Fuel System

As the Hyundai Genesis Coupe ages it is important to pay attention to condition of the fuel system. Often upkeep of the fuel system gets overlooked. Do you know when was the last time your fuel filter has been replaced, if ever?

The fuel pump and filter of the Hyundai Genesis Coupe sits inside the fuel tank underneath the rear seat cushion.

When it comes to modifying your Hyundai Genesis Coupe replacing the fuel pump for an aftermarket high flow fuel pump should not overlooked when trying to achieve high horsepower. 

Removing the Fuel Pump Assembly:

Make sure the car has less than 1/2 tank of fuel when doing this.

Remove the rear seat cushion.

Remove the service cover of the fuel pump.


Disconnect the fuel pump connector (A).


Idle the engine and wait until fuel in the feed line is exhausted.

After engine stops, turn the ignition OFF.

Disconnect the fuel feed tube quick-connector (A) and the suction tube quick connector (B).

Remove the bolts (C) that hold the fuel pump retainer to the fuel tank.

After the bolts are removed you can lift out the fuel pump. Do not forgot the orientation that the pump was facing when in the tank. It is possible to install clocked to the wrong direction. 


Be very careful of the fuel level sensor. You will need to lift out the fuel pump assembly then tilt it to get the fuel level sensor arm out safely. 

Some fuel may spill out of the fuel filter assembly. Put down a fuel resistant material in the interior so you do not spill any on the carpet. 

The fuel pump assembly sits on top of a rubber o-ring that is on top of the tank. Do not misplace that.

Replacing the Fuel Pump: 

Disconnect the electric pump wiring connector (a) and the fuel sender connector (B).



Remove the fuel sender (C).


Disconnect the fuel feed line (A) from the fuel filter.


Separate the head assembly (B) with the hooks (C) released.


Disconnect the regulator hose (A) from the fuel filter (B).

Separate the fuel filter (B) from the reservoir (D) with the hooks (C) released.


You will now have access to replace the fuel pump and the fuel filter. 

Installation is the reverse.

Removal of the Sub Fuel Sender:

Remove the rear seat.

Remove the service cover for the sub fuel sender (Passenger Side).


Disconnect the sub fuel sender connector (A).


Disconnect the suction tube quick-connector (B).

Remove the sub fuel sender from the fuel tank after removing the retaining bolts (C).

Be careful removing the sender as to not damage the fuel level arm. 

Replace the pickup sock if dirty.

Awesome Service

I recently purchased the ARK test pipes for my 2010 Hyundai Genesis Coupe 3.8 and must say was the best thing I’ve done aside from from getting my aftermarket exhaust. Sounds louder and drives faster! No hassle, got the pipes within three days. Thank you GenRacer,

Simply the Best Service

Most places just sell parts and when you call them it feels like you are bothering them. My last transaction with GENRACER left nothing to be desired, meaning it could have not been better. I purchased front and rear WHITELINE sway bars, front & rear DBA rotors, and EBC YELLOWSTUFF brake pads. I called just after I ordered the parts because I received an "out of stock" email notification. When I called back to chat with someone *** answered the phone. He couldn't have been more knowledgeable about exactly what I was looking for when it came to the right brake pad for my needs (street/track). Come to find out the pads I picked (DBA's) were not the best pads for my application so im very glad I talked to ***!! I just recently had everything installed, bedded the pads and I am so happy I used GenRacer for my 16 R-Spec Coupe!! Thanks again ***!!!

So Awesome

Order came fast and looks amazing on my car. I did have one problem where one tail light would blink sequentially and the other didn’t. I sent an email late in the day inquiring about it. I wasn’t expecting a response until at least the following day as it was so late. Within an hour they had gotten back to me informing me of a switch on the inside of the housing where you can choose sequential or regular. Sweet! Top notch customer service.
