When to add sea foam to diesel fuel?

For cleaning, use 2 or more ounces per gallon – the more you add to fuel, the better it cleans! Add when the tank is low to maximize cleaning concentration.

What kind of fuel injection does a GM 454 have?

Does his engine have 2 4 barrel carburater or a throttle body Fuel Injection. If a 4 barrel it might be the accelerator pump. I’mpretty sure Tim’s is a throttle body injection like mine. These look like a carb but are far from it.
