I am doing the vacuum pump diaphragm on my 1980 td this weekend. It has the old style, two-outlet pump.

I guess I am extra thick on some things, and obviously this job is going to be one of them. I am not getting the vulcan mind-meld with the postings I've seen on the job.

1. I read that I can do this easily with the pump in place, by just pulling off the front cover. Is this true?

2. Right now I have no vacuum to speak of, but no oil in the vent line either. Should I just go ahead and order the 'big' rebuild kit with the check valve pieces? (Note: I THOUGHT that was what I had bought until I got to the parts counter today. DOH. Should have known it was way too cheap....).

Thanks
