I just replaced the 3 piece fuel pump to carburetor line set and replaced both the inline filter canister and carburetor inlet filter. All went well. No leaks, engine starts and runs very well, but I notice the 3/8" rubber inlet hose that connects into the fuel pump from the hard line from the tank is pulsating. Its not just a little; its easy to see but again no leaks and engine runs fine. Is this normal? I've never noticed it before. Sorry to be so wordy. Thanks.
Yes its normal, mines been doing it since I've had the car, 33 years now, original rubber line too..
OK, good to go then. Thanks Mark.
