Yes it does. The main line goes from the pump and connects to the fuel splitter solenoid.
I will need to go over the troubleshooting you suggested as well as the vent cap and cannister.
I have a 77 GMC C10 High Sierra it is a Dual Gas Tank. I have changed the Mechanical Fuel Pump to get it to run (it does kinda) but shuts off within a couple seconds unless being directly fed through a jerry can. So I went and bought the fuel tank splitter hoping to be able to solve the problem...
Thanks a lot. Sorry for responding back so late busy trying to get the truck to run. Actually, I'm from Delhi, CA (I was in a hurry to create my account forgot to put the state my bad) It is, however, a small little town still.
Can anyone help me identify what this cable is leading to. It is located next to the master cylinder.
It is on a 1977 GMC 350 V8 c10 Dual Tank (automatic).
The last picture is a sensor? on top it says Hold/Engage what is this?
