How EFI Fuel Pumps Work

[@Hunting_Party]

Lol it’s good to know that even papadakis drops stuff on the ground and has to crawl around to find it.

[@LUISIONFUSION]

At least his floors are white so they're easy to find

[@MadsKongsved]

And there’s the reason for having a clean workshop ;)

[@alekseykuleshov111]

His workshop is way cleaner them my living room

[@TRACKMKIII]

Lol!

Lol

[@MrTrev69]

No disassembly is complete without a search for the jeeesus clip

[@bunnythekid]

@freezeme360 a personal favourite is the hell spring. Small enough to to hide in shop dust. Large enough to fly across the room and land, apparently, in another dimension. Rumour has it you can place a 10mm socket under your pillow and a fairy will find it for you overnight

[@newjargon1697]

Jeezless!

"Want to see me teardown other stuff?" Uh yes, basically anything. I'll watch.

[@Garrett_LCD]

agreed, open up anything and everything engine-related. Maybe a power steering pump or AC compressor next? Different variable valve timing setups?

[@MuffinKingStudios]

Yeah, I want to see everything. My suggestion is maybe an AC compressor or a electric bypass exhaust?

[@TrevorDyck]

Yaaasss, tear down all the things

[@Jellegerritsen]

Mabe the electric power steering

I appreciate that papi papa isn't just a big wig in an office but actually knows the ins and outs of all his cars.

[@andoletube]

I think he's the exact opposite: totally involved with every aspect of his cars' development. Great knowledge and a great teacher.

The end of the video is a classic when you are dealing with screws and that kind of clips, such a relief when you find them 😂

[@mohsentabouna6401]

great video, I love how you go into details because many of us here are a little more than amateurs and as myself there are plenty of engineers I wish you tear down a high end turbo+waste gate and expose the technologies involved

Just watching your videos you've taken away the fear of working cars being so complex. These videos make me want to learn more and do more with my own car.

[@Buwtz]

More teardowns!!!

[@ibrahim-sj2cr]

loved the end bit. the blessing of working in a clean shop is finding dropped nuts and bolts

[@Mistah242]

Tear down everything! Love seeing tear down videos by experts.

[@TheFogmachine803]

Yeah those e-clips like to fly off into the ether in my shop LOOOL

[@craigbarrett2278]

In 1994 I had a 16v Golf 2 which ran a Bosch high pressure pump like the one you opened. A fitter and Turner friend and I opened it up and serviced it.......car ran another 180 000 km on it. He started a successful business doing repairs!!!!

[@mattchew5014]

Love teardowns of anything automotive oriented thanks for all the awesome content.

[@samwu8070]

Thanks for the tear-down video. I'm happy to see the structure inside. I wonder what's the common problems that the pump fails.

[@lewisbiggs5977]

Like everyone else says, it's so good to see the boss of a race company doing this sort of thing, it shows us you're a true car nerd, and that you're aware that all us amateur car nerds want to know this sort of stuff. If you are able, please keep going with tearing down things that we don't usually get to see!

[@seanschackier577]

Didnt find a 10mm while looking for that e clip did you?

[@Mopar_logic]

Lol

[@gtsporttour506]

Pap works on BMWs now... No 10mm needed. 😁

[@fnymn1]

Thanks for sharing Stephan, I would have thought AEM used a brushless motor but guess the engineers have their reasons. Also like your teardown video's keep em' coming!

[@TML34]

I love how clean and organized your workshop is. That’s the first thing I look for when I take my car to an Indy mechanic.

[@hoedenbesteller]

I just love how the floor and workplace in general is really clean. So that also you can still find your clip when it decided to go on a field trip

[@miamatti]

Great demo of Hydrostatic/dynamic pumps and their differences

[@vuifong8008]

The fuel injector, small cc to large cc.

[@kylehufford9645]

Came here to say this, maybe also include port vs direct injectors

[@kimoarmstrong3519]

It is a lot of fun to break things. It's less precise than making things. It's like therapy.

