Wtb axillary fuel tank retaining nuts
 

WTB retaining nuts for my axillary gas tank for a 1970 CST/20. As you can see in the attachment, I damaged mine removing them.

Re: Wtb axillary fuel tank retaining nuts
 

I’m in the same boat. I think at least 2 need to be replaced. I may end up machining some. Let me know if you come up with any extras, and I’ll let you know if I decide to start marching them.

`I needed a set a while back , hung a flag out on the forum and turns out another fellow needed some too. He had good original one and found a machine shop to make a few sets. Turned out real nice and the price was fair. If you run up against the wall I can contact him and get the machine shop info for you.

Knuckle-nurse,
Thanks for the potential lead. I will leave the WTB onb hear for a a week or two. If nothing pans out, I will need the information that you talk about.

There may be demand for these. Notice the other post before yours.

Thanks
Rob

Re: Wtb axillary fuel tank retaining nuts
 

I need some too. Also need the long bolt that they attach to.

Re: Wtb axillary fuel tank retaining nuts
 

Yeah I have a couple of the long bolts that are just rotten beyond repair as well. I was planning on threading some 7/16 round stock and welding the long flat washer to them.


I just got the tanks ready to go in so I need to figure these out in the next week or so. I have a couple of ideas. I’ll update you guys if they pan out, or if they don’t…

Re: Wtb axillary fuel tank retaining nuts
 

I don’t need them but if it helps ill take a set because you never know when you need them

Re: Wtb axillary fuel tank retaining nuts
 

I thought I was the only one who was crazy enough use my axillary tank...guess I was wrong.

Looks like we may need to get in touch with the guy who made the retaining nuts.

Re: Wtb axillary fuel tank retaining nuts
 

Yeah I was shocked to log in and see someone else needing them as well today. I found a couple old threads on them but it’s been a while since I’ve seen anything posted on them.

I wasn’t originally planning on using them but since I built the 496, I’ve decided I want to have more than 100mi range, maybe they aren’t such a bad idea.

I’m thinking I can turn the threaded part of the nut on my lathe and I’m going to attempt to press the washer part from 1/8” sheet using my hydraulic press. Plan B is just turn the flat part too. Either way I’ll weld them together. I’m 87% sure it will result in something useable.

Re: Wtb axillary fuel tank retaining nuts
 

I believe those are 7/16x14- 12" carriage bolts with a special washer. I tried to find a supplier but no luck so far.

Re: Wtb axillary fuel tank retaining nuts
 

Yeah I couldn’t find them either. I don’t see why just welding that washer to the top wouldn’t get the job done though.

Re: Wtb axillary fuel tank retaining nuts
 

That might be the only solution.

Re: Wtb axillary fuel tank retaining nuts
 

Might be a good idea to make them out of stainless.

Re: Wtb axillary fuel tank retaining nuts
 

The nl2 tank is my 2nd favorite option I am shocked the aftermarket people have not reproduced this tank easy to add to a truck that didn’t get the option and looks good. My favorite option cab lights lol:chevy:

Re: Wtb axillary fuel tank retaining nuts
 

McMaster- Carr has 7/16- 14 x 12" stainless threaded rod. I ordered 3 ...will get some stainless domed caps machined up for the top side.

Re: Wtb axillary fuel tank retaining nuts
 

I took mine out and junked them. Thinking who would want these? LOL

Re: Wtb axillary fuel tank retaining nuts
 

Base,
Pleas keep me posted if you are successful with making the retaining nuts.

Thanks
Rob

Re: Wtb axillary fuel tank retaining nuts
 

Will do. I didn’t get a chance to make any of the barrel parts today but I do have a line on a pile of 2” dia 1/8” thick stamped metal discs I’ll get this week. Getting my press to do what I want to those is the only thing I’m worried about. The rest is pretty trivial even with my clapped out old lathe. Worst case is I can turn those discs on the lathe too.

Re: Wtb axillary fuel tank retaining nuts
 

you posted on my thread regarding these retainers a couple days ago. It is clear my parts are not going to give up without self destruction. if you have time and ability, I could use 3 as well. Of course I would like to offer to compensate you for your time and material.

Re: Wtb axillary fuel tank retaining nuts
 

Any update

Re: Wtb axillary fuel tank retaining nuts
 

How many are looking for sets of the tank nuts? I had an OKC machine shop machine a set for me and for Knuckle Nurse. I thought they turned out great. If I can get an approximate count I will stop by the shop and see if he would make some more. I would connect you direct with the machine shop if he is willing. Here are what they look like.

Re: Wtb axillary fuel tank retaining nuts
 

Sir,
Put me down for four.

Thanks
Rob

Re: Wtb axillary fuel tank retaining nuts
 

Can you please put me down for 6. 3 for my tank and 3 for a possible mirror tank of the future.
Thank you

Re: Wtb axillary fuel tank retaining nuts
 

I would take 4.

Re: Wtb axillary fuel tank retaining nuts
 

I too would be interested in 4.
