Start with the connector at the tank, make sure it's not oxidized\corroded\dirty - then the connector behind the plastic inner fender shield, make sure it's not oxidized\corroded\dirty - then the connector in the instrument cluster

justme-

The problem usually is the piivot on the arm in the sender IN the tank- very rarly the connectors- they're weather-pak's.

go to http://dodgeram.org/tech/repair/index.html and look for fuel sender repair.
I have done this a couple of times- drop the tank- it's far easier than lifting the bed.

I just lifted my bed off to get at the top of my tank. This was easier for me because I was doing some welding on the bed. I think the tilt method would work just as well.

When I finally was able to remove the fuel sender unit from my tank I found that it was 'telescoping' up and down inside the tank. I'm not sure if it was supposed to do this, but a few washers prevented the unwanted movement, and now it's working well.

It was kinda disconcerting to pump 160$ worth of bio-diesel into the tank and find the fuel gauge stuck on 'E' for empty!

My advice would be to investigate the nature of the failure before you go and buy expensive parts from the dealership (***********)

Cheers,
Sean.

Sean, I think the entire fuel pickup is supposed to telescope with fuel level so that fuel isn't being picked up from the bottom of the tank.

If you decide to replace the sender it is availible separately from the dealer for around $50. Don't let them try to sell you the entire module for $300.

I had gone through several fuel senders. They seemed to only last about 50k for me. I quit putting them in after the 2nd one and drove by mileage for about 100k then decided it was time to fix it right. I went with a capacitance type sender instead of the stocker. The following link shows what I did and the sender was only about 50 bucks.

Now thats a good link.. heck I might do that myself. I kinda like their gauge though.
Thanks

Yeah Sean, the sending module is supposed to telescope! The problem of the sending unit is the float pivot- read the link in my last post.
The only trouble relating to the telescoping is where then slots are can wear through- then use washers to restore the telescoping ability.

Does anyone know if it is possible to repair the feed and return lines on the sending unit of a 97 3500 Cummins, would be great after pricing a replacement from Dodge.

Many are rotted............

Here's another alternative but someone really needs to talk them down on the price.
Perhaps if they were aware of what the Vulcan costs they would see the error in their ways.

Is there any way to repair the sending unit on a 97 dodge diesel, it is getting air in the line from the tank.it will run for a few miles then slowly shut down

patdaly

Yep, your lines are rotted at the top of the module, get yourself a Vulcan Draw straw.......

There are a couple of ways to repair the problem, both entail dropping the tank , #1 is to use epoxy to seal the lines as they come out of the sending unit { with the lines still on} # 2 would be to replace the sending unit
