Product Details

The ACDelco MU1943 is a GM Original Equipment fuel tank sending unit (fuel level sensor) designed, engineered, and tested to the rigorous standards set by General Motors. As a true OE replacement part, it delivers the same precise fit, performance, and service life as the component originally installed at the factory.

How It Works:

The fuel tank sending unit consists of a float connected to a resistor assembly. As the fuel level in the tank rises and falls, the float moves accordingly, changing the resistance signal sent to the vehicle's instrument cluster. This signal is what drives the fuel gauge needle, giving the driver an accurate reading of remaining fuel.

Key Features:

  • GM Original Equipment (OE) — designed and validated by GM engineers specifically for GM vehicles
  • Measures fuel level changes accurately for correct fuel gauge display
  • Manufactured to meet GM's rigorous fit, form, and function standards
  • Direct-fit replacement for straightforward installation
  • Backed by General Motors quality assurance and testing
  • Part of ACDelco's comprehensive fuel delivery component lineup

When your fuel gauge is reading inaccurately — showing empty when the tank has fuel, or failing to respond to fuel level changes — a faulty sending unit is often the cause. Replacing it with the ACDelco MU1943 OE unit restores accurate fuel level monitoring and eliminates guesswork at the pump.

quick easy cheap

FANTASTIC MERCHANT!! Ships super fast (within 4 business days) and also the LOWEST prices on the net. I always compare before I buy and I keep buying from this place! Couldnt be happier, thanx!

I registered & was confirmed, but my sign if password doesn't work. Had to use Amazon to get in to shop.

The absolute best price around by far for the Diablosport Intune. Order left Autoplicity within a day of ordering and they quickly provided an email with tracking number. This company is everything you would expect from a better known store except the inflated price.

Good price and free shipping!

so far so good

Ease to pay with Amazon was great.

quick an easy

You're the only place that had this part in stock. Thanks!

Product was exactly as described; ordering was easy; item shipped quickly with correspondence throughout the process to ensure speedy and informed arrival. Autoplicity was one of the only online providers of the Bushwacker fender flare installation kit I ordered. I would definitely do business with Autoplicity again! Great store!

Always great prices, fast shipping and great communication. Will order again from Autoplicity. Order#17421.
