Oil Pressure Gauge Switch / Sensor

Mine is leaking oil so i was going to rockauto to order another one, but I see several different part numbers from the same company, all different prices, but all for a 3800. Anybody know which one is "best".

FWIW I do have an L32 but i think the plate is bolts to is part of the filter housing so it would have come off my L67.

For 96 S/C Riv:
STANDARD MOTOR PRODUCTS PS270 {#25535479} OIL PRESSURE LIGHT SWITCH Info
w/ Light ??

$12.92

STANDARD MOTOR PRODUCTS PS246 {Click Info Button for Alternate/OEM Part Numbers} Info One of our most popular parts
w/ Gauge

$21.79

STANDARD MOTOR PRODUCTS PS615 {#19244518} Info
w/ Gauge

$22.79

For 05 GTP (L32)

STANDARD MOTOR PRODUCTS PS279 {Click Info Button for Alternate/OEM Part Numbers} OIL PRESSURE LIGHT SWITCH Info
w/ Light

$11.17

Was able to answer part of my own question, the 05 GTP (L32) type sensor is 2 terminal, the rivs have 4 terminal connectors. SO PS279 will not work with a riv.

Also going to take a guess that since the riv has a dash light and not a dash gauge for oil pressure I should be going with the PS270 sensor.

Yep.

Ended up getting one locally at o'rileys auto. BMD(?) brand. seems to have stopped my oil leak.

Thanks for the reply Albert.
