'66 fuel sending unit

Re: '66 fuel sending unit

Gary, Look closely again. Aren't the white plastic insulators actually threaded nuts? They are on one of the senders I have from a 66.

Russ,

Good eyes. You are indeed correct. The white plastic insulators have internal threads that screw onto the threaded lower portion of the pins. Underneath the plastic nuts are rubber washers.

Scott, The one you show and the one Gary shows are not the same. Gary's has the white plastic nuts and yours are the steel nuts.

Correct. Mine differs from Scott's and Russ' in terms of the plastic vs. metal nuts. The plastic nuts on mine do indeed screw off. Presuming the rubber boots from the wiring harness fits over the pins and nuts, I assume a judge would not be able to see the difference. Yes?

Now does anyone know what year the one I have is really for if it differs from Russ' '66 unit and from Scott's '67 unit? Maybe it's correct for '63 thru '65?

Pictured is an original 67 fuel sending unit from my April build car. Metal nuts. Hope it helps.

Is it possable that 66 used both styles as my original one on my 66 has the steel nuts and the 66 that I am restoring for my customer has the plastic nuts? I can't be sure that the customer car has it's original one but it does have the same stampings. One of these cars is a SB and the other is a BB

Russ,

Can you confirm that once the rubber boots on the wiring harness are inserted over the pins that the type of nut (metal vs. plastic) can't be seen? What I'm basically asking is can I restore and use the sender I have now and the judges won't be the wiser?

Gary, I installed my wiring harness on both styles and when installed you can not tell the difference. The boot does cover the nuts completely up.

Russ,

Excellent! That's exactly what I wanted to hear.

Thanks,

Here's the sender on the last 1965. ie. next tank installed was in a '66 .

Wayne,

That's a great photo. Thanks.

Now I'd like to see a fuel sender for an early '66 to see what it looks like. I always seem to want more data.

Re: '66 fuel sending unit

Here's a pic. of the original for my April 65 car. It's headed to John Wolf for repair. Is there a definitive answer on the plastic vs. metal nuts?

Jim -

Why not ask John Wolf? He's probably seen more original senders than the rest of us put together.

Re: '66 fuel sending unit

If you go back a year or so, there are a couple of threads that identify that there were a couple of engineering changes to the senders in this time period and later for service.

The float, sock, nuts, and isolators are the major points.

The good thing is that the wiring covers the nuts and for those really looking, a mirror into the fuel tank will help you see the float, etc.

Issue is with the data is that for 40 years the service parts which were the latest version are just as susceptible for failure due to corrosion etc. and in need of restoration as an original.

Gary,

Here is what I believe is an original pre-67 sending unit I acquired in an NOS replacement box. It has the plastic nuts:




Here's a picture of my original 67 (June 29th car) sender (on the right) next to a cheap POS current replacement.



You'll note the original has the metal nuts.
