Re: {Chrysler 300} Oil pressure senders for 300F?

[John Grady <jkg@xxxxxxxxxxxxxxxxx>]

yes if reading high especially pegged it us either the  sender ( but somewhat unlikely to fail shorted ) or the wire to the sender is shorted to ground . Anywhere along its length , including at or in gauge . Check physically and then disconnect both ends and read with ohmmeter to ground , should be infinite ( no reading) 

I would try to get one out of a same app ( 60-62) junk car ( Murray Park , big M ) as most replacements are a crude attempt at universal , and may not read right .

This is especially true of temp sender . I never did find a replacement that worked right on two different occasions .I adjusted with external resistor. Maybe you get lucky . 

And  oil gas and temp senders are different for magnetic  gauges used pre 60 vs thermal gauges 60 up .

hope this helps .

 Any problems with thermal regulator impacts all the gauges . They are surprisingly reliable in my experience . If you see little jumps on needle as you turn on ignition it is working perfectly , easiest to see on gas one with full tank

Hey Nick

Yes, gas gauge works fine.

Is the gas gauge working properly?

Folks

The needle for the oil pressure gauge in our F stays pegged at the far right when running and guessing it’s the sending unit. I see that Napa has an Echlin unit for about $54 and a Napa brand for about  $21, which is a huge variance.

They look the same on the web page but wondering if the group has any thoughts on significant differences?

Thanks in Advance,

Keith
PS: I did buy a new voltage regulator a while back because someone said that could also be the problem but I haven’t installed it as was thinking the sending unit might be more plausible as a the culprit.
