3/8 sending unit

[pink panther]

looking for a 3/8 sending unit for my 73 chally.

I have heard nothing good about the reproduction units, so looking for original


are the sending units the same for all years or 72-74 challys only? are all e-body units the same? I will be going to the swap in columbia this weekend looking for one, so if they are all the same it will make it easier.

Scott,

 The 3/ repro's I've seen have all been the same...They have a tube for the return line. I don't think 1970's had this option, but the 72-74 version should.

My original sending unit had a metal strap inside to run the ground signal, but my repro had a blue wire. I'm just throwing this out there as a possible way to tell A NOS unit from a repro.

so Mike, would all e-body from 72-74 be the same? I would just buy a repro, but have heard everyone has problems with them.

Yes, Scott....They would be the same.

As for my previous post, that metal strap I was talking about is actually for the gauge signal. My original had that, and you had to make sure it didn't touch the pick-up tube when installing it or your gauge would read full all the time.   

I don't know how successful you will be finding a NOS unit, but good luck.

Thanks Mike, I just want to find one that works, can old ones be rebuilt by someone?

basically you get what you pay for, the cheaper senders are hit and miss on reading correctly, I have stainless steel reproductions have had no issues with them working properly unless there is no ground. All of the 3/8 senders have the 1/4 Return line.

Thanks Dave, it says 70-71, so it will fit a 73?  I will let you know, if it works that might just be the direction I go.

[mopardave]

it was originally for the 70-71. but yes can be used upto 74. I have 3 in stock

[pink panther]

I will verify that is the exact one I currently have and order from you Tommorrow, do I need to order a new seal and ring also?

[mopardave]

it does come wqith a new seal, ring is not needed unless yours is bent badly.

Dave,
I checked your website and the 318-400 take a 5/16 sending unit, I mic my outlet tube tonight and it is 5/16 with no return.  I know I'm a dumbass, but I didn't see any part number on it just the chrysler symbol.  I have a 73 chally with a 340, so I think the 5/16 is the correct one.  Do you stock it?  My ring is good for now until I try and get it off.

[mopardave]

yep, i have them either way 5/16 or 3/8,  Here is a link

I guess I need one Dave , should have had it sent with the lines 
 I was scared to order one as everyone I have installed has no read correctly & my factory one works perfectly but is 5/16 not 3/8"

[pink panther]

Chryco,
is 1/16th make that much difference from the 5/16th to the 3/8?
