Isx15 cm 2250 fuel pump and a turbo question

[aaronb]

I have the new bypass valve to install. Had to order a 17 mm hex socket because I couldn't find one locally. My oil pressure runs about 37-38 running down the road. I have replaced the inappropriate, delta p, and exhaust back pressure sensors. Haven't gotten farther into that yet. I was going to remove that small tube from the manifold up to the exhaust back pressure sensor. It seems stuck and I don't want to break it off. The overhead was just done.

I'm trying to get some preventive maintenance done as money allows. I know I'll feel a lot better when I have saved enough back for an overhaul.
