I needed to rebuild my MPS but Chris Foley is out of the kits due to no longer having a supplier of the BE-CU diaphragms . I was lucky enough to have a member here offer to sell me his spare parts kit from Chris (Thanks Tom). His kit did not have the instructions with it so I am wondering if anyone has a copy of those instructions?

For me it was also very helpful to install a vacuum gauge off of a T from the MPS hose. This helped know when at full load and part load while watching the AFR. It helped to see what vacuum the MPS was seeing and how it responded.
