Excellent feedback Guy's, I was indeed thinking on keeping the mechanical pump in line and wire in this new pump as an auxiliary pump to a "rocker switch" use only for cold starting and run her on the mechanical pump at WOT etc. With fuel flowing freely through the free flow pump and regulator.
My proactive concerns is restriction at WOT with the vacuum pull having to suck through a Pump/Primer Bulb/regulator/pump/filter/ etc.
With the mechanical pump connected I thinking it can boost the fuel pressure up out of tolerance for the Carbs....
Spare sorry about the fonts I did a few Cut & Paste from Ebay etc :) The cold starting at the ramp drives me crazy. Once the primer is primed and she started it starts at the bump of the key there after. Its clearly lack of fuel since I observe the primer goes very very soft before the hard starts.
