Thread: Oil Pressure safety switch & sender

Tweet

96 thru 2000 vortec 350 engines (Chevy truck) has a oil pressure sender/switch (two circuits) that can be used. As I remember, the sender does not have enough current capacity to run the fuel pump draw thru but it can be used as the control for a relay.
It has a pipe thread, just as all SBC engines.

I was thinkin the same thing,and every vehicle made since 1985 ? or every thing with an in tank fuel pump runs a similar switch. But finding one that has the right resistance to operate his oil gauge is another thing. On a carbed vehicle I'd be more inclined to use a Ford inertia switch.
