      I've had the Spulen delete kit installed for about 1.5 years. Fixed my problem and I haven't had any issues since.

      So, I am getting ready to do the delete this weekend. I am planning to use @le0n's method of going into the tube off the throttle body for the vacuum.

      I have the IE blockoff plate. With the spulen kit you replace the intake manifold tube. What is the connector in the factory tube? It looks like there may be some sensor there, or is it something that goes to the vacuum pump? Is it OK to leave the original hose? Do I need to take out the part that is in the factory hose and replace it with a coupler, or just leave it as is?

      This is on a 2009 New Beetle convertible with BPS engine code.

      NVM. Now that I got the breather box out, I can see I will not do anything with the factory tube. The brake vacuum booster tube is being disconnected from the vacuum pump. I'll just replace the current tube like le0n specified.

On of the vacuum lines that connects to intake tubbing snapped off too because it was so brittle, it was the one more towards the right, any idea what it goes too?

The hose i broke looks like its for the seconday air pump but i couldnt get the other end out to replace the hose, i put it back together with some electrical tape and so far so good, just waiting for some time to get it out find the size for the hose and replace it.
      I am such a freaking amateur!

      I am having the same problem Hgarcia described. However, I am using the same universal tee that le0n showed.

      For anyone else that used le0n's method, how did you get the N80 tubing over the barb? It looks likehe cut the 1/8 and 1/4 barbs off and used the 3/8 barbs (the largest ones on the universal tee). My N80 goes over the 1/4 barb easily, but I cant get over the 3/8 end.

      How did you get it on each end? I can't easily disconnect the N80 tube to twist either end.

      Thanks!

      thought I'd add my 2cents.

      Had the delete kit from Spulen installed for a few years now, noticed that the hose gets soaked with oil and started to sweat through and the brake pedal would feel kinda weird until warmed up.

      So recently I switched over to the method in this thread where you tap the N80 line, so far it's working fine and I notice the brake pedal feels more consistent. will update once I put more miles on.



      The delete kit works as they intend, but it's not a good long term solution, the silicon hose will start to weaken and get soft.
      the block off plate holds up, I have the original thin plate design and it's fine, just the hose is having issues.
