FJC 2731 Syringe Oil Injector

I used it to take out 4 ounces of gear oil out of my explorer rear axle and put in 4 ounces of friction modifier that I forgot to put in when I changed the fluid. The axle doesn't have a drain plug, so this saved me a ton of work. Edit: just tried to use it again a couple weeks later to take a little oil out of the front axle and the internal seals are like fused with the sides of the syringe. Also, the hose no longer stays on. So, basically it's disposable.

worked great!.....on my 1999 goldwing....without this product it would have been a mess to get the gear oil into the shaft drive due to the exhaust pipe being in the way....also good to have around in my tool bag for other projects.....highly recommend and delivery and packaging were quick and quality.....

My application for this syringe was to remove/replace oil in a TRD (Eaton M62) supercharger on my Toyota engine. The small fill port on the SC is accessible without removing the blower, if you have a vac (or similar method of extraction) that has a suitable extension hose. The plastic hose that comes on this syringe was a bit large for the extraction of the oil, since a smaller diameter hardline is needed to reach into the lower areas in the casing, between gears etc. However, it works very well after adding a reducing (barb-fitting) adapter on the end of its hose, to adapt it down to a smaller diameter hardline. The included plastic hose fits the syringe out-port well, (and stays tightly installed during use) - but its ID is about 5/16". I installed a small brass adapter, (secured with a mini SS hose clamp) and added a soft vac line type of hose to it. Then I shoved a smaller diameter plastic hard line inside of the vac line. This enables it to be used to suck out the last bit of oil from the case. The smallest hard line can be omitted for filling - and the whole rig stayed tightly together while performing the job, without leaking or making a mess. It's one of those specialty items that you may only use a few times - but comes in very handy when you need it!

Works great. No complaints. Used it to suck out clutch/brake fluid. Since brake fluid is caustic I don't expect the seals to last forever. But for the price is but another one day.

Awful! Only works when empty. As soon as you have the oil in it, then the plunger gets stuck and won't move. Total waste of money. Oh, and the measurements wear off QUICKLY when you are wrestling this thing to TRY and get the plunger to move.

It is an oil suction tool to remove the oil from a Pro-Charger brand Supercharger. I was very happy to find out about these tools. The Supercharger needs to have its oil changed every 5k miles. I was grumbling about having to take it back to the shop that installed the Supercharger because they charge $110.00 for 10 minutes work.

Works relatively well. Was perfect the first few uses, then rubber cap on plunger started sticking to cylinder until lubricated and then the tube started to come off mid use and THEN the rubber cap on the plunger deforms and gets stuck upon reinsertion into cylinder. But for the price I got many many great uses out of it.

I bought the wrong syringe but was able to tighten up the ID so that it worked on bleeding my Harley brakes

super ideal pour changer l'huile conique je le recommande

Use it to add liquid fertilizers. Works great

Pretty much garbage. It has the ability to suck up liquid, but won't hold it. After suction, it must be turned upside down. Buy something else
