I looked up a fuel sending unit for my 65 and what came up is totally different than what I pulled from my gas tank.

Which one is correct?

Here is mine.

Here is what is listed for my car.
Fuel Sending Unit 3/8" 1963-76 A-Body

This one is more like mine but is listed for a B Body.
Fuel Sending Unit 3/8" 1971-74 B-Body

3/8" is wrong. Unless you are building a giant and/or forced-induction engine, 5/16" is the correct line size. The aftermarket senders don't necessarily look just like the originals. You can still buy a genuine Chrysler sender under p/n 4051 004. The first pic you posted looks closest to most A-body senders I've seen.

Thanks Dan. I wonder what I can get to clean to clean it all up to use?
 
They made many differently shaped pipes for the pickup but they end up in the same place. Your first one (in a 5 1/16" version) would be correct for your car as long as the manufacturer got the resistance right. I had a few that were a bit off and the guage read incorrect. I usually test them and adjust as necessary before I install them.

Dan you are the man. I called my local Chrysler parts guy and i surprised him. Price wasn't bad either $112.00 + tax= $120.00

I just noticed a few days ago that one of the eBay sellers is now offering a "Lifetime" warranty on their sending units (for what it's worth). They also say they test them for proper resistance & smooth operation prior to shipping. The price is in line with most other sellers. Might be worth checking out.

Yeah that is a 3/8 unit and has a return line, mine is a 5/16 with no return line.
 
The one you removed is original to your car. the design was changed to what you've shown just below yours. Those added bends make it a little more rigid so it doesn't rattle against the bottom of the tank like the earlier one did.
 
Other part numbers to keep in mind:

Float: Ford P/N COAZ-9202-B
Strainer "sock": GM P/N 5651 705
Gasket: Chrysler P/N 6031 475
Sender grounding clip: Chrysler P/N 2258 862

Often just the float fails and the sender is still electrically good.

Thank you Dan I will add those to my list and buy lots of spares.
 
I went ahead & ordered one of the 3/8" units a few minutes ago. I plan to replace my fuel line with 3/8" all of the way to the engine. It's probably overkill but I'm an old hotrodder at heart. I'm building a 408 6bbl engine & figure I might as well have the capacity to feed it. I also thought the return might come in handy in case I have any vapor lock issues. It would make it easy to run a return to help keep fuel cool.

Do you have a resto thread here?
 
Will these fuel sending unit and related parts numbers also work for a 66 B'cuda or did they change for 66' ?

The link for the one on ebay in a earlier post should work it is listed for a 64-69 Barracuda 5/16 line unless you need a 3/8 unit for bigger gas lines.
 
To me it makes no sense to get a 5/16 sender if you think you will ever ever ever upgrade your car. Regardless of whether a 5/16 sender will supply most street engines (and it will) the fuel system is almost always the first system that gets upgraded. You can get a nice high quality stainless 3/8 sender for around 75 bucks. Even if you don't upgrade the line to the pump, you can squeeze 5/16 hose over the 3/8 nipple on the sender. I said nipple. Yeah, some people may see it as "riggin" or what the hell ever, but the big sender will BE there when you want to upgrade later. I have a 3/8 sender for my Dart and it's gonna have a slant. I also plan to run a holley blue pump backing up my HP slant mechanical pump. Overkill is what hot rodding is all about.
 
I don't agree. More is not necessarily better. There is such a thing as too much. The fuel pump has to work harder to push (electric pump) or pull (mechanical pump) fuel through a bigger-diameter pipeline, and I don't like electric pumps on carbureted vehicles (discussion here). You say it yourself: the stock-size 5/16" unit will amply feed any but the most radically-built engines. Why futz around "solving" a deficiency that doesn't really exist?
