Very informative 👍. Looking forward to see a video on how to do a transmission flush on Elnatra N with DCT transmission.

[@bradley8753]

Plug is behind driver side tire, use a measuring cup to see how much comes out, mine was overfilled from the factory by quite a large amount😶 probably why mine started seeping at 5k miles.. used a hand pump to fill it back up to the recommended level and that's it! Super easy

@@bradley8753 Thanks 👍

​@bradley8753 How much does it take to fill to correct level also what fluid did you use?

[@naveedt9337]

@@CTF33 For my car ( Elantra n with 8 speed DCT), it's calls for tow types of fluid. Wet DCT Fluid and Hyudrolic Control Oil). I changed both oil and fluid and measured the old fluid and replaced it with same amount of fresh fluid and oil. The DCT was not overfill from factory so for wet dct fluid it took about 3.5 to 4 ish quarts and for hyudrolic oil it rook a little over 2 quarts. Hope this info helps.

​@naveedt9337 At what mileage did you change it, did it seem dirty? Where did you get fluid and direct to change?

[@bradley8753]

You left out a critical part of this procedure. You have to check the position of the cam under the pump before installing the new pump.(remove the basket under the pump from the hole with a magnet on a stick) If the cam lobe is in the highest position, it can cause pump failure. If you find your cam in this position, remove passenger tire and drop the fender well liner(do not need to fully remove). Put a socket on the pully that turns the cam till the cam is in its lowest position. Now you won't have any chance of your new pump failing. It's important to note that this is exactly how the service manual says to do it. Personally, I just make sure it's not at its highest point and go with it, and I've never had an issue but to each their own✌️ Ps it also says to use new hardware, buttt I've never done that with no issues

Thank you for the additional detailed information!

[@iadoremelissa12345]

Just got a code for the hpfp and my question is what made you go for the sonata fuel pump and not the Veloster n one? Did you actually notice a different or why did you go this route?

[@nprform]

The Sonata HPFP is an upgrade to the Veloster N OEM HPFP. It allows better flow and reduces the risk for fuel cuts when tuning your car. We just began tuning the car and everything has been running great with the new pump.

[@delasmoo]

Are you getting the recall 262 high pressure fuel pump for your EN and VN?

[@nprform]

@@delasmoo I’m not in the VN since it has an upgraded fuel pump and tune. I’m still debating on the EN. I want to know more about what they are changing to the ECU before I have the recall service performed.

[@delasmoo]

@nprform I was debating too on my EN but was concerned about the safety risk, so I made an appointment. My EN never had any problems though after 25 months of ownership. Now I'm debating if I should cancel my appointment. I was thinking what if the software ECU update causes a problem instead of fixing it.

[@nprform]

@@delasmoo Yeah, that’s what I’m thinking too. I want to make sure they aren’t putting a bandaid on the issue like, detuning the ECU to compensate for the fuel problem.

[@delasmoo]

@nprform If you find out it's a band aid fix can you let me know? That way I can cancel my 8 Nov appointment.

[@nprform]

@@delasmoo If I find something out, I will comment about it for sure.

[@AlanBarratt802Vt]

That's what I should have done instead of waiting on the preorder pump from sxth element the Hyundai N ultra hpfp guess there having issues w it ordered it back in May but guess hyandai doing ecu updates and guess if ur tuned by sxth they will no longer beable to tune the car sence they dont habe the software yet got email lil bit ago

[@dennis_g1562]

Probably gonna be not until the end of the year if I had to guess

[@shamalabadingdong]

I personally do not think this is the way to go. Plenty of people still have issues with this pump Sxth finally got a real HPFP upgrade made by the original manufacturer of the OEM fuel pump. Comparing prices to the sonata pump, it's what maybe $100 more? I'd rather buy properly once than buy something that is proven to not be a reliable fix. They're just around the corner too.

[@nprform]

The new Sxth pump is definitely an option for sure. It’s a difference in price of over $200, not including shipping or tax. So there’s a good difference in price, but for maximum performance the Sxth pump would be a good option. If we have any fuel issue, after tuning, I will make an update video going over the issue and solution.

[@shamalabadingdong]

@@naveedt9337 not the one I'm talking about. Sxth got an actual pump designed by the OEM manufacturer. It's still on preorder. Sxth was just being a reputable seller for the sonata pump before. This is a new upcoming product

[@shamalabadingdong]

@@nprform yeah, I think to me I've seen enough issues to turn me away from it. I've definitely seen some people be fine but imo it's not worth the headache. Any hiccup, stutter, fuel cut you get will have you worrying about the fuel pump. I'm a pretty anxious person and it just wouldn't sit right with me lol. A lot of people get away with worse than the sonata pump (oem hpfp) so there's a good chance you'll be fine but I'd pay more for the headache. If you do run into issues, you'll be down more money once you decide to get the sxth pump, and waste twice your time reinstalling. At least that's my logic. The $200 is extra reliability, power, and a better product + potentially money savings and time savings if I did run into issues on the sonata pump.

[@nprform]

@@shamalabadingdong I don’t disagree with what you’re saying. I haven’t messed with the fuel pump replacement for a tune, so I’m curious to see how it goes. Some say the stock is fine, some say the Sonata pump is required, and some want a pump like the SXTH’s pump. I’m don’t know what numbers we’re going to be pushing yet and I believe that plays a major part of what pump would be needed. We’ll see, hopefully it will be just what we need.

[@naveedt9337]

@@shamalabadingdong Thanks for pointing it out. Didn't notice they launched a new product with higher flow . You are correct, I was talking about the previous OE upgrade not the new one from SXTH.
