That's it, I've had enough. Has anyone ever managed to get those brass hand powered oil extractor pumps to work? Pumping like a lunatic and nothing, tried priming by sucking, big mistake. When it does fill it is like pumping mud, even with hot oil. Then when it does come out if flies all over the place like a mad mans sh*t. I'm off for one of those jobs with a white built in container. /forums/images/graemlins/mad.gif
 
Yes, mine was affected by the oil.... the rubber on the end seal where the pickup pipe is fitted had expanded slighly as a reaction to the oil I presume so a cable tie around the rubber restored the seal and pumping action back again.
It is a poor design to say the least, from what people say the Pela is a better device although a lot bigger.
Happy pumping
 
I've had the same experiences. Go for a vacuum extraction pump Pela or similar. Cheapest I've seen is compass.
 
Not sure this will help you but yes, my brass pump does work pretty well. It's just the standard cheapo version and doesn't need any special priming. Working it slowly helps in terms of avoiding oil splashing - I put the outlet into the top of an empty water bottle and fill a couple of those. Lots of newspaper on the floor to catch the few drops of oil that do spill and it's pretty painless. Need to check that the thin pipe inserted into the sump just reaches the bottom and doesn't bend and then curve upwards.
Also, I guess if you have a lot of old gunk at the bottom of the sump, then it may be more difficult to extract it.

Maybe you are pumping too fast / hard?
 
Although mine looks like it has brass bits on it, I think it is just about 100% plastic/rubber. Cheapest on the market at the time and has been faultless. So far about 14 years old.
 
Never liked the brass pumps. I had a fixed one on the last boat and as you describe, it was like pumping mud: very hard work. That was with the oil hot. With it cold it was impossible. With current boat I inherited portable one, not the cheapo version though. Leaked oil from the top round the plunger. When it worked at all. Bought a cheapo. Still got covered in oil from leaks.

Last year I bought a vacuum type. Great idea. Used for lots of other jobs as well.
 
Comes as part of the package on a perky.
When I first bought the boat it felt like I was dredging the marina. However, a few oil changes and repair of the leaking water pump and we're back to what it should be.
If your oil is worse from the boat engine than it is from the car, should you not be asking yourself why???

Agree with the other posters here - Get a Pela pump - don't get the spherical one, spend a little more and get the 6 ltr tall round one. REASON: it has a slightly wider bore in the suck pipe, which means it can be used to suck up water from awkward bilges as well. Also makes changing the oil a doddle.

One other thing - take the old pump back and get you money back..... It seems we all have had the same experience with them.
 
My investigations into the poor performance of my brass pump showed that there are two valve types. The one I had, that failed every time I wanted to use it, had a flap valve made from thin rubber or plastic sheet. After being used it seemed that the oil reacted with it and it warped, making sealing impossible. Each time I used it I had to mould this material to get it flat again.

The other sort, which looks exactly the same, has a ball bearing check valve. This works perfectly every time. The only way to tell them apart, other than disassembly, is to rattle it. The ball can be heard shuttling up and down, whereas the flap valve is silent.
 
I have the Force 4 spherical type and it is perfectly adequate for emptying difficult to access spaces/ bilges etc. One of the most useful bit of kits I have ever bought. Buy one or a Pela - you will wonder how you coped before...!
 
I have a brass pipe plumbed into the sump of my Betamarine. Yes its easier to pump out when the oil is warm but its not impossible cold and it doesn't take long.
One reason may be that the feed pipe is large compared the little pipe that will go down the dipstick hole.
There are usually several sizes of pipe supplied with the kit. Are you using the biggest possible size?
