Just offering a suggestion. I would mount a metal fuel filter at the tank or near the tank. When I see rubber line and clamps near the carb. I get worried, WHY?
After many heating and cooling cycles, Rubber hoses MAY crack and MAY leak.
That could be why Chevrolet used a solid METAL line to the carb. from the fuel pump.
The see through filters ( glass & plastic) and other kinds that use rubber hoses are NOT a good idea around any type of heat.
Bottom line is stay safe. A fuel leak on your engine or near the Carb. at 50--60 MPH. It is NOT,,,,, For the most part a " Happy Outcome ". Think about it?
HEY,,, Its your car, Do what you think is good for you and your car.
On my 70 468 driver and my one owner 70 SS 454/ M-22 I have metal filters at the tank. WHY? I do NOT want to keep taking the Q-Jet apart to change filters, Paper or Stone.
I do not want to get into the problems that you can have by working on the old Q-Jets. I have NOT touched my two Q-Jets in years. Change the filter at the tank and you are good to go! This is just something to think about!
