Just to add a little more experience. I installed a FiTech unit on mine. I used their pump and filter kit and took the fuel supply from a fitting in the drain plug. The FiTech has run great for me. Fitech said that their control, varies the fuel pump speed based on demand. I don't hear the fuel pump of course my exhaust is loud. The engine starts with a click and idles nice. Never had any indication of knock or vapor lock. Occasionally on shut off when really hot a momentary run on. I'm quite happy with it. The control display is a nice rectangular piece that I mounted under the dash lip where I can watch while I am driving. Really like the second coolant temp readout on the display as opposed to the inaccurate factory gauge. I also get 3 to 4 more mpg.
