Lifetime Warranty



Out best-in-class Teltek USA car fuel filter gauge is Made in the U.S.A. and comes with a Lifetime Warranty. A high accuracy vacuum sensor is also included. The gauge indicator light can be set to come on at a certain display reading between 0 - 30"hg. The Teltek aftermarket fuel gauge resets itself after the fuel filter has been changed and begins the fuel restriction monitoring anew. Teltek USA makes precise gauges that will last you through the life of your truck, RV, motorhome or car.

The car fuel filter monitor gauge comes in two bezels, black and chrome. Chrome tends to highlight a truck dash, while the black bezel is more subdued and blends in with the other décor.

The display gauge of the Teltek digital fuel gauge is a large number red or blue LED screen. The LED display is strong enough for the gauges to be read easily in the day time. The fuel filter indicator gauge is simple, durable and precise.

Installation of the aftermarket fuel gauge is straightforward with our included instructions. The fuel restriction gauge fits in a standard truck 2 1/16” spot in the dash and will provide the driver with the necessary fuel restriction monitoring.

Fuel filters screen out dust and rust particles from entering the engine cylinders. Fuel that is not filtered can cause a number of problems in a truck. Debris such as paint flakes or dirt can enter the fuel tank during refueling. Rust is more often associated with steel tanks. If debris in not filtered out of the fuel, the fuel pump and fuel injector may wear rapidly as a result of the attrition caused by the debris on the precise element of contemporary fuel injection. Much like an air filter, fuel filters can increase the performance of the truck by maintaining the purity of the fuel before combustion. A fuel restriction monitor gauge will allow your engine to avoid the problems brought on by contaminated fuel by telling you when it is time for a new fuel filter.

The filter can be changed when fuel restriction monitor light indicates. One can then remove the filter from the fuel line and clean or replace the filter depending on the fuel filter mode. If a fuel filter is not changed, fuel cannot reach the engine at a desired level of flow. Thus, engine performance and gas mileage will suffer. Most diesel engine filters collect water and the water can be let out by opening a tap located at the inferior of the filter. Diesel provides the lubrication in diesel engines, so when water is introduced the friction increases in the engine parts surrounding the water causing wear and damage. Furthermore, water cannot be compressed by the engine and that may severely harm the diesel engine.

Properly functioning fuel filters provide a multitude of benefits: better gas mileage, higher horse power and engine protection. Invest in a Teltek fuel filter monitor restriction gauge to keep your truck, car, tractor or other auto running at peak performance level and protect your diesel engine so it continues to run strong for years to come.
