DIY oil change, step by step, with pictures
After several calls & email left not responded.
Pricey part for pricey cars I guess.
I suggest this is the way to go for those who want this part.
I can get mine to suck as long as I'm pumping but I thought that once you got the oil flowing it would continue until it filled up the container.
At one time, I did overfill the MityVac and I think that's when my problem started.
Please make sure that tube is tight sealed in there in that receptor.
I have to physically use my hand to lift the tube in that area to keep the seal while concurrently the suction is ongoing.

...I've had good luck with the 7201 mityvac hand pump/evacuator, shown here:
http://www.mityvac.com/pages/products_fee.asp#07201
The small end of the Adaptor is about 10mm (.39") OD, and the largest tube that came with the 7201 is .41" . So just go to pep boys and get some low pressure SAE30R7 3/8" fuel hose. Use about 3" ... Nice snug fit. Low pressure drop allows highest flow (none of the Mityvac transitions are used) .

1) Which end of the adapter goes into the dipstick tube?
2) What do you mean use 3"?
3) Does the 3/8" fuel hose fit straight into the Mityvac plug with no issue?

2) I was assuming, using the largest plastic tube from the Mitivac (.41" OD), that it (the tubing) would be long enough to reach the dip-tube. The 3", 3/8" low pressure fuel hose, was just to act as a coupler between the end of the tube, and the aluminum adaptor. Test this out, and use more than 3" of fuel hose if necessary.
3) As noted above, the largest Mityvac tube goes in there.
remember to get engine fully heated ( drive agressively safely for about 10+ minutes) or do it when you get back from a purposed drive.
Also note it can be difficuly to remove the Mityvac top to empty canister ... you have the option of pumping the old oil out to a transfer jug of choice.
And, you can dry fit the fuel hose to the small end of the adaptor with small o-ring still on adaptor. Just don't let hose get super cold and stiff.

I'd 1st pull the tube and cut off the end (at same angle as original end) ... mark for cut where it is 1st exiting the fitting. If that does not work, call Mityvac and ask for a replacement for the bad fitting ... I'd expect them to senf it for free. And go for new large tubing.

So not sure what cutting off the end would do?

Sneaky enough, my cabin air-filter and engine air filters were free. Just don't ask me how!
