So I'm doing an oil change. Get the hose in the fill tube, hook up the air hose and watch the oil start coming up the tube. Turn to get some oil and all of a sudden, I hear what sounds like a bubble burst.
I turned to see the container that the oil dumps in, in an hour glass shape. I thought maybe the line was clogged. But it wasn't.
So with it out of the engine, I turned the air back on, and nothing happened. But within a few seconds, as soon as I drop it back down in the oil, the darn container starts getting thin in the middle.

Anyone ever seen this happen? I'm guessing the container is just too thin of plastic. Even though there's several ridges around it, for strength.


I just checked, and it does the same thing with the hand pump that comes with it.

I inherited one with the business and when All Power went down the toilet I bought another 6. sold 5 to my riding mates cause it really makes oil changing on old Pommie bikes really easy.
I left the original out side for the bulk of last year when I was not doing much and it has suffered from the UV so it is sitting out back now waiting for me to make a new tank.
But I have had that one for 7 years and heaven only knows how long the previous owner had it .
A real PIA cause I used to be able to do 1/2 dozen oil changes a day with the two of them .
Even better cause I had one set up with the 2nd smallest tube for ride ons and the old one with the smallest tube for walk behinds.
came in really handy for degassing polyeurathane before I cast it

Lools like a knock off of a Pela PL-650. I have not seen one of that design that hooked up to a compressor. There is a LOT of external pressure on the container when hooked to a compressor. I started with the little round Pela 6000. Works but roo slow and time consuming for a shop. Since the container kinked it is junk now unless you find a way to splint the outsides so it can't deform.

Once you remove the air line, or turn the valve all, it goes back to it's normal shape.
I've sent an email to EWK, and they responded with some gotcha questions. And this is where I screwed up. I admitted to sucking out oil that was contaminated with gasoline.
So, looks like I'll not be getting a warranty. But, it also looks like I'll be getting the metal one.
I found one that extracts and dispenses. Two way would be easy when there's 5 gallons to dispose of.

looks like the same unit as I am using or a knock off of the same unit.
I asked about a replacement cylinder an they quoted a reasonable price + twice the reasonable price for freight
As it is only a cylinder with flanged at both ends I am looking at turning one up when the big lathe gets commissioned .
I was looking at a length of plastic pressure pipe & through bolting the top & bottom together

If you get some 1x2 sticks the length of the cylinder inside the end flanges and space about 8 of the around it and then wrap the thing top to bottom tightly with duck tape it won't collapse.
