I have had my BJ-8 in storage for a few months and upon starting the following occured: When engaging the ignition switch to "on" the fuel pump clicked rapidly until the fuel bowls filled and then stopped. Just like normal. A few seconds later it clicked again. I pulled the choke and engaged the starter and the engine fired very quickly. While idling the fuel pump clicked pretty rapidly - every few seconds. The engine idled well with no issues. I took the car for a short drive at about 35 mph max (neighborhood streets) and the fuel pump clicked about every two seconds. I don't recall it clicking that rapidly before but I hadn't driven the car recently. I became concerned so returned to garage the car to figure things out.
I did not smell fuel or observe any fuel dripping from the overflow tubes. And, the engine ran great so I don't think excess fuel is going from the carbs to the engine.
I have a couple of questions: First, this is an OLD fuel pump - I replaced the original pump in 1973 so it is 46 years old. Is there a diaphragm in this pump that could have cracked or failed in some way due to age and the new fuels?
Second: Is it likely that the original fuel line from the tank to the pump has a minor air leakage?
Third: Is it likely the issue is just the connections to the pump have loosened?
Fourth: Are there any other possibilities?
Thanks in advance for your assistance!