[@oscarsmee7737]

Can’t get enough of these videos. The cleanliness of the workshop always makes it for me! 🤤

[@ALWhiteAuthor]

Oh man... the flying E-clip. I started racing RC back in the 80's when they used E-clips on everything. I feel your pain trying to find that damned thing. Seeing the armature from that larger pump takes me back to the days of the Hudy Commutator lathe and cutting motors between rounds and tuning your brushes for the perfect amount of contact pressure and timing.

[@BenSmithHuugs]

Tear apart a break master cylinder! Or a shock! Love your videos, thanks for the amazing descriptions and awesome quality.

[@ibrahim-sj2cr]

yes please more tear downs and deep explanations of how stuff works

[@bobqzzi]

Used those pumps for years, but never took one apart. Very cool. Thanks

[@jsquared1013]

That brief pause when the C-clip launched itself, I've felt that same feeling before 😆. Great videos. This is one of the best channels for mechanical geeks like me.

[@EndriuGolara247]

Great video Once I melted my fuel pomp bracket because I run on 1/4 tank for months and it wasn't enaugh fuel to cool down the pomp.

[@isaakstagl3749]

I have been watching your channel for years and always enjoy listening to your perspective on these things. I would definitely want to see more videos like this, where you explain the inner workings of how these things work, or how you build your racecars

[@RossOgilvie]

Best KZbin channel for car geeks. Great work Steph 😎

[@henninghoefer]

Your videos are absolutely amazing: Short and to the point and yet I always learn something. Thank you so much!

[@shinedowncannel]

Interesting. I have disassembled a few pumps for fun and this is what i found. Bmw E30 318i: roller. Audi C4 V6: turbine. MB W210 V6: screws, like the pasta screws.

[@Flashbang_Photo]

In spanish the literal translation is endless screw, i don't know if it's just like that.

[@andreacicerale192]

The entire electric motor is sorrounded by fuel Me: 👁👄👁

[@hojnikb]

This shocked me as well. But it makes sense.

[@AlanTheBeast100]

Shocked me a bit when I learned about it a few years ago. Honda recently had an issue where, in the pursuit of energy efficiency, they ran the fuel pump at variable speeds according to flow need. With some fuels this would cause sulphur build up in the motor and then pump failure. So a software fix was put out to increase the minimum speed. further, fuel carries away heat from the pump motor as well as lubricate and I assume clean it from commutator dust.

[@gilberth8944]

Very informative for ppl who cant break apart parts👍

[@gwot]

yes please! more teardowns for misc parts! It was interesting to see the inside of a pump, although it just turned out to be what I expected. Thanks!

[@autofixation]

Awesome video, you explained so much that I've always wondered about. I would like to see you year apart a power steering pump, and a rack and pinion to show how steering works on modern cars.

[@remlapgarage]

I literally did a how do fuel pumps work search last week, thanks for the tear downs, exactly what I wanted to see :)

[@Chiaroscuro22]

The fuel flows over the armature. Fuel is non-conductive. That’s amazing - I literally had no idea.

[@curbyourshi1056]

You're a super knowledgeable man, Mr Papadakis, with an excellent, relaxed presentation style that comes with that knowledge. I enjoy all of your vids, even though I don't need to know any of what you show me as I don't have the £££ to modify or even buy a sweet car. Definitely interesting though. Totally subbed.

i think a teardown of different types of differentials would be cool. the disk, the cone, the torsion. or a teardown of different types of transmission. typical 5-speed, dog box, and most importantly show the power flow inside the transmission.

[@phunkpup]

Would love to see a single, dual, or maybe even triple damper teardown side by side. I know the triple would cost a lot but one can hope you've got some fully re-buildable ones hangin' out

Watching you look around on the floor for the part reminds me of the mistake some people make when painting the floors of their shop. Never put those flakes in the paint, you cant see any small parts against the backdrop of those flakes. Charles
