I like how fast he talks and gets right to the issue ; symptoms, testing, repairs, etc. He's not a slow talker and drags it out. Thank God. 🙂

[WillieGamble]

He gets straight to the point of diagnosis. Then explain how to check the difference issues step by step. Great help appreciated

im sure somebody did mentioned in these hundreds of comments which i have no time to read all, O-rings in modern in-tank fuel pump+filter+regulator, need to be changed as well to reduce/prevent gradual loss of fuel pressure over time and improve fuel pump efficiency(less workload in the long-run). sharing experiences is cool.

Oh my days, thank you for explaining this so clearly! I now feel encouraged to retrieve my car from the garage (what we call the mechanic's workshop in the UK) and carry out this work myself. I feel bad about them charging £210 for an hour of diagnostics, but more than that I feel bad for missing out on the opportunity to learn about the fuel delivery system.

[glennfoster]

Perfect timing for me - am having these issues - great & understandable instruction ! I feel like I should pay you for a diagnosis ♡ you have talent bro God bless

Great video! No ads, no bs, just information as quick and effective as possible

[Dailyfiver]

[dadosytornillos]

VIDEOS VERY HELPFUL. I LEARNED SOME THINGS THAT I THOIGHT I ALREADY KNEW.. HOW AND WHY MEANS. A LOT. I NEVER THOUGHT OF A FUEL PRESSURE REGULATOR... AS. A. CHECK. VALVE. I WATCHED 2 VIDEOS AND LEARNED AT LEAST 10 IMPORTANT FACTS THAT YOU EXPLAINED IN A WAY I COULD UNDERSTAND.. I AM OVER 70 YEARS OLD.AND YOU CAN UNDERSTAND WHAT A BIG HELP YOU ARE. THANK YOU VERY. MUCH.

[kellyfuller]

Lens videos are so informative! I've n ever found anyone on YouTube who explained things more clearly! Thanks buddy love the vids!

[antonioescobar]

From now on I will buy my parts from a1 auto you guys are 😎 🆒️ and have great knowledge

[jonlovett]

thank you for a comprehensive review of fuel delivery fundamentals

[JessNWlfGNG]

I love you man, I know I'm a year late for saving my expedition but fuel pressure or the Fuel pump shat the bed. I had to keep my foot on pressed slightly on the gas, otherwise it would stall.
It's last day with me, it stalled in traffic and thankfully I managed to steer into a side street with no power, everything just shut down so it required some strength to steer that beast.
1999 expedition with the V8 Triton engine. Lesson learned.

By far the best video on Utube I've seen on this subject, Well done 1A Auto and thank you for ALL your videos. Very helpful !!👍👍

[mauricelee]

Dude, I love the fact that you mention a 96 Dodge ram all the time lol. That is the exact truck I am working on.

[believeinfaith]

I love you guys you all saved me thousands! I appreciate your videos and everything you guys do! You guys are a God send to the community that otherwise would be at the mercy of shops paying thousands, of course it helps to mechanically inclined but your videos makes life easier to understand when one has to deal with certain issues., for example me at this particular moment I'm dealing with ., ., .I love you guys! Happy Thanks Giving and Happy Holidays 2023

[drivewaygarage]

Thanks for the video I have a 99 Ram 1500 with a random misfire and it has new spark plugs, spark plug wires and distributor cap so next I'm going to start checking the fuel system
