Perkins 4-108 Oil Pressure Sender Specs

[Dynamo1181]

Can someone give me the specs for the 4108 oil sender? I replaced the bad unit with an 80 psi Teleflex model and now get a full scale reading. I suspect I can put a 40 resistor in line and get the reading to the 50psi range but would like to know what the perkins part specs might be. I did purchse a generic sender from Napa but the unit didnt last long under diesel vibration. Any help appreciated to include a supplier of the OEM unit.
Thx

I will try and get the model number for you this weekend.

What make of gauge do you have?

Remote mount a standard 80lb oil pressure gauge, and use a flexable high pressure hose to the oil passage used for the gauge sender. easy and cheaper then a stock gauge ! Just a thought.

I am running the standard Perkins panel which is Teliflex. The Teleflex sender that I put in is spec'ed at 33-240 Ohms. I know via manual gauge that the pressure should be at 40+-. The new set up reads full scale 80psi at start-up. I am guess that the Perkins sender should be somewhere in the park od 70-280 ohms. If I could get someone to measure the resistence between the stud and ground at off to confirm what, I can add the resistence. But I would like to know the std resistence range of the perkins part and if that stock sender is a 120psi for my 80 psi gauge.

PS: Thx CB...How is the shaft seal holding on the injection pump?
