[@SyracuseIsOranges]

Homie just skips the whole "dismantle the fuel rail" section

[@MasksOfficial]

Yea it's great when they skip the part that can potentially end in death. Probably the most overlooked thing in the industry especially with diesels. Without releasing the pressure in your fuel lines you can be blasted by it. There was an AA guy over here that died pulling a fuel line off. I cant remember if it was a small nut that blew off and hit him or if it was the pressure of the fuel hitting his arm and getting into his blood stream. Either way it was a freak accident that could have been prevented if he went by the books.

[@Dr.Westside]

@@MasksOfficial multi port fuel injection which is what he is working on only runs at 45psi . Less than the water pressure from the street (55psi) . Direct injection is a different story . There's a Schrader valve on most fuel rails to release the fuel pressure .

If you are even tempted to rebuild a fuel injector you need to already know how to get the injector out.

This guy is the human embodiment of WebMD. “If your high mileage car is running a little low these days, go straight for the fuel injectors! Air filter? Nahh, Mass Airflow Sensor? Nehh, tire rotation? Pfttt, nope.” I would argue fuel injectors, depending on the car can be very time consuming, and pricey, and wouldn’t be considered a quick fix. I appreciate the sentiment, but the delivery could’ve been different.

[@liambradley3997]

Not to mention spark plugs are a much easier fix that cause problems more often

[@mzjoseph88]

Just buy new ones.

[@Sugomis]

Especially pricey on diesel cars, my dad’s mondeo/fusion stopped starting and the reason was all 4 injectors have died - rebuild kits for 100$ a piece and new injectors for 300$ a piece, the car was a rust bucket at that point so it was pointless spending that much money, thoe, I feel like if I soaked the injectors in strong engine cleaning chemicals/solvent overnight it could’ve worked. Yes I’m aware about the whole “you can’t do that the gaps and nozzle diameters are now wrong and you need to code in the injectors after taking them off” thing, but I’m saying it could work in theory.

I have used atf, engine oil,seafoam,silicone, assembly lube, Molly grease. Guess what, they all slid in without pinching the ring, no leaks and some of them have been years. Now if you put it in dry it's likely to damage the seal. Tl:Dr always lube up before inserting.

[@squeekr3843]

Your better off replacing the fuel injector because fuel and other contaminants can get caught in other places of the injector and cause issues later on if you don’t either fully clean the injectors (aka replace them) or you replace them because the plastic slowly deteriorates due to the gasoline digging in and making it brittle and weaker, so smacking it with a hammer can make it break or crack, JUST REPLACE THEM ITS EASIER AND LESS TOME WASTES AND ONLY 5 bucks more per injector ( rebuild kit 5-15$ per injector- new injectors 10-whatever$)

A real legend in his own lunch time! That's not how to rebuild fuel injectors! You only replaced rail and inlet seals and the internal filter. You haven't replaced the pintle, pintle seat or coil. And they, young man, are the components responsible for atomization. Poor atomization of fuel can cause poor running. What you have done would make no difference to running. Unless; the filter was blocked or the rail seal was leaking causing low fuel pressure, also a fire hazard. The inlet seal would cause an airleak if faulty, which could cause poor running. And you should never, never, hit an injector with a hammer! Stick to Lego young man, instead of misinforming the 🌎
