   Does any one have any idea the best way of connecting a pipe from the oil catch tank to the breather pipe from the JP4 covers? I have seen a couple of pictures on here of people that have done it but cannot find them. I know you need to remove the smaller breather pipe and block it off but with the other one can you get a fixing that connects to the quick connector or does it need to be removed and a standard low pressure pipe fixed to the section of the pipping where all four pipes converge.
   
   My explaination is quite poor so if needed I can provide pictures.

   my setup:
   
   
   I have both pipes going into the catch tank, and then a vent hole in the top of my catch tank.
   
   I've literally only today fitted a new intake pipe (for c2 inlet) and now have plumbed the small one back into the inlet, and the big one still goes to the catch tank.
   
   Hope this helps

   I attached mine to the plastic junction piec... the plastic pipe is a bitch to remove lol. I also used a bit of fish tank pipe to connect the smaller one to the inlet so it still has a vacuum

   Cheers guys that was what I was thinking, except for the smaller breather pipe.
   
   Raunchz, yours was one of the bay pics I was thinking off, I just started going through people progress threads. How come you decided to route both pipes to the catch tank and not just the one?

   I had to route it into the catch tank, where else could i have routed it?
   
   With the JP4 covers you're left with two outlets to do something with. As I didn't have a standard inlet, I had to put them into a catch tank. So I could have either joined them together somehow and had one single pipe going into the catch tank. But as I had plenty of spare fuel pipe and wider stuff, I just used what I had to connect it upto the catch tank.
   
   If I had a standard inlet then I could have plumbed them both back into the system.
   
   I'm not sure whether you'd get away with routing one back into the standard inlet after the TB and putting the other in the catch tank. Not sure about the MAP readings if you effectively connected the inlet after the TB to fresh air (inlet, through the little pipe to the camcover, then out the camcover to the catch tank) - plenty of people seem to do this so one would assume it's fine.

   The main reason I am fitting a catch tank is due to fitting iTBs so I cannot really route it back to the inlet, not sure if I could route to the brake vacuum pipe but I would rather not as I assume the assistance for the braking power would be reduced.
   
   I would thinking of blanking the smaller of the two breather pipes off, maybe getting a short piece of pipe from the smaller breather, blocking it off with a bolt and jubilee clip, juast having the larger breather going to the catch tank.

   yeh that sounds good.
   
   You'll need to tap into the inlet manifold with a barbed fitting, and then connect this to the brake vacuum servo.
   
   just need to either block the smaller pipe off, or remove the standard Y fitting (with the little take-off for the smaller dia pipe) and just fit a universal Y join that you can have a single pipe coming off the end.

   Yeah the brake vacuum pipe is already fitted. I had a push fit connector welded to the first part of the inlet manifold.
   
   I think I will just block off the smaller pipe part of the plastic part of the breather pipe configuration. Hope I can get the two pipes off without damage seeing this silly piece of plastic is worth almost £40.

   lol, the breather setup on the jp4 is expensive.

    I've come to the conclusion that He-Man must put these together as even standing on the smaller pipe and trying to pull it away from the joiner, it didn't budge. I think it is more likely to break so I am just going to put the pipe away as at least it can be replaced in the future if required.
