Some good progress yesterday, all fuel lines fabbed and installed, oil pressure sending unit in and fuel tank installed. Hooked up my battery and gave it a go, but the starter I had was junk. After a new starter she spun up and produced good oil pressure. I then put fuel in the tank and let it prime, checked for leaks none, then I tried to start her, but no go, I checked everything and it appears I'm barely getting fuel to the rail, when I open the schrader valve just a dribble comes out. Time to troubleshoot and then wrap up the radiator/radiator support.
Tapped an old ls1 oil pressure gauge for 1/8 fitting.
Sender Installed.
Fuel tank ring reinstalled, along with a 90 for the fuel vent, both of them welded in then sealed with gm engine sealer.
Return loop.
