Thanks everyone. Got it off this morning. Now the spacer is stuck good to the old pump and working to get it off without damaging it, very difficult so far. Questions 1. there was no gasket between the block and the spacer, but the new kit came with one, should i put one between the block and spacer on the reinstall? 2. Should i use some type of gasket compund spread thinly on the gaskets? If yes, any recommendations in case brand matters? 3. If my existing spacer cannot be reused, does any one know where to get one the best replacement? several sites say it it no longer available but will have to wait till tomorrow to call any of the nissan sites they appear to have it but you never know if there websites are just not updated with correct inventory. Thanks
