What's Inside An Electric Fuel Pump? - EricTheCarGuy

Hanging out with the head of engineering was a real treat, he was kind enough to make this video with me about the different parts inside a fuel pump. It was also great to learn about the different types of fuel pumps that Airtex makes.

@knunne1 Thanks for that great comment, I'm actually looking into going back to Airtex to do some more of these videos so that is one request I hope to fill.

Very detailed explanation. I’m sure there are a people who are interested to learn all about electric fuel pumps. It’s hard to look for videos like these so thank you for uploading it and satisfying people’s curiosities.

[bifulcog]

You explained all components and functionality in under 10 min, and most importantly you answered all my questions.... Well done sir!

[ericthecarguy]

@TheTexasCoder That is very true, I like to get my info from the source whenever I can and this guy is about as close to the source as you can get from what I've seen. Thanks for the comment.

[hayksamvelyan]

This is why I love your channel - very educational stuff, and you don't try to dumb it down like some other shows do.

[ericthecarguy]

@pathosbedlam Your most welcome and thank YOU for the comment.

[ericthecarguy]

@1967800 That is the exact reason for these videos. Thanks very much for your comment.

[ericthecarguy]

@aodhanof90 It's nice to get information direct from the source. Thanks for the comment.

[ericthecarguy]

@barrioalto100 Glad you like them, thanks for the comment.

@brian5446 Either that or you can just cycle the key before you crank the engine when you go to start the car, I did that for years on a car that I used to have as the pump still worked fine.

This video defiantly confirms that I have a fuel injector problem with my truck and not a fuel pump check valve problem because of the bleed off time that my fuel pressure gauge was showing. When I tested my truck the pressure bled off immediately after shutting the truck off.I'm looking at getting new injectors and I know now its not the pump.Great video Eric and thanks for all the info.

[ericthecarguy]

@95ACM It's a common problem but as you can see the pump will still function without it but it will cause extended crank times.

[ericthecarguy]

@Begbucks Yes they did have a very extensive diesel section at the facility, I didn't spend a whole lot of time there on this trip, perhaps the next if I get the opportunity.

[ericthecarguy]

@alundrasrt No need to worry about that as the pump is submerged in the gas in the tank which is what 'lubricates' (if you could call it that) and cools the assembly, priming it is not necessary at least with the pumps I've installed.

[ericthecarguy]

@nightmathzombieethan Indeed there is, thanks for the comment.

[ericthecarguy]

@1PossumJenkins Great information thanks for your comment.

[ericthecarguy]

@DrJerryrigger I do what I can, thanks for the comment.

Thanks to Airtex and ETCG for a great video. I am amazed at how, what is basically plastic and a motor can deliver combustible fluid so reliably. Hats off to Airtex's Engineering & Production's teams and their quality! I am guilty of not recognizing how hard and trouble free fuel pumps work. I enjoyed seeing how the Car's trouble symptoms related to the components in the pump and the various versions made as well as how they are tested. Again Great Video, more please!

[ericthecarguy]

@Bushougoma No, in fact the fuel flows right through the pump. Remember in order for combustion to take place you need O2 and if the pump is full of fluid there is no O2 for combustion to occur.

[ericthecarguy]

@MrOne2watch It does sound like a possible check valve issue but use a fuel pressure gauge to confirm it. As for Airtex pumps I've never had a problem with them. I don't have a video on that particular replacement at this time sorry.
