sampling pump for UOA

[Donald]

I have the Amsoil sample pump and am planning on taking a sample of my ATF today. Do I really need to use a new hose each time? The hose was last used for a sample of ATF. I was thinking of either finding a spare bottle to pump in an ounce or so to clear the line, or pushing a baggie into the sample bottle and pump in an ounce or so, remove the baggie and fill the sample bottle.

Seems to me that even with new hose one should pump an ounce or so out before taking the sample to make sure the hose did not catch some crud while pushing the hose down the dipstick tube.

In this case the ATF will not be changed.

No, you do not have to change the hose. Do the procedure you described above.

Why not just buy new hose at a hardware store and eliminate the chance of contamination? I just paid 17 cents a foot for it there.

Would you still suggest purging the fluid even with a new hose?

I have these 3 month pill bottles that seem to be the same thread as a sample bottle, so I may use them to purge an ounce or so.

Well my hardware store had the 1/4" hose for 12 cents/foot. So add 48 cents onto the cost of my used oil analysis. Will take my sample today.
