Hey guys! Ive been sitting at work pondering and searching and tryin to figure out what power steering pump to use? I am running a chevy 305 and I have a Mustang II power rack and pinion. My understanding is the GM pumps produce 3 gpm and the rack only needs 2 gpm, so if you run it straight the steering is twitchy and it blows the seals in the rack. I read where a few people use an adjustable valve, but the reviews were 50/50....some like and some hate it? Another solution is to buy a GM pump that is valved for the MII rack, but they were roughly $200, but if anybodys used them and its worked like a charm I guess thats money well spent? Anybody had any exprience with them? A cheaper option I found was a valve that screws into the back of the pump to restrict the pressure from 3 gpm to 2 gpm....andybody know anything about this? This is only $20. I already have a brand new pump, so to me this seems like the best deal....if it works? I dont want to cut any corners with steering as it is a very important operation of any vehicle, so if anybody has any first hand experience or other options, Im all ears! Thanks guys!
