I guess I was lucky getting the anti tamper screws out of the TPS with a T15 bit. I suppose they are, "anti tamper" so a weird size is "anti tamper".

That is not good, cracking fuel hose on a fairly young car like yours. Certainly worth checking the injector hoses next time the fan is off. I have braided hoses fitted, so it's not easy to see the hose condition, a positive or a negative? I am sure you know but the fuel hose is in the APL, Cohline 2240.0600.
