    I need to know where the oil pressure sensor is on my 91 Suburban. I'm fairly sure I've located it, but want to verify. Anyone know the GM p/n or local parts house p/n?

    Thanks in advance...!

    The oil pressure sensor on my 400 smallblock is just behind the distributor in the intake manifold, towards the driver's side. Sort of looks like a bell with a wire coming off the top.

    Don't have a P/N, but per the service manual for the 90 350.. V8 & V6.. The sensor is located at the left front side of the distributor. Use GM Tool J35749. See Figure 10.. (which i can't quite trace and put in here.. ), but it looks as if it's on a 'stand-off', just below and to the side of the distributor. The pic of the tool doesn't look anything special, other than perhaps the size. (ain't those 1 1/8th or some such thing?).
    Hope that helps a bit.

    Thanks Jim and Jed.../forums/images/icons/smile.gif

    That's where I thought it was...

    My service manual met an untimely demise, unfortunately, due to an improperly placed cigarette. Someday my buddy will actually pay me back the money so I can get a new one!

    In the meantime, I'll have to revisit Helm for a new one soon...

    No prob Alan!
    Still happy to share anything in my '90' set that may be of help. (think we had part of this discussion! ) I've had to refer to these several times, and haven't found anything that didn't fit.. (yet)...
    Sorry to hear your 'correct year' set turned to ash!

    Would it be in the same location on a 79 K5 400SB?
