Get a stock "P" pump and get the "reservoir" from PSC which has a -10 inlet on it to feed the pump from your reservoir.
You can get the reservoir from PSC for like $35. You can get it from Advance, etc. but it doesn't have the -10 inlet on it but rather has like a 1/2" and its about $65 and a new pump with that reservoir is about $95.
You can get a Dorman serpentine pulley for that pump at Advance as well and is about $13
