Fuel gauge issue/question

So I am still having trouble with my fuel gauge following the 90-110 conversion.

My question has to do with the compatibility of a 110 fuel level sender and a 1997 D-90 fuel gauge. It reads full but then will only go down to about 1/4 tank and stay there till the tank goes completely empty. I have removed the tank level sender and tested it from full to empty manually and the gauge acts properly. Put it back in the tank and nothing. Every once in a while it will go to empty but the majority of the time it sticks on 1/4 tank. I was thinking perhaps the arm of the level unit was getting hung up on a baffle inside the tank but I have since made sure that the plunger is indeed hitting the bottom of the tank.

So not sure what is happening. My only thought is the gauge is different perhaps not allowing the reading to be accurate.

Any help would be great!

Thanks

Tyler

How far does the spring on the pump housing compress when you fit it? Maybe the sensor isn't able to go all the way down its scale when its installed and you need to bend the arm slightly to allow for it?

Don't know what your set up looks like so that's just a guess.

Scratch that. Brain fart. Just remembered the sensor scale is on the lower part of the housing so wont be affected by the compression of the top.

That said, how deep is the depression for the pump in the bottom of the tank if there is one? Is the arm level when its at the bottom or does it sit below the level of the bottom of the pump bowl? I would try bending it up a little and see if it cures the problem?

That is a good point. I thought of the same thing but the fact that it has worked fine at times leads me to believe that it might be something else. But I think your idea is worth looking at again.

The fact that I tested it manually and it worked fine points to your diagnosis making sense.

Thanks for the input.
