    hey @ChrisFix do you think you can make a video of a windshield wiper fluid reservoir change?? because my car has a super bad leak and I am unsure on how to fix the reservoir. so please if you can make a video on how to replace the whole system it would be really great. also i am sure all your fans will enjoy it as well :)

    Hey Chris, my fuel pump went bad on my 2002 Ford Fusion. At minimum it would have cost me £250 to get a new one fitted at a garage however with your video, I was able to service the pump myself barely spending more than £30. Absolute legend mate, thanks for the guidance

    12:16 you emptied the gas tank, changed the fuel pump ... but wait... when did you fill in the gas in the tank?
    Or was the car running on air? 🤔

    • Ruan Esterhuizen

      lol was thinking the same thing! but remembered he said try to remove as much fuel as you can, so all I can think is that he didn't remove everything, or he just didn't show that he put the fuel back.

    I've heard from more than one reliable source to go with a factory pump, especially if the fuel pressure is significantly different with an aftermarket pump.

    My thought from the vid before, unhook the fuel pump, maybe have a protected fuel pump from sparks, and pump the tank dry, no crap fuel at all to go in your engine.

    Hi Chris! My truck was running on the freeway and started to loose power till it stop totally... I thought it was low fuell, but I out half tank and nothing... I could read 40 psi and it kept in there... I've checked the relay and replaced it, and after that I've tried to turn on and it didn't work again... I thought it was a bad battery and bad alternator, then I took it to O'reilly to test and they showed me that it was pass the test..and then I got lost... Please, what is your opinion about that? Do you think that my alternator is really bad it can be something different?

    love how you make it so simple and show that anyone could pretty much fix anything by themselves instead of having to go to the mecchanic everytime somethings wrong, which you can never really tell if he's honest or just trying to rape you. so i'll just reccomend your channel to any human being with a car. keep it up dude. and thanks for all the advice

    Worthy of mention, DO NOT use any electric drills or drivers when working on fuel tanks, hand tools only! I know that's how you did it, but it needs said too. Great vids.

    Didn’t you leave the pump unplugged? Before the pressure test.

  • stangmaster 2
    stangmaster 2 Month ago

    My Mustang suddenly lost pressure.
    So I get my gauge and verify it.
    I could hear the pump prime by listening to the filler while my brother turned the key.
    I installed a new pump, but got the same result.
    We put a second new pump in, still no pressure.
    I pulled the pump assembly out again, and checked for a bad plastic hose, but found something else.
    On top of the bucket the pump goes in, there is an inline regulator, a sort of valve with no wires.
    It was blocked, you could not blow air through it either way.
    I bought a new assembly, everything.
    It looked different, but is listed as a direct replacement.
    I think it is an upgraded design.
    No filter sock, the filter is a real filter inside the bucket.
    The car stared right up, and drives a lot better and smoother than before.Idle pressure is 35 psi, and pretty much is in the factory requirements, maybe 3-5 psi higher than when I got the car.
    I will never replace only the pump again.

    Thank you! Thank you! Thank you! When I heard you mention the inertia switch, I remembered hearing that rock em sock em robots spring sound when I was fiddling with my tail light assembly. I just reset it and my problem is solved. Thank you for your great videos. I owe you one.

      Check the second fuel pump relay that gives the fuel pump more correct when the engine is at higher rpms.

    Is that inertia switch in all vehicles? Our van's fuel pump stopped working...
    Oh and what if the fuel tank has an anti siphoning tube in it?

    Also if the fuel is too old it must have to be drained and replaced with new fuel right?

    • anonymous anonymous

      Check if you have one and if it's been tripped. Check Manuals or Google your model and year to know where its located. No,some vehicles have it disabled or removed along with airbags example police,military,ambulance, private security. It could be dangerous if their vehicle suddenly stops or airbags deploy in a emergency or during evasive/tactical driving
