2016-2018 Kia Optima High Pressure Fuel Pump Replacement

[@cac2244]

Thank you so much, this tutorial helped me be able to remove the ignition coil under the fuel pump in my Elantra GT (2.0L) 2018 and I didn't want to play with the fuel pump, but you made it so easy and well explained that I was able to do it in minutes.

@@cac2244 Awesome! Glad this video was helpful 🙂

@@terryfelton6851 Sorry for your loss, absolutely you just need the right tools.

Hello, great video. Kia dealership said oil is leaking into my fuel pump and its burning off through the exhaust. I'm going through a ton of oil. But they want to replace the fuel pump and a hose $2280😳 Im fairly mechanically inclined and this looks pretty straight forward with your help. But, which hose would they be talking about?

[@ValleyMobileAutomotive]

@@jeredhinshaw2903 Good question. On the one in this video there aren't any oil lines attached to the pump. Do they have part numbers listed on the estimate?

Replace the positive crankcase (pvc) valve

Hey brother that plastic piece has broke by an accident. How screwed am I? Is that metal piece that’s under pressure got a little bent as well. How screwed am I? Will I need to replace the whole line or is there another metal piece with that plastic I can just replace?

[@ValleyMobileAutomotive]

@@ohhlj2761 You need the inlet fuel line to lock into place. If it can't lock or if it leaks then the line needs to be replaced. The plastic cover I believe is an extra safety lock. The metal line can bend a little but you don't want any kinks. If you have any kinks that restrict fuel flow then it should be replaced. Also kinks create a weak spot in the line that can break under pressure.

[@tristc6909]

I heard we should run the car and pull the fuel pump fuse and let the car shut off to release pressure in the pump. I noticed you didn’t without any issues. Is that a necessary step?

[@ValleyMobileAutomotive]

@@tristc6909 That's not a bad idea to reduce fuel pressure. I would still cover the line connections with a rag while disconnecting them 👍

I have been getting a lot more valve ping, especially cold engine with light it moderate excelleration. As the engine warms, the ping decreases, but it is still there. Also, rough start occurs from time to time. No codes, still good mpg, and some oil burn ( 1 QRT per 2000 miles). Thoughts!!!

[@ValleyMobileAutomotive]

@@billbesser3502 It's hard to say without hearing it. Does it make the noise at idle? Take the foam noise insulator off of the pump and see if it gets louder.

[@billbesser3502]

@@ValleyMobileAutomotive thanks for the reply. To answer your question, it is very loud on cold start. It does quiet down a little. But not what I call quiet. Still very noticeable. Typically, valve ping it either timing or fuel. I run top tier fuel. Tried different octanes, ran chevron injector treatment, and timing seems good. The ping seems like is a fuel starvation issue.

[@ValleyMobileAutomotive]

@@billbesser3502 If it was starving for fuel you would get a lean code. Ping happens because of pre-ignition. Like you said timing or fuel composition. If you had a timing issue you should get a timing code. If you have a scan tool that can read live data look at your knock sensor and ignition timing. When the knock sensor detects a ping it will retard the timing to help eliminate the ping.

[@terryfelton6851]

Is that the same as replacing one in a 2016 sportage

[@Ricsar3]

So...how do you diagnose if it need to be replaced?

[@ValleyMobileAutomotive]

@@Ricsar3 This one was leaking fuel into the oil. The customer noticed poor fuel economy.

[@krystalgriffin3355]

The hard line where the gray piece want come off mine. How do it get off

[@ValleyMobileAutomotive]

The gray piece needs to be pushed in towards the line while pulling the line off at the same time.

When removing the fuel part, I forgot to remove the 10mm bolts slowly and evenly. How screwed am I

[@ValleyMobileAutomotive]

@@JayK-cc8cy You are most likely fine. It's just good practice when anything is under spring pressure to release it a little at a time as evenly as possible. Same when putting it back together 👍

[@JayK-cc8cy]

@@ValleyMobileAutomotive thanks man, really appreciate your service to us

[@NatronFatumallafalla]

Putting new one on does it take time to start car? Or will it start right away...mine isn't starting maybe air in it? Ima wait awhile b4 trying again.....spark plugs maybe

[@ValleyMobileAutomotive]

@@NatronFatumallafalla It will run rough at first until the air is pushed through the lines. It should start within three attempts though.
