1999 Mercedes Benz E320
Exclamation Seized aluminum (secondary pump injection valves)

I ended up breaking the aluminum secondary pump injection valve on the passengers side (41 on attached diagram) due to corrosion. I bought a junker 99 e320 and am trying to replace the broken injection valve with the one off of the junker. The problem is that no matter how much I try to gently coerce it out it will NOT budge. I have tried penetrant spray and it will still not budge. Any suggestions/ recommendations are GREATLY appreciated!
