I want to thank you guys...
GMC: No the valve cover bolts are not staggered,they are inline with each other.
Squeeze...thanks for the picture...This engine doesnt have that "place" for the sender.
I wish I knew more about the engine..the engine was put in by someone I'm not able to talk with.
The intake is a stock looking cast iron part.
So the area for the sending unit SHOULD BE on the INTAKE somewhere? I'll try and post a few pictures today.
THANKS ALOT FOR THE HELP!
