Tuesday Tech Question presented by Evans Coolant

Question:

 

I have a mechanical fuel pump that keeps the bowls of my carburetor full and a return line that takes excess fuel back to the tank.  Do I need a fuel shut off valve in the main fuel line to the carburetor?

 

Answer:

 

Yes, in the 2019 NHRA Rulebook General Regulations, section 21, page 5, Pumps/Valves it states “Cars equipped with carburetor(s) or non-electronic fuel (EFI) systems but with mechanical non-OEM fuel pumps must have a quick-action fuel shutoff valve within easy reach of driver and located in the main fuel line between fuel tank and carburetor and/or injectors.”
