I'm out for the moment because I'm doing work on the fuel system.
The pump has all -10 in and out lines. The filter is the proprietary Aeromotive filter with -10 in and outlet. The bypass is also the proprietary Aermotive with -10 inlets and a -6 return. Pump is lower than the surge tank so it should feed the pump all by itself.
Not sure what's going on.
Opinions are like assholes, everyone has got one, but everyone thinks everyone else's stinks.
