I wanted to give another update on my new fuel sending unit.? Even though the gage read close to what I wanted with the tank full and 5 gallons in the tank, I found it was not very linear.? It would drop down fast initially and then slow down after 3/8 tank or so.? I was not comfortable with that, so I decided to take my old sending unit apart to see what was going on in there.

I found the metal strip that slides across the wire winding was worn through and the end was just barely hanging on. I removed the hanging piece and bent the metal strip so it would contact in a different area.? I then made sure it had pressure against the wire windings.? I tested the ohm readout and it functioned very smooth and transitioned through the ohm range very uniform.? I had tested the repaired float and filter by soaking in gasoline for a week.? They both passed but I did not like the looks of the filter.? I figured out how to remove the filters from both the old and new sending units and swapped them.? I thought about swapping the floats but decided to try the old float first, at least for a while.

With the gasoline drained from the tank I installed the old sending unit and was getting a reading over E on the fuel gage.? I adjusted the float position by bending the float arm until I could get a reading of slightly below E.? I then tightened the sending unit lock ring and put in 5 gallons of gas.? The gage read just below 1/4.? I then added another 2 gallons and got a gage reading of just over 1/4.? When I filled it up the gage read slightly over F, which is what I am used to seeing.? After driving about 10 miles the gage was on F.? I think it should continue to work well. ?

I will continue to observe the gage reading when the tank is full to determine if the float is soaking up fuel.? I can always swap the float from the new sending unit if needed.
