X2 on Wolf's post,(may not be same place but same area).
Coast Industrial Parts 562 Dupplin Road (across from Mayfair).
I had to replace some parts on my Seastar system, and also have some custom made, (changed fitting angles to reduce rubbing/stress) and Seastar wanted a lot of $$$.
I have a friend who is an engineer on one of the big Coast Guard boats and he told me that the Coast Guard gets all their hydraulic parts etc.. from there. I went down there (took my old parts with me, just like Wolf said) and they made custom hoses and actually fabricated fittings for me in less than 45 min. They actually had to make the fittings, and charged me $12 each for them, forget what the hoses were worth, but recall that they were better and cheaper than the Seastar ones. Really good guys.
