Sending unit for a '63 Valiant Station Wagon

I've been searching for a new sending unit for my '63 Valiant and found two options.

Option 1:http://http://www.classiccarautoparts.com/gastank_sending_units.html
It says there are two lines. What is the second line for? (Can you tell I'm a novice?)

Option 2 is another sending unit that has 1 line....

Any insight is greatly appreciated!

 

Welcome to the Hamb...uuhhh...what is the sending unit for, exactly??

fuel sending unit for a '63 Valiant Station Wagon... slant 6

 

get the 5/16 babe

 

Would it be safe to guess that this is the Fuel Gauge sending unit, that goes in the tank?

 

Will do. Goodbye crappy sediment and not being able to tell how much gas is in the tank.

 

Yes, fuel gauge.

 

Have you tried WildCat Auto Wrecking out in Sandy?? 503.668.7786

...and I agree with 440roadrunner on the return line...

Hey I have the same question...for a 1964.

I had not even done a Google search yet, but I new there might not be a new one made...obsure model of wagon. Hoep there is...

WIll look, but that link you gave in the beginning...no such company.

And I removed the, "...ing units", of course.

www.classiccarautopart.com Nope.

Where'd you find one on a site that doen't even come up?

 

1964 valiant wagon...

 

hey guys, i got my sending unit from laysons restorations. i went with the 3/8" sending unit in case i ever go with a big block. i also have a new gas tank and all new fuel line from the tank to the carb. and my gauge works intermittently. there is a fix for that though. what happens is the voltage limiter for the gauges (which is located in the fuel gauge on these early a-bodies) go out. there is a company that sells a solid state voltage limiter that will fix the problem. they show you how to get rid of your old one and wire up theirs.
here is their link:

hope this helps.

 

oh, by the way. my sending unit had two lines. original one had one line. the other is for a vent. i just caped mine off. here is a link to my build so far.

single units are usually for non ac cars, and yes they are a return or bypass type vent.

 

That's not a real link (??):

Vans Auto has a 3/8" one for '63-'76 A-bodies for $50. That's where I got mine.
