There have been quite a few discussions of this issue over the years - try a search.

Most everybody agrees that the only way to change the bottom gasket was to remove the IP - but there was one person here that claimed he was able to replace the gasket with the pump in situ.

I remember when he said he was able to do this I immediately thought "no way" but the last time I had my car up on the lift I looked carefully around the area of the bottom of the IP and I came to the conclusion that it might be possible - but it sure wouldn't be easy.

When I resealed my the IP on my 91 2.5 turbo I removed the pump - once the pump is on the bench its a 15 minute job to change the seals.
