Hello all, While parking my car I was met with wafting smoke from the engine compartment. I popped the hood to discover a significant amount of fluid coming from what I believe is the high pressure hose of the power steering pump - specifically the flared coupling that connects the metal tubing to the rubber. It squirts out quite a bit of fluid as I turn the wheel (engine on). The leak appears to be from the rubber side of the connection. I am hoping to get some help identifying exactly which part I will need to replace. There seems to be some variety in these hoses for each model year. I think the part begins with 3A719, however, there seems to be several subtypes indicated by a letter. One forum suggested the VIN would tell me, which might make my car the "F" subtype? For context, the pump is original and was attached to a 5L 302 with a 4 barrel, however, I rebuilt a 5.8L 351W, which I have been driving everyday, without incident, for the past 8 months or so. At this point, I know nothing of why this happened, and I understand it can be a variety of things ranging from a bad hose or clog or bad everything. For now, my main goal is to track down some kind of part number I can use to order a replacement for this section of the hose assembly. Appreciate any help in advance. The photos below show a driver side/top side view of the PS pump and the hose. After running the car a second time to confirm the location of the leak, the leaking fluid came out much more frothy and pink. Some of the other fluid in the picture is transmission fluid, which is from an old leak I am already aware of. I also included a picture of the underside to help identify the general shape of the tubing. Hope it helps. Thanks.
Bear with me here...I have some pics attached that may help with my questions. I pulled apart my pump that was working fine, but leaking quite a bit. Too much grime to tell for sure where it was leaking, but I suspect from the opening in the reservoir where the high pressure hose connects, and from the lower front of the reservoir, probably due to the reservoir main gasket failing. When I removed the reservoir, I see what appears to be a very thin gasket at the back (inside), where the high pressure end of the pump exits the reservoir. See photo of the remnants of this "gasket". I also included a photo of a gasket that came with a remanufactured power steering pump - is this similar to what should be used? It also appears that the metal around that opening is slightly distorted inward. It was easy enough to hammer it back to flat. Is there supposed to be a gasket where I am describing? Would it come with a rebuild kit (or a pump gasket kit, if that's all I need)? How thick is that gasket? Could someone have put an incorrect gasket, and could that have caused the metal to distort as the reservoir retaining nut was tightened? As far as the large o-ring that seals the pump to the reservoir - it LOOKS fine. Do they typically fail this way? Just start leaking, even though it still appears flexible with no apparent breaks or flat spots? Are there any tricks/tips when re-assembling the reservoir to the pump? (anything stupid that people do, until they learn the right way...) Lastly, any good sources for a gasket kit for these pumps? Thanks for the help. Tom
