Pic 1 - Remove the original regulator with 2 screws, first remove the two hose that is connected to the regulator one with the clip and the other one is the vacuum hose.

Pic 2 - This is how it looks when taken out if afraid keep the O ring in a safe place.

Pic 3 - U will need to grind off the section where my thumb and pointer is holding with a grinder.

Pic 4 & 5 - Notice that part with scar, just grind a little by little until u see the inner core.

Pic 6 & 7 & 8 - Sorry quite blurr, playing safe by using screwdriver to remove the core. Do it slowly. Remember there is a spring inside u will need it back.

Pic 9 - The part need to be removed.

Pic 10 - Without the top part.

Pic 11 - This spring is important don't loose it.

Pic 12 - Install the after market regulator tightly. Confirm the position first before installing the regulator.

Pic 13 & 14 - This is the position of the regulator. See properly. Re-fit back the return fuel hose and vacuum hose.

Pic 15 - This part no need to do if u got the meter with u if no then remove the other side of the fuel rail and attach to a fuel pressure meter to set the fuel pressure. This part quite complicated if u don't have a fuel pressure meter.

* I can help if u wan hahaha done .... after installing car no improvement only the ride smoother in gear change and can feel the car holding its power already .... worth changing ....

da adaptor (if u stand in front of the engine) is on ur right, u kenot terbalik it maa...unless ur one is those terbalik engines laa :rofl:
 
adaptor muz install at the end , back flow to tank tat side lah. coz fuel regulator is limit the fuel flow back to tank. tat y rise the pressure at fuel rail.

exp;
from fuel pump===>to fuel rail===>Fuel regulator===>tank.
