Bang Head Re: fuel pump electrical supply, 1984 T-Type

A gauge attached to the fuel rail test port shows about 9 PSI. It takes 1 to 2 seconds to climb from 0 to 9 PSI. This is with the fuel pump powered from a lawnmower battery. The battery voltage measures 12.6V.

With the fuel feed line disconnected half way to the front, the fuel flow into a can looked light (i.e. not 40 PSI).

It's a brand new fuel pump.

Nothing comes out the return line. The fuel tank is hissing after the pump is off, and fuel is trickling down the side of the tank.
