I did reroute from the mechanical pump under the alternator over to the inner fender and straight to the carb. I had planned on picking up some insulation tonight, but I don't have high expextations. Having zero improvement so far, I'm guessing it's boiling in the bowls.
Couple more questions though.
I have never purchased an electric pump before and I see a broad range of gph choices. What range should I be in for a 600cfm carb (EB 1406)? Or more importantly what is the criteria for choosing the proper gph? Is there any concern of fuel sneaking through the carb circuit before the float closes the needle due to overpressurization?
