: Big Block Short Water Pump Power Steering-Help!
SSuper Dave Jan 31st, 03, 10:22 PM I am installing power steering on my '68 short water pump 427 and have gotten all of the factory parts. The brackets and pulleys line up great and I have installed the return hose and now have a problem. The "correct' hoses that I got from Ground Up has a male flare fitting on the end of the pressure hose that goes into the pump. But the pump also has a male end on it! Which of these is wrong and which is correct? I tried replaceing the pump fitting with one from another pump with a female fitting, but the ferrule on my hose bottoms out before the flare will tighten up, so no go. And according to the assy manual, the pressure hose just loops up under the alternator and looks like crap! Anyone have any pics to post? I need to get this resolved. Thanks to all.

SSuper Dave Jan 31st, 03, 11:42 PM Thanks!! Just need a correct fitting for the rear of the pump. Off to the junkyard I go.

DaleM Jan 31st, 03, 11:42 PM Sounds like the wrong pump. I had a two-piece pump on my 67 (w/69 long pump engine) 'till I swapped out the pulleys for a March setup. March suggested a 71 Impala 454 pump and I used the existing '69 pressure hose for it, i.e. male end on the pressure hose.
SSuper Dave Feb 1st, 03, 7:06 AM Its a pump with remote resevoir and everything fits except the fitting onthe back for the pressure hose. Someone probably swapped it in years gone by for who knows what reason. I want to keep the stock appearance.

JIML82 Feb 2nd, 03, 5:47 PM Nearly all Chevrolet power steering pumps had a male end on the discharge fitting through the 1969 model year. In 1970 Chevrolet changed to the standardized Saginaw Steering Gear 5/8-18 UNF female 45 degree flare port in the discharge fitting.
So through 1969 the Chevelle required a power steering pressure hose with a 45 degree flare on the tube and a female nut.
In 1970 Saginaw Steering Gear began manufacturing all the pumps and power steering hoses for Chevrolet. At that time the hose continued with a 45 degree flare on the tube, but the nut changed to a male 5/8-18 nut.
SSuper Dave Feb 2nd, 03, 9:37 PM Now I'm really confused! I took a discharge port off of a '69 smallblock pump that I have, it is female. But while my hose will screw into the port, the fitting bottoms before the hose gets tight as the port has a flared bottom and the two flares won't seal. I need a female port with a reverse flare or bulge up in the bottom so my flared end hose will seat. All the hoses are run and routed correctly, so I'd rather change the port. I will look at some pumps at the yard tomorrow and see what I can find. What year did the fitting become metric, so I won't be wasting my time looking a too new of a car? And shoud I grab the flow control valve (spring loaded thing under the discharge port) to go with the port? I see a few differences between the two that I have. Thanks a lot to all, this is really bugging me!

JIML82 Feb 2nd, 03, 11:41 PM The power steering fittings became metric in 1980. You want a brass 45 degree flare insert inside the discharge fitting. The metric fitting does not have the flare. If I remember correctly a M16x1.5 nut will screw right into a 5/8-18 UNF port.
The metric o-ring tube end configuration won't fit very well into 45 degree flare port. However, a 45 degree flare tube will assemble into a metric o-ring port but it won't seal at all regardless how tight you try to tighten the nut.
SSuper Dave Feb 3rd, 03, 9:35 PM Found a female discharge (LOL!) fitting on a parts pump at the dealership, swapped it and the flow control valve and now my hoses are done. Thanks to Bill Rose for the pic of the correct routing, the remote resevoir pump and hoses look like an afterthought from the factory, but its correct and done, just needa belt and I'm steering one handed again! Thanks to all who responded.

JIML82 Feb 5th, 03, 8:14 AM I'm sorry that I didn't think of this picture in my earlier posting. This might make it clearer as to the differences between the 45 degree flare fitting and the o-ring fitting that is used on 1980 and newer pumps and gears.
Go to www.corvettefaq.com (http://www.corvettefaq.com) and look under Steering. Download the following "Hose Connections - Flare versus O-Ring". The drawings specifically show the pump connections.
The fact that a M16x1.5 metric nut will screw right into a 5/8-18 UNF port makes this connection confusing to a lot of people. This might make things a bit clearer.
