Jeremy:

As your new host, I do need photos...
Still trying to iron out my personal V8Q issues. BTW, nice site.

Also, I'm not sure if the 02 sensor is the same model/make as the one on 
the end. Share some part numbers and ideas.
If I'm going to replace all the hoses, (vac) then can you do a step 1, step 
2 etc until they're all done?

Thanks.
