Has anyone had luck with a spectra fuel sending unit .the sending unit i have in the car goes to full then drops like a rock to empty after a few miles on my 66 Dart .Thanks
Thanks ,you just saved me money.im in Canada so i dont know to send one to be repairedYes,
They suck. They read completely wrong. I have not been able to find a a/m sending unit to work with the early a's. I Have the original one sent out for repair instead.

Any ideal what tweeking it requires,also is it the same has a 66 DartThis is one of the most needed reproduction part. Nothing out there is accurate out of the box.
This one is the closest you can get, the same design as original but still requires some tweaking.

Do you still have the OEM unit? If so, get it rebuilt by Instrument Specialties, Inc., N. Kingstown, RI 02852.Has anyone had luck with a spectra fuel sending unit .the sending unit i have in the car goes to full then drops like a rock to empty after a few miles on my 66 Dart .Thanks
Not sure where you are going here, but tvat sender is easily repaired. The how to here on fabo details the procedure.Moral of the story is, do not just blame the newer aftermarket design. There may be more contributing factors involved
Mine goes from full to empty after a few milesNot sure where you are going here, but tvat sender is easily repaired. The how to here on fabo details the procedure.
As for aftermarket senders...
If the sender is not tuned to the guage AND the tank it will never be accurite.
If your aftermarket sender is tuned to your aftermarket guage it should read fairly accuritely. Only the shape of the tank is the variable and after the first 5 gallons or so the tank is fairly liner.

Hole in float, causing it to sink and registers empty?
You can disagree all you want but the science is valid. The aftermarket senders with NON aftermarket guages are not compatable.We have all read the Values of resistance oh so many times
I dont have everything you have ,what would be an easy close way to adjust .it dosent need to be perfectI have the A100 sender in one of my cars and its damn close. Not perfect but good enough. I had a tank on the bench and spent some time adjusting the float lever and the full stops until it read right. I hooked up an oem fuel gauge to it running off a 5v power supply to verify operation.
I also run a solid state VR for fuel gauge. No more bouncy needle.
What is it i should see .You can do it in the vehicle. Mount the sending unit, remove the filler neck so you can see inside.
ThanksMake sure the float is going all the way to the bottom of the tank and all the way to the top. Move the float by hand and verify the readings on the gauge at multiple levels.
My aftermarket sender stopped working after some years. Its issue was a hole in the float. When float fills and sinks gauge stays at empty , not come and go. Entire new sender from Rockauto didn't cost much more than a new float and seal would have cost.This is plausible, However if it does the same thing every start-up cycle then no. Wiring/Sensor/Gauge are all suspect!
