Does anyone know what the ohm value is for the fuel sending unit

For a 1989 W250 w/360? I'm having a hell of a time finding the fuel module so I will probably R&R the whole thing. I was going to replace the sender unit in the tank, but I can't find anything, online or local. I guess I can clean it up and pray that it works. Does anyone know the ohm value for the sending unit for this year and model? Thanks!!!

Chrysler and ford use the same values,I know a few people who just used a ford sending unit and adapted it to fit. Here's a link that might help:http://www.fordification.com/tech/fu...ding-units.htm

Thanks!!! I am confused, on the chart:


Ohms/Resistance Popular Models
(Empty/Full)

0-90 Ohms _________________most GM cars, 1965-up
73-10 Ohms ________________pre-1989 Fords & most Chryslers
240-33.5 Ohms______________Industry standard, works on many popular cars
0-30 Ohms__________________most pre-1965 GM cars
16-158 Ohms________________most '89-up Fords



So should I assume a 240-33.5ohm for the 1989 w250 sending unit? Thanks!

No, the 73-10 ohms = most chryslers. Also make sure you have a good ground!

Thanks! I'm sort of in the middle with TBI... so would it be the FI specs?

Thank you! Hopefully I can find an aftermarket/universal sending unit that will work. Any ideas or sources? Thanks again!

You Sir, are very welcome. Like I tell my boys, if you can read you can fix just about anything.

Carb

So I saw your post, so in my case I have a carb, so what does that mean for me if the gauge is only at 10 ohms full but for my carb it needs to go to 5-8?
