[J-440]

Aight Greg, here we go:

The car idles great except for the fuel pressure fluctuating. Then when I start turning on accessories and then the electric fan kicks on, the voltage drops to 10.2. I mash the throttle and the car falls on its face and sometimes dies.
The entire fuel system is new from front to back. I'm using -10 feed line and -8 return line (overkill for now but planning on power adder in future). The pump is mounted about 6" higher than the tank above the rear axle, I'm using 2 filters, before and after the pump, the tank and pickup are brand new from Rick's.
The car only has 350 miles on it. I did have to replace an Optima yellow top because it couldn't hold a charge. Then soon after the alternator took a crap and so I sent it back to have it rebuilt. Man I'm pretty sure this is an electrical issue. Gonna keep trying again today. Keep that advice coming.
