Lund Impact fuel gauge ?

I am wondering if other Impact owners are having issues with accuracy on there fuel gauge ? I know that for some reason boat fuel gauges and snowmobile gauges are notoriously for not being accurate but it still have a hard time accepting the poor quality. My gauge shows 7/8 when full and 1/8 when half full . The dealer is willing to check the gauge under warranty but that requires removing the floor, I am not sure I want the floor disturbed if they are not going to be able to improve the issue. Is this the normal for Lund Impacts or is my gauge faulty ? My new Ford truck cost a hell of a lot less than my boat and it has an accurate fuel gauge !
Thanks for your input!

One of the inherent problems with marine fuel tanks is that they tend to be long and narrow (like my Rebel XL tank shown below), so the sensor (circled) can be easily off depending on how level the boat is. Take a 2′ level out with you, and see just how much variance in level your hull goes thru, compared to your truck.

You would be better off using a Smartcraft gauge or some other fuel management system, to track your actual usage.

I tried the level trick but it still shows 7/8 when it is full and boat dead level side to side and front to back

after leveling I managed to stuff 2 gallons more fuel in but gauge didnt move past 7/8

Hopefully the dealer can fix it to your satisfaction. There should be a separate floor panel over the tank, so no problems getting access.

My RPM Guage and fuel gauge never really worked on my boat. Rather than monkey with the dealership or warranties I accepted it as a reality of boats. Some people may disagree but that was the right choice for me.

I will say last night I realized I was low on gas. I knew I should have been but forgot until i was quite a ways from the launch. Would have been nice to have an accurate gauge but alas I had fish to catch so I didn’t worry about it.

In my old boat the float/sending unit was in the very back. The weight of the motor made the boat sit ass heavy in the water and the gas gauge was never going to read right. It read full ALL the time.

If you can remove your sending unit from the tank, move the float full range of motion with the key on and see if it responds at the gauge.

This is a pretty good video that explains how the level sensor and the gauge work together.
