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

good luck,john

 

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!

Carb= 5-8ohms full, 60-75ohms empty.
F.I.= 120ohms full, 10ohms empty.

 

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

 

TBI= F.I. Yes. These numbers are from my manual.

 

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

 

Coronet, Thanks for the info!! I still can't get use to the new stuff!!

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

 

 

trying to figure out specs for a 88 dodge d100. All the sending units are discontinued and im putting a fuel cell in the bed Of the truck with an inline fuel pump. Need to know fuel pressure for it and ohm specs if you have them sir

 

Do you try LMC truck? I know they have quite a few different ones. They are on page 44 of their current catalog.

good luck

 

I heard somewhere that corrosion gets into the contacts and connectors and kills the signals to the dash. I’m just getting ready to TS my fuel sender issues and that’s where I intend to start. I’m taking the box off so I can get at everything for a 4 link mod anyway... might be a simple fix.
