Hello Arron,
This sender is a New old stock Mopar replacement that is for sale. It for sale from a site that does nothing but sell factory parts. The part number stamped on the sender itself is 4051003 which comes back as a Chrysler part number.
Of all the reading I have come come across all the new ones are junk due to signal they put out. But I would like to know if this is the correct sender for a 73 Valiant before I purchase it as its not cheap.
