6.1 fuel system help

I modified a stock 71 B-body tank to accept an '08 Viper fuel pump module. 3/8" line from the front of the tank to the firewall with plastic OEM style fuel line connecting the fuel line to the pump and fuel rail with quick-connect fittings. The B-body tank is the perfect depth and the factory fuel pump module has it's own built-in sump. Vipers run the same fuel pressure as the 6.1L and volume should not be an issue. The 'Cuda tank may be very close regarding depth.
