Hi Guys, I decided to keep modding my main A5 and I chose the RAP4 flexiair.http://i107.photobucket.com/albums/m283/kiwikenny/th_IMG_1525.jpg
As a few internet searches suggested issues with the flexible hose I went for the end cap only and added braided hose and elbows.this kit is a cut-down version of what they intend to use on the tamco magfed upgrade. MK5 INTERNAL AIR THROUGH UPGRADE KIT
. THIS is the cause of my issues.
IT HAS BEEN A DRAMA!!! even had the part replaced. The main problem was that the badly tapped and drilled air exit hole was coming into the end cap above the o-ring, preventing a seal.http://i107.photobucket.com/albums/m283/kiwikenny/IMG_1502.jpg
Managed to work around this by Loctiting in a CO2 inline on/off. Now it's all airtight and ready to go...... But now i hear a very small new hissing. turns out it's from where they have plugged the old exit port. you can see in this picture where I've put a drop of loctite in hope that may improve the seal.

If this doesn't work I have no clue what to do. It's getting expensive returning the parts to rap4 from New Zealand
