Where can I get the correct sender for a 68 coupe with a 289?
All the local stores sell me what they say is the right one but none of them work. This car has the 6 volt regulated gauges and I need one with between 10 ohms hot and 70 OHMS cold.
I have 5.5 volts right at the connector plug.
Everything locally is between 150 and 240 ohms and does not work

 

Have you called or looked at NPD?

 

Same junk.

You might be able to have one recalibrated:

Have you tried Ford? My local dealership still has many parts for cars of that age.

 

I got a sending unit for my 65 from CJ and it works correctly with my factory gauges with the instrument cluster voltage regulator that is 5-6 volts. It even fits my Edelbrock intake.

When you say its not working, do you mean it doesn't work at all or the gauge reads high?

Your problem may the the ICVR. I went through a few new ones from different places and none of them worked right on my car. My original one still works. We ended up making our own electronic one. I think NPD and Paddock sell electronic ones.

 

You know, you would think that such a simple part would be easy to find. I still have yet to find a retailer/manufacturer sell me the right one, even though they always say its "the right one". I have settled on one that gives me a higher reading than it should, but technically it does work so bleh.....

 

The repair parts available might fit, and even look right, but it's a real crap shoot whether they give the right reading. I just ran-in a new built 390GT, and although the intake at the sender was a perfect 195°-200°, the gauge was 3/4 of the way to "hot".

All of the current fuel senders are crap. Glazier Nolan is working on getting a proper sender made.

Use the link I posted above, they should be able to recalibrate one to perfection.

 

All the new temp sensors are crap. I have yet to find one that read accurately. I finally was able to locate a NOS Autolite one, and solved my problems.

Here is one listed on Ebay right now.

wow 75 bucks plus shipping for a 10.00 part, that is a bit way too mucking futch

 

When I said it is not working what I mean is that I have 5.5 volts at the sender plug connector and if I ground the wire the gauge goes to full hot, so I know the gauge is working and the wire is ok, the senders I find all have too much resitance.

I think Monday I will try the ford dealer again, I tried them for the instrument voltage regulator and was told that has not been available for the last ten years
