1967 Fuel sock - needed or no?

[Ara G.]

Hey guys, I sent my original fuel sending unit out to John Wolf for rebuild. Came back looking nice, but it didn't have the fuel sock on it. The original fuel sock on the unit was toast. I called him, and he said he doesn't put them on the units anymore because the current ones come from China and are junk...they break apart with the new fuels and get sucked up through the fuel lines and clog. He said to install it without a fuel sock. Any thoughts? I am using it in an original gas tank. I also sourced an NOS O ring for the unit (will soak it in oil overnight prior to installation) and will reuse the original locking cam. Any thoughts? Thanks so much.....ARA

........ He said to install it without a fuel sock. ....Any thoughts?

None of the 36 gal tankers ever used a sock, and the fuel pump was sucking from the bottom of the tank.

Ara I had the same issue with dads fuel sender we sent to Wolfs. We ended up getting a fuel sock from LIC. Can't say how it will hold up yet seeing how the car is fair from being on the road

Ara:

I agree that having no fuel sock is better than having a cheap one that falls apart. However, if it were me, I would get the GM Part Number and then use their part locating service to find me a real GM/DELCO (NOS) one. I am certain there are still a few out there on dealers shelves. To use the Part locating service, you go to a GM Dealer and have him input the part number into the locating service system. Then they can either order it or give you the ordering information.

Otherwise, install without.

Larry and Ara I already tried GM for a number. None could be found in the states been discontinued for years. My parts guy even looked in there old paper back book.

I purchased the GM strainer (sock) for my '66, GM # 5651702, as recently as 2011, but gmpartsdirect.com now shows that item as discontinued.

Wayne, Very cool pics...as always....My sending unit is already rebuilt, so I guess I will go "sock-less" since NOS ones are not available....Thanks for all the info guys....

Gary, thanks so much for the part number as I was able to find one. They only had one left, but I got it, and it's GM part. We will see when it gets here. Was only 9 bucks, but shipping was 10 bucks....of course it was....lol...Thanks again..

Ara,
I just went thru he!! for 2 weeks because of a stock fuel sock. My car would starve for fuel to the point of quiting and I had a new fuel filter, checked fuel pressure, and fuel lines. Took the carb apart to see if all was well and listened to every other possibility. The car gradually ran out of fuel till it wouldn't get over 30 mph.
Then we both said (TANK) so we dropped the tank and found the clogged sock, broken, and all over the inside of the tank. Part of the sock that was blocking the metal line when fuel was being sucked. All parts of the sock were clogged with what looked like rusty dirt. The tank was not rusted and in great shape other than all the sock pieces.
Today my sender O-ring comes in and NO sock.

Ara,

Based on my memory, those costs are the about same as when I bought my GM strainer in 2011. Also, there was some discussion in 2011 about the GM strainer not fitting tightly enough on the pickup tube, but I found the trial fit of the GM strainer to be fine.

Re: 1967 Fuel sock - needed or no?

I still put on the socks.... but a knowledgeable NAPA guy pointed something out.... For the last 8-10 years the new car makers are not even putting fuel filters in new cars! Let alone socks anymore.
Reason: the quality of the gas has obsoleted them. Now if you had an old tank I would put something on.
Think about how clean and pure the gas must be to run the new complicated cars!!!

Re: 1967 Fuel sock - needed or no?

Your NAPA guy is full of crap. The C-4's thru C-6's we sell definitely have socks & the C-6's now have a micro fine strainer.

Re: 1967 Fuel sock - needed or no?

The last place I would go to find a mechanical or electrical part is some "reproduction" Corvette parts vendor. These tank filters were used on millions of GM vehicles, and I have no doubt you could find one that is built to the GM blueprint from any name brand replacement parts vendor.

If GMPD does have any left in stock I doubt if the are GM-built - just like they haven't manufactured vintage ignition parts for over 20 years.

That's an important part. They are tyically rated at 80 microns and will take out larger particles. The inline 10 micron filters do the rest.
