Anyone know where to find a NOS fuel sending unit for a 64 barracuda . china repops are junk , improper ohm readings for mopar . need one real bad.

Looking for a sender? You need to start a parts wanted thread.
 
I bought mine from Rock Auto.
AUTOTECNICA DG0514087 {#4051004, DG0514087} Info
5/16" outlet w/o return. This unit has the proper ohmage of 10 empty and 80 full. $49.79

Please report back on its accuracy, I see is the correct empty/full resistance but everywhere in between empty/full? I don't think anyone manufactures one that works properly.
 
Go to Rock Auto and check the numbers are all there.
I see on Rock Auto the rheostat ranges from 10-80 ohms. i installed an aftermarket similar Chinese sender and yeah it reads empty and full but anywhere else is no mans land. The rheostat (variable resistor) is wound in an even or linear fashion unlike the original which is uneven shaped or non linear.
 
^I'm doubtful^ Nobody I know of has found a source for "modern manufacture" senders that have the proper what is called "taper." The resistor is NOT linear originally, it is a NON linear taper design, and all the repops anybody else has found are all "more linear" meaning, not accurate through the range. It is not just the beginning and ending resistances.
 
rewind your old one. The original had a triangular bobbin the wire was wrapped around to emulate the shape of the tank (fat bottom, narrow top in volume) so the sender had shorter wraps and wider apart where the float is highest because the float swing faster when there is less fuel volume changing level. the shorter wraps reflet smaller changes in the gauge. When the full footprint of the tank is now the fuel level (1/2 full?) after it gets under the spare well. then the change gets smaller and the wires get finer spaced. I belieive that's the case trying to visualize my old one that had the sense wire wrap rotted off and the wiper was jacked too.
 
OK Will byte, educate me !!
Search this topic on aftermarket sender problems, it has been an ongoing issue for years. The fix I believe is either an NOS sender or extra circuitry in line with the aftermarket sender to correct this linear resistance difference. The extra circuitry I
think is called Meter Match. This is the extent of my knowledge of this.
