The strainer was my next try. Tank access on the w210 is in the trunk since I can't run the car all the wAy empty I have to change it with a quarter taankq.. What's the easiest way to change it for me?? I'll also clean the ip. I've replaced the shut off valve and oring also. I'm beginning to think the ip just leaks but i just don't know and that's an expensive "guess". Im in Oklahoma for school but live in Houston. Are there any people near meaning anywhere in ok, tx or surrounding states that just really knows this engine, and would be willing to help me with pay of course? I'm also happy to drive especially if my drive backhome is potentially more enjoyable. I miss th way this car used to drive
