Howdy All!
My current fuel system is an aeromotive a1000 pump, with an FPSC (Fuel pump speed controller) to 'control' it. Fed to a A2000 series fuel pressure regulator.
This then feeds a AED Eliminator carb atop of a 306.
The issue I have is that when the car runs with the FPSC on -- at cold idle I set the fuel pressure to 6.5 psi, All is well till the car warms up. Where it then drops down to 0 on the fuel pressure gauge -- the pressure regulator line to the carb has the gauge in line with the line to the carb. Everything is cool to the touch, nothing is 'hot'. It is a liquid filled gauge if that matters. The Fuel bowls stay full at the level they were set to and the car runs and drives OK.
The car doesn't seem to 'struggle' or anything to that point, and I haven't bypassed the FPSC yet. Is my fuel pressure situation coming from the FPSC? Or is it something other than that?
Id like to know what I'm getting into before I start taking things all apart.
Could the FPSC cause these issues? Does the boost reference port on the regulator need to remain plugged (as it is) or should i hook it up to a vacuum line? Let me know.
