Fuel pump controler with XFI or not.

[Motown 454]

I'm running a Fast XFI and my fuel pump is a Weldon 1100 A . My question is do I need a fuel pump controller or will the XFI control the pump? Does the XFI just turn it on , or does it control the speed of the pump? I've read that the weldon or Aeromotive pump controllers slow the pump down when you don't need full flow which keeps the fuel cooler and the pump quieter.
Anyone use one of these pump controllers?
Thank you.

The XFI only enables the pump. It doesn't have pump speed control. You'll need a controller it you want it to run at less than full speed.

I'm using Aeromotive's latest pump controller, and it works as advertised.

I have the Aeromotive controller. It halves the flow rate until a designated RPM is reached (adjustable from 2,000 to 3,000). I have a Walbro 255 in tank pump.

The Weldon 14000 pump controller will allow you to slow the pump's speed down while maintaining system pressure or even allowing it to be reduced to lower levels -- however it has not been a requirement. Granted the 1100-A does move a ton of fuel at lower pressures (upwards of 150 gph @ 45 psi), but it has still been used successfully in many street applications without a pump controller.

In testing, it is not been the pump that creates the heat, its the system and if you have a restrictive system, the heat within will increase more quickly than a free flowing system. That pump has been on for days and only increased the fluid temperature 9 deg, it also remained very quiet throughout its operation.

If you are indeed doing more street / traffic cruising then highway or track driving and you've got a small tank or cell -- the 14000 might be a good idea.
