Did the 454's come with electric or manual fuel pumps? The IT manual I have shows a manual pump but I've got an electric. Anyhow... The tractor has been sitting for a year or so without running. I've got the tractor to where it will crank and cough but it is flooding the carb. I read in the archives the float/seat/and needle valve are probably bad. What keeps the electric pump from over pressurizing the carb and blowing past? Should their be a regulator or return line? Thanks!

If you are talking about a small, pulse-type electric fuel pump, they are self-limiting to a specific pressue, usually between 2 and 8 psi, depending on model number.

If you are talking about a vane or gerotor type pump, as is used in racing or fuel injection applications, these normally need a separate regulator.

I'd say it the pulse type fuel pump. It's worn and the numbers are no longer visible. When running it sounds like it's pulsing. So it's probably carb rebuild time? Thanks!
