I just received a supposed 1968 3/8" GM fuel sending unit that I paid too much for. The box had a GM sticker on the outside. Other than a sticker on the ground wire that says "Service Sender P/N 6428822", I don't see any numbers on anything else. Does anyone know if there are any physical differences between the repo and GM pieces ? Thanks, Ron.

Has anyone bought a fuel sending unit, GM or reproduction ? As I said in my previous post, the only number on the one I bought is a sticker on the wire (6428822). The box it came in has a sticker on it, 6428845, which is the GM part number for the sending unit. I have two different old GM senders (5/16" line) that have "AC" and "MADE IN USA" stamped on the part of the sender that you can see when it's installed in the tank; they also have "90 OHMS" stamped on the (resistor ?) part of the sender. The originals have a black float and filter sock; the one I received has a yellow float and a light green sock.

I'm starting to wonder if I paid $ 130.00 for a GM unit and was shipped a $ 50.00 repo. Can anyone tell me what their GM or repo sender looks like ? Thanks, Ron.

I have an original sender that I removed when I replaced my fuel tank.It has the black float and the filter is black.The resistor has 90ohms stamped on it.The top of it is to corroded to see any markings.I installed a reproduction one in the new tank,and if I remember right it had a yellowish green float and screen.The other difference that I noticed was the ground wire connections were different.The original was welded on the sender and the repo had a crimp style connection.

Maybe go to your Chevy Dealer and order one direct.

FWIW, I bought some 67 RS headlight relays, genuine Delco from a dealership and opened the box to find "Made in China" on them.

Thanks for the replies. I contacted Rick's (I didn't order this part from them) to see if their GM sender had any writing stamped on it; they said that it does not. The picture of the GM sender on Rick's on line catalog looks similar to what I have (float and filter sock color).

I probably should have ordered from Rick's to begin with, but I went with another vendor to save a few bucks, even though I've had trouble with this vendor in the past. That's why I was a little unsure that I got what I paid for.

I bought a new GM Sending unit for my 67 Camaro, it was different from my orginal one. The line coming out of the tank was a lot longer, I had to cut several inches off of my fuel line to make it work. It seems to be working just fine. , I think that I only paid something like $79.00 for it.I don't remember if the sending unit had AC Delco on it or not, but it was in a box with the AC Delco Sticker on it. The relays that Bret mentioned are being made in China & GM is just throwing them in a AC DELCO BOX, The 4 seasons brand are USA made & look almost the same, next time I will go with the 4 seasons ones or the ones from Standard Ingition that are USA made. Some stuff you just can't find that is the quality you expect for the prices We pay

Rons68, tell us who your vendor was who sold you the repo sending unit. I for one don't want to deal with any shady vendors.

After what I found out from Rick's (see my previous post),and from looking at the picture on their website, I feel that what I was sent is what is now being sold as the GM sender. I guess that they're just not the same as the ones originally put in the cars. With that said, the vendor was NPD.
