Fuel flowing back after couple of days (super bee 1970)

Sounds like a characteristic. Mine has an electric pump and requires 3 to the floor after setting for a while. You mean 6 attempts or 6 spins on one attempt? Turning the ignition on for a few seconds to let the electric pump run prior to spinning the starter does not seem to make a difference.

a good 5 or 6 attempts - each let's say 5 seconds.

I removed the electric pump - it's now a new mechanical pump on the engine.

I've just been reading all the other comments - the fuel line should be fine as it's relatively new. I'll get it double checked and if nothing install a new electric pump.

The OP is listed as being in Belgium. I would be curious to know if they have ethanol in their gasoline over there.

Thanks from me too, guys.

Probably have to use the same, thanks to the new gas. (Kinda wish the 60s lasted a bit longer.)
