go to a dealership and ask for a manual and copy it
On the 88 Bronco it should be just above the engine oil filter.
"http://wiki.answers.com/Q/Location_of_oil_pressure_sending_unit_1990_bronco_351"
Best bet would be E-Bay
The oil pressure sending unit is on the front drivers side of the engine towards the bottom it has a hex shaped stud screwed in the engine with the sending unit screwed into the end of the stud. It has the electrical line on the tip.
For a 351m engine the oil sending unit is located on the top of the engine between the carburetor and the firewall.
Top center of engine at rear of block behind intake manifold.
If you are talking about the 86 fullsize bronco on the driver side of the intake there are two sensors bolted onto the intake the one in the back is the knock sensor good luck finding one they are discontinued if you do let me know where you found it I am looking for one
if its a full size fuel injected bronco 87 or later the pressure should be between 35 and 42 psi
The oil pressure switch is located between the carburetor and the firewall on top of the engine. You will need a 9/16 open end SHORTY wrench to remove it.
thats what i am trying to find out? thx
Size. The Bronco is a full sized vehicle. The Bronco II is the miniature compacted version. The full size broncos came with larger v8 engines and the Bronco II was designed during the first gas panic as a Fuel saver. While they only get 22mpg, on the highway it was almost double what the full size broncos got in mileage, except for the 4.9 I6, which could get 20mpg in the fullsize. In addition, the bronco ii was based off of the ford ranger, while the ford bronco was based off of the ford f150.
