      Just picked up a Stage 2 C2 turbo R32.. Don't know much about the build other than the basic things I can see and have been told, so bare with me..

      Driving the car conservatively the AFR would go from 14-17 and at WOT it leans out to about 13-14 which seems pretty normal.. I looked under the hood while at idle and noticed the fuel lines were leaking, tightened the clamps down all the way but still leaks. I'm guessing might be the 4bar FPR is stuck and causing it to be over pressurized, pump I'm told is a bosch 044, have not yet taken the car apart to verify that, but PO is pretty legit and I would take his word for it.

      Anyway, I have a 12v vrt and running an 034 rail w/ an fitted fuel lines w/ a nice FPR with gauge.. I tried looking for a similar setup compatible for a 24v and couldn't come up with any results. I figured this would be the best place to ask, since google doesn't always seem to find everything.

      Thanks for the help!

      I dont think that is very normal, I think you are close to causing severe damage/melting something ARF its usually 11-12.5 Max at WOT for most tunes of the shelve. Creeping to 13-14 is asking for trouble.

      leaks in the bay are dangerous, plenty of hot parts there around the turbo that could ignite it and burn your car to the ground.

      blue water and 034 sell those rails and also the FPR adapters on their kits. keep an eye on that AFR to stay 12 or below.

      how much boost are you running? turbo? and size injectors?

      Yeah I haven't driven the car since, just waiting on my fueling setup from 034 motorsport. 550cc injectors 6265 turbo and 8psi

      at 8psi you should be ok on fueling with an 044, check if it is working and you truly have a 4 bar fpr, I know of people using 3 bar ones by mistake, rating should be stamped on it.
      Do you have a head spacer to lower compression? if not dont raise the boost until you get one.

      Yeah there's a 9:1 headspacer how much boost can I run with stock internals? I was thinking of possibly swapping the rod bolts with arp ones. I just bought the 034 fuel rail w/ the fpr adapter and adjustable for capable of up to 5 bar and running 6an lines, got the surge tank as well putting the 044 in and running with a highflow dw 65 intank pump.

      No need for the dw in tank just to feed the surge tank, oem should suffice. You don't increase the fpr above 4 bar, it has a port for vacuum/boost for when you are at idle fuel pressure is not as much. When you are in boost it will be 4 bar plus whatever boost you are running.
