i just bought a new oil sending unit for my 305 tbi. the guy said the unit is located on the intake manifold but i can't seem to find it. the haynes manual isn't much help in this area either. any info would be great. thanks. chris.

 

I have an 84 z28 and mine is located on the drivers side right behind the intake manifold. I believe yours should be in the same place.

 

yup

 

my 89 305 TBI Bird was on the left side by the oil filter.

 

mine is a 88 ta. i just looked on the right and still didnt see anything. do you have to access it from under the car or from the top.

 

Well there are to locations for the sending unit. 1 and I believe the most common is on the driver side on top of the motor right behind the intake manifold. 2 is right above the oil filter .

 

my 84 TA has it behind the intake. and my 87 camaro had it above the oil filter. those are the only 2 I've seen too.

 

In general, EFI models (TBI, TPI) will have the oil pressure sending unit/oil pressure switch combo above the oil filter.

Carb'd engines will have the oil pressure sending unit behind the intake manifold.

 

E4ME engines have the switch at the oil filter also, pretty much any 1980 and up carb engine, i dont think ive ever seen anything '80 and up without it, two spade connector,

good luck

 

Only if it had the in-tank electric pump, which was only standard on the '87 model year.

My '86 doesn't have it above the oil filter.

 

My 87 has it behind the distributor and way down there sticking up on a stem with another oil pressure sensor on it. It's way back there. It only took a small wrench and a few minutes to change mine. Mine was a large silver can with a spade terminal. It is for the oil pressure gauge. The small one I think is for the light.
