If I'm running an Aeromotive A1000 fuel pump do I have to run a controller with it? Because I really don't want to wire anything else into the car. If I do what external pump out there will run without a controller that will feed up to 800 hp. The wiring harness should be fine it's one of the caspers complete engine harnesses that they make with the upgraded fuel wires.

My buddy has a 73 dodge D-100 that we swapped a 6.1 into. He is running a 1000 without controller. Been in there for 4 years and no issues. Not saying it is right but it works.
I don't see a need for the controller. The only advantage is cutting down on pump noise.
Depends on the size of your fuel lines.
If the fuel lines are too small then the pump will draw higher current, run hotter, heat up the gasoline, and hurt itself. The way around that is to run the controller to slow it down a little.. not make heat, and keep cool.
If your running -8's or bigger.. dont see a problem. Same with returns.
The story is common on the Buick with a double pumper setup.. it outflows the returns capability that is why they activate it on a Hobbs switch under high boost.

In a case where the system can't return fuel fast enough, a speed controller can benefit. If the fuel can circulate un restricted, there is no need for a controller. The fuel itself cools the pump. In normal use it never even gets warm.
The stock feed works great as a return. Swap the feed and return at the rubber lines by the frame and flop the filter around. Run a new -8 to the feed. Your done.

Sometimes this is done to save $$. But if your having to run one hose from back to front.. running two hoses is no biggie. Having the two larger hoses eliminates that little bit of doubt that looms in ones head.. "Does it flow enough"
Saves time and $$. I have done it on several cars including my own with pumps that out perform a1000's. The stock feed is plenty for return. No doubt.
I think the perfect controller for a big pump would be the Corvette C6 fan controller. It powers a monster fan, with soft start and soft stop. You could rig that up to control a Weldon pump and still use small lines since it'd be able to vary the pump speed from maybe 15% to around 90% duty cycle.
I haven't done it but think it's entirely possible. Those fan controllers are out there in wrecking yards too.
