I guess you missed all the other comments about this. I wouldn't recommend cutting clamps off the way I did; I did it for entertainment. The fuel hose is there specifically to contain fuel so outside of it spraying fuel under pressure, there's no real danger provided you don't cut through the hose. On top of that, the fuel pump itself is a brushed motor that sits in the fuel tank. It doesn't explode because very specific conditions need to exist for fuel to combust. It's not like the movies (did you know a cigarette will not ignite gasoline?).

Hello stone. I'm in process to replace fuel pump on my 08 328i. My question,what's directly behind driver seat. I know pump is on passenger side. Thank you

Do u know if the m54 330 fuel pump is compatible with a m52 323 e45

@@patricioaguayo9088 I don't if you still need this information but it's the sending unit

Lol🤣🤣

Ron Service he don’t know what is doing

But they had had TWO fire extinguishers handy! 😂

🤣🤣🤣🤣

🤣very stupid to do that

That’s because you’re not stupid!

I'd advise most people to use pliers or side cutters. The fuel line is there to protect from outside elements (sparks, heat, debris, etc.) making not as unsafe as it looks, provided the fuel line isn't cut through or melted.

You have to desconect fuel line from the fuel filter first to release the presure lol

Good call! We didn't get those in the US and I tend to forget about them as a result

difficult cold start while no prblem in battery, spark plug or mas.

Dude, if you're having trouble identifying a component.. safe to say, you shouldn't be working on it.

Assuming your car won't start because the fuel pump is dead, it's probably already depressurized. Otherwise there is normally a schraeder valve (like to add air to you tires) on the fuel rail at the engine, which you can use to depressurize the fuel system. Otherwise just be careful to catch the fuel when it comes out.

I did it preventatively, the old pump was still working fine. In my experience, it seems like they commonly fail between 150-180k miles. I actually put this pump in a 5 gal gas can to run engines on a test stand and it failed shortly after, so it was a good call.

Yes, if you're doing this preventatively, you want 3/4 tank or less.

Yes, ideally the tank should be near empty. Unfortunately fuel pumps are often replaced after they fail and murphy's law dictates that's after getting fuel!

@@chesapeakemotorwerks Yeap. I had same situation, filled full tank, came home, and next day in the morning car won't start. Fuel pump died over the night.

Assuming everything is fine electrically, the float is probably hung up. You need to be *really* careful to make sure it is installed correctly and doesn't bind.

Chesapeake Motor Werkes That's what I'm thinking. For example, the gauge says 1/4 when it should say 3/4. I just want to make sure before I take everything apart again. I know there's a plastic base the pump sits on. So it might be touching/stuck on it?

Yes, your float is hung up. There's two sides of the tank each with a float, and the instrument cluster calculates how much fuel is left based on their readings. You can confirm this is the issue by unlocking your instrument cluster and running test 6, although with your symptoms it's pretty much a given. I think I had the same problem on my e39 when I replaced that fuel pump years ago & my friend had the same problem with his e46.

Chesapeake Motor Werkes What do you mean by "unlocking the instrument cluster and running test 6"?

Chesapeake Motor Werkes What should I look for when performing this test, I just figured it out.

240Volts I couldn't help laughing my ass off at your reply, I'm guessing that 240volts might be replying to electric cars because they run way more volts than gas, but I am also gunna assume that you are not an actual mechanic that works in a auto repair shop when you are put in to all kinds of situations where your accually gunna be able to make some money, which when your getting paid FLAT-RATE can be difficult, so now that I got that off my chest , you are right but I have worked in many different shops and dealerships and have never met a mechanic that's works on cars EVERYDAY that would say something like that, and that that it's off my chest I did not intend this post to be rude or put u down, but when I read your post it made me think of the hundreds of millions of times I was working my ass off cutting corners because sometimes you just don't get dealt the gravy jobs that can be done quicker than FLAT-RATE, so sorry for the scolding

Hell...... People need to steer clear of that business as long as Mr. Safety is in charge.

@@bradpowell7931 no offence taken cos it sounds like you had a few drinks under your belt whith your comment. Who the f##k would be that stupid around fuel. Oh that's right renecks.
