    When I had my engine starting party with a new 350 LT-1 that had sat for over 35 years, it started within 30 seconds. Small fuel leak was the only issue, and the smoke is from the header paint baking on.

    There's nothing wrong with running a hose from inlet to outlet and filling the pump with fluid. I don't see that as any different than putting a reservoir in the loop. I'm afraid of burning up the pump if I run it dry, and I don't have any AN10 hose except braided A/C hose, and I have no AN10 hose ends except o-ring A/C hose ends. I have a bunch of AN6 hose and hose ends.

    I've been trying to avoid dealing with the PS reservoir and wanted to do that during final assembly of the car. But I see no easy, quick solution to the problem right now. So I'm going to try to find a solution that works and go ahead and plumb everything including the rack. It will also let me check the rebuilt rack for leaks which is a good thing to do. That will probably delay my starting of the engine several days until I figure out which parts I need, get them ordered, and install them.

    I found a easy way to bleed the power steering system without the engine running. I just hooked up my 1/2 inch Milwaukee electric drill to the pump, and got the system bled, leaving one less thing to worry about while firing the engine.

    This engine is not a formerly running engine that has been sitting after just being shut down . It's a brand new GMPP crate 502 longblock that I upgraded into a Ramjet EFI engine using GM parts and a few upgrades like the Holley TB and bigger injectors. It had never been run since it was assembled by GM. Last year I disassembled it to a bare block and re-assembled it with new rings, a custom cam, roller rockers, new timing set, etc. I've also re-wired some of the ECU harness. So a lot has been changed and it still has never run. Hopefully soon.

    I really painted myself into a corner on the PS reservoir. The whole time I was building the car the PS reservoir was in the back of my mind and I figured it would be easy to add later but never thought too seriously about it. I spent all day yesterday trying to find one that would fit, and figure out where to put it. It has to be above the pump inlet which complicates things a lot. The inner fenders are angled, and pretty tight to the frame so they're not a good location for mounting it. I looked at putting it on the firewall but routing lines from there would be fairly difficult, and I made the firewall uncluttered on purpose . Plus the steering column is in the way unless I put it above it, which I think would look bad.

    I looked at putting it next to the radiator in front of the radiator support, but there's not enough vertical space there and the lines would have to penetrate sheetmetal twice to get into the engine compartment. Plus that's where my horns go. I even looked at putting it on the passenger side but there's no space there either, except on the firewall and routing lines from there would be "fun".

    So the only place I could find that made sense is below the alternator, just behind the radiator support. However, there's not much room there and these reservoirs are pretty big. Most of them are made to hold nearly a quart of fluid (the PSC one is 3.5" diameter and 8.25" tall) and the outlet is on the very bottom on most of them. The ones from Billet Specialties are almost 10" long and they won't fit in that space.

    I made a mockup of this one from Concept One and I think it's going to fit, but it'll be tight. It's 3" in diameter and a little over 7" long.



    I ordered it last night (not anodized) along with the AN10 hose and fittings. It's going to be tough getting the AN10 hose to fit because it's so close to the pump, and I need some length to allow for engine movement. So instead of Teflon hose, I went with braided stainless rubber hose figuring it's going to be easier to bend.

    This shows the space I have to work with...

    If it doesn't fit there, it's going under the fenderwell behind the radiator support....I think.

    I read that just the fluid level in the reservoir needs to be 2 inches higher than the pump. Next to the upper radiator hose looks like a spot, and what about hydro-boost lines?

    This is what I used in mine. I needed two -6 and one -10. Smileys $119. It was baffled too

    JT, I looked all over the internet for something like that reservoir, even used Google images and only found the Canton Racing ones that are application specific. It doesn't look like Smiley's offers that one anymore. Not sure if it would have worked either, given my space constraints.
