This N249 bypass mod, FAO all of those who seem to dont understand it..

So in your opinion Matthew, it's not worth doing. ..?

I don't think so myself mate, but it depends on why you want to do it.......It won't gain you any performance IMO, but i guess it simplifies things under the bonnet.

So why do we need the T? Does the FPR use the same nipple on the inlet? My last one I had them lines done separate so the line from the DV was direct I think lol

I did this to my cupra 180 earlier, it took less than 10 minutes, i really cant see what the fuss is all about either now !



Step by step long winded guide, if you cant do it after this then either dont do it or get someone else to lol..

Basically all you need is about 3/4 a metre of 4mm internal diameter silicon hose like so -

So buy 1m

Then you need a plastic 6mm at each connection, t piece like so

Then look at this

1) Remove the black box (red number 3 in picture), which is being pointed at by the lime green arrow, 3 bolts, need a allen key to remove these.

2) Cut the rubber hose thats going into it (yellow arrow) and then throw the black box away (number 3 again), use one of the bolts youve just removed to remove the box, and shove it down the open end of the hose youve just cut (yellow arrow again) to bung it up.

3) Remove the top small hose thats coming off your dumpvalve (number 1 in red on the picture), shove another one of them bolts down the open end of that hose to bung it up.

4) Bin the 3rd bolt or keep it, whatever

5) Take your new bit of hose you got off ebay or whereever, push it onto the top of the dumpvalve to replace the hose you just removed/bunged up, it goes where the red number 1 is in the pic.

6) Remove the hose that connects the fuel pressure regulator to the inlet, this goes down behind and underneath, so first remove it from the regulator, (red arrow) if you look where it goes you will see, pull this hose off and discard it, its about 10 inches long and feels like textile/braided.

7) Take your new hose which you connected to the dumpvalve earlier ( red number 1 in the picture, and feed it down, under however you like and connect it to under the inlet where you just pulled off the old hose that ran to the fuel pressure regulator

8) So now your new hose should connect the dumpvalve to the inlet, what you need to do here is cut the new hose near the fuel pressure regulator, and insert the t piece to rejoin these hoses, then run the offcut of new hose you should be left with from the left over connection on the fuel pressure regulator

9) Slap yourself on the forehead after realising how easy it was and for posting 60 questions time and time again on how do it!

Hi, do you still have the photos you attached? They seem to not be loading on my end. Cheers.
