect the fuel line from the carburetor.
4. Remove the Old Filter (if present):
   • Some Rochester B carburetors may already have an inline filter or a screen filter in place. If so, remove it. This may require unscrewing a fitting or nut where the fuel line attaches.
5. Install the Bronze Fuel Filter:
   • Insert the bronze fuel filter into the inlet fitting of the carburetor, ensuring it fits snugly. There is a spring that resides in front of the filter in order to hold it against the inlet, otherwise fuel will go around the filter.
   • Some bronze filters might have a specific direction of flow. The open end goes toward the fuel inlet. Make sure you install it in the correct orientation.
6. Reconnect the Fuel Line:
   • Screw the fuel line fitting back onto the carburetor, making sure not to cross-thread or overtighten. Do not use any sealer, or teflon as it will get into the needle & seat.
   • Ensure that the bronze filter stays in place as you do this.
7. Check for Leaks:
   • Reconnect the vehicle's battery.
   • Turn on the ignition and allow the fuel pump to pressurize the line (if it's an electric fuel pump).
   • Start the vehicle and let it idle.
   • While the vehicle is running, carefully inspect the area around the fuel inlet on the carburetor for any signs of fuel leaks.
8. Complete the Installation:
   • If there are no leaks, the installation is complete.
   • If you notice any leaks, shut off the vehicle immediately and double-check your connections. Ensure that the filter is seated properly and that the fuel line fitting is tightened securely.

Regularly inspect the fuel filter and replace it as necessary. Over time, even bronze filters can become clogged with debris, affecting fuel flow and performance.

FUEL INLET FITTING

This is what we call an inverted flare fitting. The flare on the fuel line end fits up against the flare inside the big fitting. Not teflon tape should be use and the fuel line doesn't use a gasket. The big fitting does use a gasket behind it.

It is common for an old overused carburetor to leak gas here. Not much you can do except replace the inlet line fitting and the big nut.
