Yim Shan Wu was the most senior of Ku Yu Cheung's students. Fu style bagua was a commonly practiced style amongst students and contemporaries of Ku's because Ku Yu Cheung, Fu Zhen Song, and Sun Lu Tang were all friends and exchanged knowledge at different times in the early 20th century. They were considered to be among the greatest martial artists in China after the National Wushu Fighting Examination in 1928.
Wong Jack Man was among Yim's top students. He had begun his studies under Master Yim at age 7 and was considered to be a prodigy. So much so that he was given a letter of recommendation from Yim Shan Wu to go and study under Ma Gim Fung who was Shun Yu Fung's most notable student. I'm not sure where he learned it, but Wong Sifu knew Fu style bagua. I know most of his senior students (my sihing's) learned Fu style mainly from Lin Chao Zhen. I know Peter Ralston learned a little bagua from Wong but generally he didn't teach it. Wong Sifu did teach Sun style Hsing Yi which, if I'm not mistaken he either learned from Yim Shan Wu or Ma Gim Fung (or both). I'll have to check on that. He also taught Ku's Tai Chi which was developed because of the interrelations between Sun Lu Tang, Fu Zhen Song, and Ku Yu Cheung. All three men traded knowledge and developed their own Tai Chi forms.

The three components of combat are 1) Speed, 2) Guts and 3) Techniques. All three components must go hand in hand. One component cannot survive without the others." (WJM - June 14, 1974)
