I have heard bad things about the bearing on walbros. I have a cosmo pump pushing fuel to my 720/1680 injectors. It gets me to 16psi boost (which requires about 60 psi fuel pressure) on my t04S with no pressure drop problems. I think this is about 375rwhp range. I have also run the supra TT pump and it delivered well also until it died .

Aeromotive A1000 with a constant 12V relay as well, but i'm looking into getting the Aeromotive Fuel Pump Controller to control the pump.

Aeromotive Eliminator

It's shelf-warming right now, as much of the car as I restore. I'm considering a speed controller.

My new Aeromotive Eliminator takes My T04R up tp 25 PSI and I have below 90 % duty on the PFC. The Aeromtoive A 1000 is not near the pump the Eliminator is hence it is more expensive and it is also more quite.

Well, for the time being (until I need more fuel) I’m running a “y” in the tank and using the stock feed line. To trip the relay you need to look here: http://www.nopistons.com/forums/inde...3&hl=12v&st=25

The pictures are on page two.
