Glass Syringe for fuel refilling, this will be handy as petrol distorts the plastic plunger on a normal syringe in short order.

Interesting I may have to look into this , the plastic ones have a way of collapsing when sucking steam water out of the discharge cup.

I've ordered some to try out as getting fuel in the H&M engines is a right royal PITA.

I’ve always wanted to try a glass syringe for the reason Bruce mentioned, but was always too cheap to pull the trigger on one :D
-
I have an old one from a veterinarian's office. I think I could refuel a 747 with it....
-
I use screw top two ounce squeeze bottles with blunt needle tips for fuel, oil, and water for the m91. They work fine, but aren’t graduated for precision dosing.
-
Found another use for the same syringe -

Mine are made in Italy and shipped out of Illinois (2 states away). Cost a little more at $4 a piece, but I try not to buy much out of China

If they are good Nick, I'd like the link mate.

Will let you know right away Jim, just don’t want to talk them up too much if they’re no good... Guess I was wrong on the price of $5.49 (free shipping) but I had to buy 4 to get them that cheap... singles were $9.99
They used some pretty cool looking glass syringes on my wife when she had the last baby, I was going to dig them out of the garbage, but they wheeled it out too fast :D

Ordered 11th Nov and finally arrived today!

I never came back with an update as I was pretty disappointed with the glass syringes... They don’t hold all the liquid in and leak all over the table...

Darn , that stinks 😣

I use a plastic one with the plunger as one piece. The round plastic or nylon end is much better than the black rubber tips that get real sticky with fuel. I've been using it for a couple of years and it is still going strong. I think it is one my daughter used to give measured doses of medecine to my granddaughter. It has a blunt tip needle.

Hi Nick, bad to hear about your glass syringe Leakage....That's not normal for a precision made type..Try to Swap fitting the syringe piston to get a better fit match....tom
-
If you can find an old BD (Becton Dickinson syringes) type, I've always had good luck with them. A properly ground glass syringe should not leak a single drop and should last several lifetimes.
-
My problem is not exactly that they leak... I pull the plunger up, fill it with liquid and as I carry the syringe over to the boiler or burner, the plunger doesn’t stay put and slides back in pushing out the liquid.
-
Here is the best syringe I've ever used for fuel.
My daughter gave it to me a few years ago.
I've used it hundreds of times and it's still going strong.

Yep.....just discovered that myself. The weight of the glass plunger is enough to start it sliding down.
Amazing to look at how well they've made these though, the ground glass finish and fit is exceptional.

Yes, they sure do look nice, maybe it’s just a learning curve...
Did your’s come with an o-ring laying at the bottom (at the end of the plunger)? I assume it was just for shipping purposes to keep it from rattling around as I see nowhere to use it...
-
No Nick, no 'O' ring just the 3 glass syringes in styrofoam packaging.
Amazing they can do all that glass grinding to those tolerances for a buck each.
-
I've got these in different sizes now and they are REALLY good -

Mine were a bit more being made in Italy, but I didn’t buy them for fuel, I wanted to use them for boiling water.
My current plastic syringes hold up fine for fuel, I have had the kind that the black rubber “melts”. But none of my plastic ones hold up to boiling water... the whole thing deforms.
