Sending Unit question (68 C20)

[KevinK7]

Short background, my rebuilt quadrajet for the second time now, began dumping fuel all over the intake (infamous stuck float and/or needle). This time I decided to pull the in-carb fuel filter and it was full of 'fibers' and crud.
My initial thought was confirmed as soon as I pulled the sending unit out. the 'sock/filter' was gone, and pieces were in the tank. The (original in-cab) tank itself was amazingly clean.
My truck is an original 68 396 (C20), so it has the 5/16 fuel line and I ordered a replacement sending unit accordingly. I fit right in and line connections were fine.
THEN, I overlooked the wire connection and the photos below show the story.

SO. If anyone has ordered a replacement (5/16 line) sending unit that does have the correct thread/nut wire connection. Where did you source it? (I ordered mine (incorrect connection) through Tamraz).

Also, where are folks sourcing the sock/filter (again, for 5/16" line)?.
My sending unit seemed to work 'OK' so I may opt to just replace the sock if readily available.


Original thread/nut connection:



Replacement 'stud/post' style connection:



Thanks,

Kevin

I ran into the same issue with my 5/16 replacement sending unit from GMCPauls. I replaced the wire with one that had the push-on connector (bought it from member Ironhorse). He has another one listed in the classifieds section right now.

Would it be possible to transfer the threaded connection from your old sender to the new sender?

Classic Parts has a 5/16 sock listed on their website. I have no personal experience with this item.

Or, can you thread the end of that stud so you can put a nut on it?

JEGS Part number 78536 is sock for 5/16th line. Thanks to Mr Mud1, I have one if you need it.

Also, it looks like the post is threaded in, can you just unscrew it and put in the one from the original? (maybe that is what pjmoreland is suggesting)?

Checked the wire he refer to, looks like it is from newer trucks? Maybe able to buy new wire?

Hi Dan.that fuel sock you have is 3/8's but Jegs did have 5/16's as well.Rock Auto had them listed but one or the other I think is out of stock again?.

I ran into the same issue. I took the nut off and put the sending unit wire under it just like the old sending unit. Not the right way to do it but it works.

Thanks all for the replies
PM sent to BigBird (Thanks in advance)
I was thinking of putting the wire under the nut that holds the 'post' in place, thanks guys for confirmation that that is an option.

Thanks again,

Kevin
