RF is simple cylindrical plunger type with conical top, controlled by
the spring. To make sure its working correctly, unscrew the oil pressure
sender, take the spring and plunger out and inspect and clean the
plunger, and the alu sealing seat. Then insert the plunger with a screw
that fits snugly inside of it, and extends enough outside that one can
hold it, and slightly tap on it with a small hammer several times, to
make sure it made a good seat. Take the plunger out again and inspect
and clean again. Lubricate and assemble. You can preload the spring with
a steal washer, if the opening pressure wants to be slightly increased.
If desired result isn't there, your oil pressure problem is elsewhere.
