Help! Need fuel gauge sender unit

Boy it's nerve wracking not to know how much fuel you have left. I finally got the tank down and took out the sender which failed, but I can't seem to find a direct replacement. I'd prefer to keep my current gauge in the dashboard too. Does anyone know where I might find one of these things?

I found one that fit well on our pickup tube unit. The one I found needed a new gauge to work.

In looking further into their product line it turns out they have one that works on a compatible voltage/amperage to our original gauge.

Be sure to follow the mounting instructions carefully as you do the measurements at the mounting point on the tubes. A little off on the mounting position makes a big difference at the gauge.
Oh do take care when remounting the tank not to pinch the hoses between the tank and the crossmember of the frame.
You can guess how I know. :-(

Cheers Richard

Richard,

Do you know the part number that would work with an 1986 345 fuel gauge? I'm using 345 gauges in my Argosy rebuild.

Hey Brad, here is a link to the company site.
I have been looking around but have not found much product info right now.
I think our gauges need the 0-90 sender. It was not available locally when I needed it.

I'm pretty sure if you send them the details of our requirements they will steer you toward the correct unit for your needs.
It's the same type that I used, just set up for the correct amperage.

Sorry I'm not a great note taker while doing these jobs.

Richard, Can you give me the part number for the direct replacement sender? My resistor is shot and I can't get the ohm reading for what it should be. Thanks.
Rod

Hi Roddyy. If you have the airstream manuals the details of the sender and gauge are in there. Find that and shoot an email to the link I posted earlier with the info. I'm sure they will come back with the part you need.

I'm taking a quick break while draining oil from the S C. And want to get back to that.
If you do find the correct part #. Please post it here for others. I should have done so when I came across it while doing the job earlier.

Let us know if you are unable to find the info, I'll look into it when I'm free.

Cheers Richard

Thanks Richard, a little research seems to indicate the 0 to 90 ohm is typical for GM vehicles from the 60s to the 90s.

Yep Brad that was my vague recollection from when I was into that project.
The 0 90 ohm. Sender part # is R8926

Perhaps some checking to confirm the info is in order.

I was doing this on the third tank drop in a week and a day after I had planned to be heading for the coast, so went with what I could find locally.
The sender unit itself is a good fit with the pickup tube assembly that came with the original tank. Bolts right to the tubes. Getting it placed correctly is essential to the gauge registering accurately. They included good instructions about taking measurement to get it in the right place.

Cheers Richard

Another thing to check out while the tank is out is the condition of the seams of the tank. On mine there were weep marks in a couple of spots on the side of the tank, from the seams. I had noticed fuel fumes around the back of the coach. And these weeps were a likely source. Lots of prep and ventilation for the tank and off to the welder to weld all the seams of the tank. They were rolled pressed originally.

I also replaced all the fuel lines to the engine and generator while in there.

Cheers Richard

Thanks for the part number. I need to verify the gauges I have use 0-90 and I'll be all set.

Thanks!

Brad

While my tank is out, I might want to replace the sender unit, but mine has fuel feeds and returns as well as what I think is a feed for the genset...



The one mentioned does nott appear to have fuel feeds/returns...

I will pull it out of teh tank tomorrow and hopefully find a part #!
