When I first joined a couple weeks ago someone told me how beneficial it was to use a 100ml syring, tubing and Terumo 20g needle to do sub q.
I have searched all over and can’t find what I would need to extract the lactated ringers into the syringe and a 100ml syringe with locking mechanism to attach needle to administer it to my cat.
Links to what I need to buy are greatly appreciated. TIA
 
I'm not sure what you are looking for-- I've never heard of using a syringe to administer fluids (the amounts usually required seem too large to make that practical). Here's a video on sub-q fluid administration using the usual equipment:

How to Give Subcutaneous Fluids (Video)

I've only ever gotten the materials from my vet, so I'm not sure if there are other sources-- I'm pretty sure you can buy the lactated ringers solution at a pharmacy but I'm not sure about tubing or needles.
 
You wouldn't want to use a syringe to administer sub-q fluids. A 100 ml syringe would be huge and awkward and make it more complicated than it needs to be. The administration line is designed to puncture the bag.

I get the administration lines and needles from Thriving Pets, and LRS fluids by the case from my vet because she lets me have them at her cost but Thriving Pets carries them as well and sells them by the bag. You'll need a prescription for the fluids, not for the lines and needles. I got a big S-hook - about 1 foot long, the kind for hanging plants - at a garden supply store and hang the bag from the top of a kitchen cabinet.

I've tried both methods, and I personally liked the syringe method better because it is faster ( some cats get restless and it being faster is a plus) and because it allowed me to be more precise in the amount I give, I have to say though that I usually gave around 60 ml

For this method you would need a needle (the bigger the better I use an 18 gauge for this and not the same I will give the fluids with) to get the fluids from the bag into the syringe, you would insert the needle in the same place you would usually insert the line (or if the bag has an extra entry for meds is easier to get through there )and pull the fluid out (just like you do with an insulin vial) , once you've filled the syringe with the fluid you will then change the needle for the Terumo needle with the extension or if you can get them there are some infusion wings from Terumo (gauge 21 ultrathin) that already have the extension included and they are very good, they are usually used for infants IV's and is what I usually use

I also got this photo that was sent to me by with the option of the Terumo needle and the extension, I've never aded B complex to the fluids you would have to ask your vet about it

You use the bulb to compress the regular IV/sub Q fluid bag inside to more quickly deliver the liquid. To measure the fluid volume you can eyeball the fluid lump on the animal or use a luggage bag scale to measure the change in weight.
