Does the fuel pump controller vary the voltage through resistors? Or is the pump somehow pulsewidth modulated?

 

I do not think it would work with the factory controller. To be honest I am not sure. But it is easy enough to hook it up to MAF, TPS or a hobbs switch.

 

Here is a link to them. http://www.fuelab.com/index.php?option=com_virtuemart&page=shop.browse&category_id=1&Itemid=3

 

From instructions:

Pulse-Width Modulation or other means of reducing input power voltage may result in erratic or non-operational condition

 

Something else cool about these:

Fuel Pump may be mounted inside a fuel tank or cell

 

We actually are installing one of these in a Legacy GT as an in tank pump in the next week or so.

Actually the Fuel Lab pumps have a built in controller so that you don't have to run it 100% all the time. It does 66% at low mode and 100% at high mode that is switchable through any 0-5v source.
