    The seals are probably Viton as they need to resist herbicides.
    Viton and brake fluid dont play nice EPDM for Brakes (in modern fluids) and Viton / Nitrile for more conventional oils.

    Yep, you're right.
    For some reason I thought I used to use Flurocarbon in the concentric clutch slaves in the race cars years ago??
    Obviously not, they would've leaked like sieves ATF/diff/transfer box refill oil pump that's better than Tom Thumb Utility Pump?

    As you say, probably just good old NBR in the old sprayer.

    Exactly what I was looking for…

    Great ideas here. Thank you!

    I’m doing the transfer box oil on my D1 300tdi and the Repco transfer pump I got just siezed up….
    Think I’m off to check weedkiller spray bottles tomorrow!

    You may have been depending on the fluid ATF/diff/transfer box refill oil pump that's better than Tom Thumb Utility Pump?

    For folks still looking for a TomThumb type replacement bottle that doesn't need questionable electric pump reliability .. I got one of these of ebay

    1.5Lt syringe bottle

    Quality is quite good. The additional fittings are of high quality too. Can recommend.
    Much quicker to do, say, a transfer case which needs something like >2lt when compared to a TomThumb type(which I also have).

    Will get at least one other one .. just to save the hassle of cleaning out thoroughly for when doing brake fluid and then coolant .. don't want cross contamination like that .. so easier to have a few on hand.

    I'll supply a picture link for when that ebay link dies at some point in the future.

    1.5lt syringe bottle images.

    If you go to the image link, local stores like Total/Sydney Tools have them too, but having seen one at Total Tools, it's the same bottle, just that the store versions don't have the additional fittings.
    Cheers,
    Arthur.

    Oil transfer pump - good hack with garden sprayer

    So . . . I popped off to Mitre 10 the other day and found an "Earthcore" Heavy Duty 5 litre Garden Sprayer - with Viton seals - for $27. I just took the end nozzle off and used it otherwise unmodified to replace the transfer box oil. Filled it just over 2.3l and pressurised it. The transfer was done perfectly in one shot. Caught the overflow in a big jug - otherwise I didn't spill a drop. It was quick enough without being exciting. Very nice not to be under the car pumping rather sitting to the side giving the pressure container the odd pump.

    For the gear box oil I will have to rig up a hooked spout to hang in the filler, and possibly shorten the whole tube so it flows faster. Will attach the spout from the now dead Repco pump – looks like that will work well.
