I'm going to be putting in a fuel cell and I want to know what ohms the sender should be as I want to use the stock gauge. Seems most of the senders that come with the fuel cells are for GM 0-90. Anyone have any information as to what sender I would need for my car? 66 Sport Fury, with 440 if that matters.
Thanks guys....
 
Dang, I knew that once, but now I can't remember the answer - nor where I found it. Seems to me though it *may* be the reverse, at least something I was looking at at the time was. For some reason I'm remembering something that was around 80 to 0 or thereabouts.
 
Yeah I'm thinking it's backward too, like 70 empty and 10 full, but not sure. Gotta get it right. I'll give Summit a call if no one chimes in.
 
Just checked both a 65 and 66 FSM, neither has the answer, both specify the same tester to check gage accuracy.
 
I'm going to go with the 0-90 GM sender and the 16 gal fuel cell with foam and just purchase an Autometer fuel gauge to go along with it. Much easier this way and the cost will be cheaper too.
 
look at summit or any other place they sell guages, if I remember correctly ford and chrysler are the same. The decsciption should tell you. I have the same problem. I am putting a fuel cell in a 64 chevy truck and the ohm range is different. seems like the quickest and cheapest fix is a aftermarket guage.
 
Yeah, this is why I'm going with a new gauge. Simplest fix really. No worries either. Mount it up and forget about it.
 
There is a company called Redline Gauge works that can convert your factory gauge to work with the sending unit that is in the fuel cell. I will be having them do that on the 65 Fury I just bought. they can also convert your ammeter to a volt meter to reduce the possiblity of fire and major failure if you want.
 
Most after-market gages today have ~4 range choices, and one fits Chrysler & Ford. The manual below (posted on A-body site) says 10 ohm full, 73 ohm empty, so Alan was real close. Indeed, most people say 90 ohm empty. I was just testing a new sender for my 64 Valiant on the bench and adjusting my fuel gage to match (cluster out). I recall measuring 90 ohm empty, 9 ohm full, at full travel of the sender arm not necessarily where the float will stop in the tank. Mid-way is ~25 ohm.
