siphon gas for fuel pump replacement .... HOW?

So I bought a harbor freight funnel but apparently there must be a check valve that prevents would be gas thieves

How do I siphon the gas out?

So that I can safely get access to the fuel pump and fuel filter?

Just go in the pump access panel.

I changed both my filter and pump with over 3/4 of a tank of fuel. used a lot of rags in case I spilt anything, took my time and a lot of patience. If your sensitive to fuel (skin), most auto stores sell cheap hand operated pumps you can pump it out into a container but its not needed if your tank is 3/4 or less.


I have a PDF on the fuel filter replacement and the fuel pump isn't much different. Mod Mini on youtube did a great video, links are in the PDF file.

The easy way is to go through either the filter or pump access and use a hand pump to pump it out. Most small hand pumps look like a bicycle pump and only cost about $19.00. They are also good for refilling Gearbox's with!
Or, use a hose and suck/syphon it out through the port, just don't inhale or swallow . Take your time and you wont really spill that much. I replaced my Pump with almost a full tank about a week after doing the filter and it only took 15 mins and no spills or residual fumes in the cabin afterwards.

I did find it a bit of a challenge the 1st time I did the pump. Take your time, you do need to put a bit of weight to bear down until you can get the collar to start. Just make sure you have the tab lined up on the pump body. The next time you need to do it you will be surprised how easy it is, the 1st time is always the most difficult.

This is ****ing ridiculous I'm putting as much body weight as I can inside this shoe box and j can't get the God damn thing to engage.

This is ridiculous by now I could have assembled s2000 that was boxed up in pieces without any labels.

****ing Germans...whether it's an m3 or a mini they absolutely have to find the most retarded methods to do things

If it still wont sit flush, make sure the floats are not stoping it from sitting correctly. What I did was to get the pump (and same for the filter) to sit correctly before I put the collar on. That way, I could gauge how much pressure to keep the pump sitting correctly whilst I then spun the collar onto enough threads to hold it down (the pump will still lift a little), once I tightened up the collar, it clamped the pump down with no issues.


BTW, when I got frustrated, I stopped for a coffee and a smoke (at a safe distance !!), then had another try.

I think I have been doing that.

I'm not messing with the filter as I did receive my new filters yet. I'm just changing out my pump so I don't have to drive my track cars around (CRs).

And I'm compressing the living **** out of the pump but it just won't engage the collar.

I should have known something was wrong when I saw a bunch of videos on how to change the stupid filter but not one person has a clip of how the pump and ring are engaged

From memory, once I had the tab on the body located with the tank, I dropped the ring on then pushed down with my right hand gripping the top of the pump bearing down with a straight arm. Once I had it 99% compressed, I then spun the collar on with my left hand. The only thing I can think of is if the large black seal is sitting correctly as this can mess up putting the collar back on.

If I remove the pump o ring of course everything sits perfectly.

I just can't figure out how the print is suppose to sit which is driving me crazy

My palm is literally throbbing from holding down the top of the pump

the printed part of the seal is down! It did take me a couple of attempts. Once you get it, you will wonder what the fuss was all about. I know I did ! Also, when you change the filter, its actually easier to remove the pump, then remove the filter body from the tank before you change the filter (that's why the kits have two seals).

Did you get an OEM kit?
No personal experience, but in preparation of doing mine I've read multiple issues with people using aftermarket kits on the *filter* and finally giving up and reinstalling the old o-ring, as the new one was too big.
Maybe try with the old o-ring and see if that solves the issue. Assuming it was the pump that died, and not the o-ring.

Actually, they aren't as bad as they seem except for BMW price tags. As I mentioned before, Mod Mini on YouTube has some very good videos on repairs etc that are very informative.

ok it's finally done

So most of the instructions said to seat the o-ring on to the pump body first, is that correct? because that was what I was doing initially

I seated the o ring into the tank side and then fuel pump slipped right in with no fuss...that's annoying!
