Sierra Oil Pressure Sender OP24891, Replaces 82514/90511, 80 PSI, White, Universal Fit
Sierra Oil Pressure Sender OP24891, Replaces 82514/90511, 80 PSI, White, Universal Fit
The Sierra OP24891 Oil Pressure Sender is a Sender Code C oil pressure sending unit built for a 80 PSI DS range, designed to send an accurate signal to a compatible oil pressure gauge as engine oil pressure changes. It uses a 1/8-27 thread size for mounting into the oil pressure port and a 10-32 stud terminal type for the gauge wire connection, matching the common terminal style used on many marine and automotive oil pressure gauge circuits. The sender's resistance output moves through a defined range as pressure rises: 120 Ohms at 0 PSI, 98 Ohms at 10 PSI, 77 Ohms at 20 PSI, 32 Ohms at 60 PSI, 25 Ohms at 70 PSI, and 17 Ohms at 80 PSI, giving a gauge calibrated to this range a consistent, repeatable reading across the full scale.
The housing is finished in white with a machined exterior, and the unit measures 3.63 x 2.75 x 2.5 inches and weighs 0.37 pounds. It ships as a single sender per package and is built to meet or exceed the performance of the original equipment part it replaces. Fit is universal, so it is not tied to a single engine make or model, making it a straightforward replacement wherever a Sender Code C, 80 PSI DS, 1/8-27 thread, 10-32 stud oil pressure sender is required.
