Here's a correct oil pressure sending unit for all muscle-era ('1960s-'70s) RWD Mopars, smallblock (273-318-340-360), big block (361-383-400-413-426W-440-4-440-6), and 426 Hemi. This screws into the rear of the block and transmits the oil pressure information as a voltage signal to the stock oil pressure gauge. (NOT for cars with oil idiot lights!) Patented design improves accuracy!
Besides the obvious danger that comes from not being sure what your oil pressure actually is, these units, when old, sometimes cause a mysterious (only at times of high pressure) oil leak at the rear of the engine, which is often misdiagnosed as a rear main seal. Can you say: "hassle"?
This unit is made by the original Chrysler / Mopar vendor, OEM "gold" cad plated finish. Just screw it in and go spank some rice! Life is good.
