Kavlico sensors

[uk_figs]

Just replaced my original VDO fuel and oil pressure sensors with the newer Kavlico sensors and noticed that the Kavlico sensors do not have the restrictor input that the VDO sensors have. Is this because the Kavlico sensors are solid state and not diaphragm based so loss of oil etc. is not likely?

Also anyone have the part number or replacement for the 3 contactor hobbs/low oil pressure switch as that appears to be leaking.
Thanks

I think it is possible, and also possible that your hose to the sensor could leak or burst, which is why I believe the restrictor fitting is normally on the engine side of things, then the hose, then the sensor, such that everything downstream is protected.

Kavlico P/N: 103757-000 I paid $129. This is the 0-150 psi sensor that replaces the unit mentioned in a Dynon S.B..

Long time since I finished the RV, anyone know if the engine side restrictor fittings came in the finish kit?

Not sure myself, but several references say 2 come in the FWF kit. You can also just buy them directly, they are modified AN823-4 fittings, which Van's labels as VA-128.

They show up in the OP-27 - Oil System diagram.
