2nd Gen Non-Engine/Transmission fuel level sending unit ohms???

[RBachant]

Does anyone know what number of ohms the sendind unit sends to the gauge from empty to full? I don't have any old ones or I'd measure myself. I'm thinking of installing a feul cell sending unit in the stock tank. I want a fix that will not be another band aid, replacing it 2 times a year is getting old.

do you go to the truck stop and fuel there? this has been known to kill the fuel sending units. . You know the ones that flow like 30 GPM?? Those are the pumps I am talking about. if not, then I am not sure what is killing your sending units!

I do use truck stops alot but I also drive about 100,000 miles a year. I know that can't help.

I looked in the service manual and couldn't find any ohms readings for you.

Another thing that can cause the sender to fail is filling the tank to the brim.

Manual says to stop after a maximum of two automatic shut offs.

Taking a wild guess here- which may be of little help, but... .

Most are built to one of two "industry standards" either 33 to 240 ohms or 0 to 90 ohms. Most domestic automotive is 0 to 90.

I'm still not totally convinced they're going 'bad'.



These are metal contacts emmersed in lubricated fuel how can they go bad without shorting out?



I still think there is some kind of sluge buildup where(for the lack of correct terms) the reastat slides on the contacts...

illflem, thanks.

I do top my tank to the top evert time. I'll change it 1 more time and try not topping it off.
