Re: 1973-1991 Dual fuel tank systems theory of operation
hatzie, thank you for the reply, so do the contacts start/stop power to the motor and how can "a guy" check to verify the motor switched completely from one side to the other (not partially switched or in between the ports)?
the system in question is a LS swapped '86 c10 with '87 tanks, '87 sending units & EP381 F.P.s. the 12v signal is coming from the signal at the stock '13 ECM and harness.by chance does the motor require a timed amount of power to move completely? my F.P is low (50-55psi) and trying to verify the valve is not causing the lack of fuel.... ??
again appreciate your time and knowledge.. you are always very helpful on the board.
