Oil change vac issues with Yanmar

[Valor]

Hey,

I've have purchased and tried 2 different types of vacuum pumps to change the oil on my 3gm30f, and i can not get the vac hose into the dipstick port. I tried going to home depot to find a smaller diameter piece of tubing but there's nothing smaller to buy. So for anyone out there that has this engine, can you please tell me which pump you purchased that fits. Thanks in advance.

Don't know if this will be of any assistance, since I have the Yanmar 3YM20, instead, but I've had good luck with the Marpac Fluid Extractor.  It's a manually operated pump.  It comes with three different size tubes.  I got mine at Defender:  http://www.defender.com/product3.jsp?path=-1%7C2285701%7C2349116&id=1345777

Condition corrected. I picked up a 2 foot length piece of rigid 3/16th brake line and cut the flares off of the ends. It is very pliable and I was able to make it work. The vac I ended up using is the Luiqivac 3 liter capacity.I got it on amazon for 35 bucks. Works great. I was able to do the engine and tranny without emptying it.
