Default Re: Adjusting Fuel Level in King Seeley Gauge

Last year I never got above the 5/8" mark when full, Same experience as JimG.

I find it hard to believe that when new the fuel gauge never worked properly.

Mine reads perfectly now but never used to go over 5/8 full.

There are three possible reasons for this and mine had all of them

First problem is if, on the sender in the tank, there is a leak from the top cup then it won't go much above 1/2 full indicated

The second problem is if there are to many calibration rods in the gauge - I removed 6 from mine. With that many rods there isn't enough room for enough fluid to ever read full-I have one rod in mine now and as I say reads perfectly

The other think which I believe is relevant is that the aftermarket tank needs an adaptor to use the original fuel gauge I think that this lifts the sender higher and hence you don't get a full indication. I fixed this by getting an old rusted out original tank and cutting the gauge mounting part out of it (the top rarely ever rusts ) and welding it into a new tank

Such a fine sight to see-Its a Girl, My Lord, in a Flatbed Ford slowin' down to take a look at me.
