Re: not starting 87 tbi truck? please help!!!

Yea Both tanks have an In-Tank fuel pump . So when you hit the switch you send 12v to the other side tanks's fuel pump...

This is why 87 Dual tank stuff is one year only, like the wiring, the switch, the tank, sending unit, fuel pump. It's all 87 only because of TBI
