    Hydro assist steering, where to mount bigger power steering reservoir?

    Finally setting up my hydro assist cylinder and I see on most rigs they also upgrade to a bigger reservoir. Currently I'm running a power steering pump off of a duramax truck, drilled and tapped astro van box, and a 6" PSC cylinder. Factory reservoir off the back of the stock 4.3l pump with the extended fill neck that puts the cap up by the ac compressor. I'm planning on replacing the factory power steering cooler with as big as one as I can fit behind the grill.

    do I need to upgrade to a bigger reservoir?
    any ideas where to mount the damn thing? I burnt up about any decent sized spot under the hood with the OBA compressor and accessories.

    Extended fill neck and big cooler should be enough for most cases I think. I ran that kind of setup for years with sbc, k5 blazer and hyd.assist.. After ls swap I used c5 vette pump and its small plastic reservoir, again for years. Now I built big reservoir, but it was mostly for peace of mind.. If you really want more fluid capacity, you could try to make the fill neck as long as possible, also maybe bigger diameter. Just mount and support it properly that it doesn't fall of because of added weight.

        The only way I could figure out to mount mine was to lose the airbox, use a cone filter, and mount the reservoir to the radiator support. It's not ideal to not have an airbox, but it seems to work fine. At some point, I'll probably build a smaller airbox to fit the filter I'm using, but I haven't gotten around to it yet.

ID:	227829 That's ^^^ where I put mine, but I've got a bit more room to work with. If you've got a big reservoir and want a short, straight run into the pump, there aren't a whole lot of choices.


          EDIT: I just noticed this is a five month old post. Well, what do you expect from a noob...?

            I ditched the factory washer reservoir and used a small universal one, and combined with losing the airbox and going with a cone left just enough room for a larger remote reservoir in my S10
