    1994 TBI 454.
    It's not above the oil filter.
    It's not at the rear of the lifter valley.

    The oil pressure guage works...so where might my sending unit be?

    They usually put a little elbow adapter for it, and the sending unit should be under the distributor, where you wont be able to see it. Other than that and the oil filter, I dont know.

    What do you expect it to look like? The pressure sender and switch were combined by '94, and is a simple black plastic cylindrical piece with a 3 wire connector.

    Well, I'm not sure what I expected it to look like exactly, but I did expect a device with a 1/4" NPT fitting screwed into the block somewhere with wire(s) coming out the other end.

    They didn't run them off the front of the block did they? I know on some of the SBC's there is a tapped hole that is plugged, but to my knowledge was never used for anything. Wonder if the later 454's had something similar?

    Not much experience with BBC's, no idea where else a pressure tap would be.
