Have you tried connecting it up yet? Sometimes a floating ground (earth) can cause issues. You could always bench test it with a 12 VDC power source and a 100 OHM resistor...I keep a variable resistor/rheostat in my tool chest for just such occasions.

We had a discussion about fuel senders some time ago. The point was raised about the OEM sender on the F1 being a "non-standard" sender...something about a heated bi-metal arrangement that did not act like a "modern" variable resistance to ground unit. Maybe some one else who is more learned will chime in...

Sounds like an earth issue. Some of us guys are on Mars and we don't have that issue. Earth your gauge to the chassis or block. Check to see if your tank is earthed as well.
Is the sender an original sender or part of the same kit? Might be an issue there?

I'm having similar issues with my Dolphin gauges and new tank, when I picked up my truck,it was at half a tank. Filled it up and the gauge went to empty, I'm thinking he might have the wires backwards, but I really don't know. Didn't mean to hijack,I just want it back on the road. Thanks in advance, L8R ZFLASH

I'm not sure what year truck you have as it isn't in your signature block but with dolphin gauges you cannot use the stock 48-52 sender. You have to use their sender AND an adapter to match the sender to the stock tank. I think that I have an extra Dolphin sender and adapter. If you are interested send me a PM.

I have a 55 with a ls2 engine and Mustangs Unlimited after market in the bed tank. My problem and ignorance is I didn't know the different ohms needed, looking for a 0-90ohm sender unit. I saw a company in Texas that has a tube like unit instead of a swing one. Just don't know what the guy who is working on it has figured out, I know he's getting frustrated. I sent him this and the other link, hopefully it will be figured out

Hey Bruce,
Hmmm... Sender Unit Issues. I spent some time on that one in the dark past. We had Autometer Gauges
& 22 gallon 70 Mustang Tank. The Autometer (modern gauges) wanted a range of 0- 200ohms to work.
Our '70 Mustang tank sender unit wanted to send 11 ohms to 77 or so. Not compatible.
We took the sender unit back out of tank clipped off the original sending unit & soldered on a universal
sending unit working on the modern range of 0 ohms - 200 ohms. Set the float range to work with your tank & you are good to go. '
Good luck over there!

Now Derrick I think going by Tom's is a splendid idea!
I left my windows as the old crank style - too many painful
posts here on the electric windows & (1) piece glass.
You can help me change out the rear seal on my 351W -
I think I'd swap that one for your electric windows.
An electric lift bed? Kind of like a murphy bed for trucks?
