I have already bought a new one. I honestly can't afford the downtime any longer on the vehicle. If I had another car I totally would try to fix it, but I need this running, and I don't have the time to keep taking my wastegate on and off the car. I contacted tial and all they asked for was the serial number on top of the wastegate and they said I can send it to them and they will inspect/test it and decide what to do from there. I am hoping that they will repair or replace it once they test it and find it faulty, but they may not because they may realize someone put 1/8 NPT fittings in it when it isn't designed for that, and that could be the reason it failed as it was leaking right where the fittings go in, not from the fittings, but nonetheless right where they were. If they repair or replace it I will sell it to try to recoup some of my loss.

Here are some pics and a quesiton:

These are the fittings I got so I can use my nice 4AN lines:

My question/problem ATM is that the fittings are slightly longer than the banjo fittings that come from tial. The top one fits just fine because there is more room and I made sure it would not hit the diaphragm at all, and it won't. The bottom fittings are a little different, after the threaded portion it appears the diameter of the hole gets slightly smaller so I cannot thread my fitting in far enough to get a seal (it still doesn't hit the diaphragm as there is plenty of room length wise), so I was going to just use a few washers to fix this problem. I just want to make sure that is OK and that it will still seal? And if so, since the washers are slightly different sizes which order should I place the washers onto the fittings? I have pictures below to show what I mean.
This way?

This way?

Or this way?

The top fittings looks like this:

Thanks!
