Oil Pressure Sending Unit...Parts Guys Please Look - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**LEEVON** · 11-30-2007, 11:30 PM

I want to replace the oil pressure sending unit on my '87 305 TBI because it's leaking like a sieve, but the parts counter guy could not find it in the system. We looked at every fuel related part for my truck with no luck. Does anybody have the part # or are there any parts guys out there that can steer me in the right direction?

Thanks.

You need to look for an Oil Pressure Switch/Sender. I looked it up but cant say forsure what one yours would need. Goto Partsamerica.com then use your vechical info and lookup Oil Pressure Switch/Sender you should see everything listed. If not let me kown. I looked up an 86 and I seen what ones look normal to me. Looked at the 87 and they are different.

those are the part numbers as described in the year one catalogue if you want you can contact them online or via phone.. it should be readilly available at Napa on line or any other decent auto parts store

87-UP combinesthe oil pressure sender and switch in one unit. If teh engine doesn't see enough oil pressure (I think it is ~5psi) it will not turn on the fuel pump. I don't have a part number, but it is only one part. I am pretty sure it is called a switch, though.

the info i posted describes the part as an oil sender switch and it is the only part
