I posted a week ago about this. I tried taking the vacuum line off my aeromtive fpr and no fuel came out, but i still believe it is the problem. I started the car up ( hard starts from no fuel pressure) and the pressure pumps right up. turn the car off and my fuel pressure returns to zero in about 10 seconds (timed it) fuel pressure also drops as im driving from 45psi all the way to 21 (where itll bounce around at) within 20 minutes. Should i contact aeromotive for a replacement unit?
