Progess, sort of.

I pulled the wastegate line. It was fuel hose. It was still in one piece but so brittle the ends broke as I removed it. I replaced the hose.

The real problem is the fact that my wastgate diaphragm is gone, I think. When I blow into it the air comes out the bottom of the valve. No pressure build up = no wastegate. Where do I get a replacement?

Also how do I test the overboost protection circuit? I want to know if the sender works, and if the overboost valve works.
