Re: 1973-1991 Dual fuel tank systems theory of operation
hatzie, I just want to make sure that I am thinking correctly. on the EP381 pump (and sender unit) the purple wire(at gas tank) connects to the sending unit wire for the appropraite tank sending unit wire on the switch valve 5 wire harness? and the grey wire connects to the appropriate power wire on the switch valve harness?
thanks!
